A common malformation of a branch attachment in a tree is the inclusion of bark within the join, commonly referred to as a 'bark inclusion' or 'included bark'. This malformation is known to weaken the connection of the branch to the rest of the tree's structure, as it acts to block the formation of the axillary wood at the branch attachment's apex.Lonsdale, D. (1999) Principles of Tree Hazard Assessment and Management, TSO: LondonSmiley, E. T. (2003) Does included bark reduce the strength of co- dominant stems? Journal of Arboriculture 29 (2): 104-106Slater, D. and Ennos, A. R. (2015) The level of occlusion of included bark affects the strength of bifurcations in hazel (Corylus avellana L.) Journal of Arboriculture and Urban Forestry 41 (4): 194-207 Bark included branch junctions are commonly found in a wide range of tree species, and are primarily caused by the effects of natural bracing within the crowns of the trees.
White ash exhibits a little more resistance to the EAB than green ash, which has nearly no resistance; however this could also possibly be due to white ash not being used in landscaping as extensively or placed in high-stress environments.Andrea C. Anulewicz, Deborah G. McCullough, and David L. Cappaert. 2007. Emerald Ash Borer (Agrilus planipennis) Density and Canopy Dieback in Three North American Ash Species. Arboriculture & Urban Forestry 2007. 33(5):338–349.
Returning to the United States, Phelps spent most of his time resting and working on his most important hobby—his estate. His great passion was trees and the woods; he was a devotee of arboriculture. Between 1875 and 1880 Phelps was responsible for planting approximately 600,000 trees of numerous varieties. In 1880 Phelps was selected to manage the Republican Presidential campaign but he was unable to complete the assignment because of feeble health.
An ISA "Certified Arborist" may not be equivalent to an "Arborist" who is "Certified". Several colleges like Portland Community College of Oregon, offer Certificates in Landscape Technology, through courses which include arboriculture, tree identification and other horticulture classes. A student from one of these colleges may function in business with the title "Arborist", and possess the related but different certificate or qualification. In which case they would be an "Arborist with a certificate of qualification".
It should also be noted that the general way to distinguish a certification from a certificate or a qualification is certifications in arboriculture will expire, and will need to be renewed on a regular and ongoing basis. Part of this renewal process will always include keeping CEU,s up to date. The certificates or qualifications provided by colleges typically do not expire nor do they require any further ongoing education to remain valid.

He was the founder of what was to become the Ecole Du Breuil. He retired in 1883.
Douglas Boin, A Social and Cultural History of Late Antiquity (Wiley-Blackwell, 2018), pp. 183–184. The tablets are presently conserved at the National Museum of Antiquities and Islamic Art in Algiers, Algeria. The place where the documents were found is Saharan pre-desert at the limit of the cultivable zone and of permanent human settlement. The tablets show that in the Vandal period arboriculture (including of olive) and floodwater irrigation were practised in the area.
Fairlands has a parade of eight shops, a post office, a doctor's surgery, primary school, recreation ground and community centre. The latter is used for resident's association meetings, meetings of other groups of cross-sections of the community, and private hire events. Directly north of Fairlands is the Equestrian Centre of Merrist Wood College, which specialises in horticulture, landscaping, garden design, animal care, countryside, golf, sports turf, floristry, arboriculture and equine studies - it encompasses of land.
France Adamič (4 October 1911 – 5 August 2004) was a Slovenian agronomist and author of several books on horticulture. He was professor of arboriculture, pomology and introduction to farming on the university in Ljubljana from 1961 till 1981. He was researching domestic and foreign cultivars of fruit trees, their physiology, the technology of their cultivation, and the organization and economics of fruit tree plantations. Adamič graduated from the University of Belgrade, where he also completed his doctoral studies.
McIvor trained in horticulture and arboriculture and worked at Kew before taking up in 1848, a position in southern India as superintendent of the yet to be established Ootacamund botanical garden. At Kew, McIvor took an interest in bryophytes and published a pocket herbarium of British hepatics in 1847. He established the botanical garden at Ootacamund and worked there until his death. He married Anne, eldest daughter of Colonel Edwards of Iscoed, Denbighshire on 31 May 1850.
The Tree Line USA program recognizes public and private utilities for their use of best practices in arboriculture, primarily following the ANSI A300 guidelines from the Tree Care Industry Association on tree topping and pruning, tree removals and planting, and trenching or tunneling near trees. In order to qualify, a utility must also provide annual training for their workers, educate the public on tree planting and the use of trees for energy conservation, and sponsor an Arbor Day celebration.
In 1970, Mynors retired from his teaching duties and relocated to his estate at Treago Castle. Though he cultivated leisurely pursuits, such as arboriculture and a stamp collection, his retirement saw work on a commentary on Vergil's Georgics, which appeared posthumously in 1990. He also maintained an interest in the nearby Hereford Cathedral. On 17 October 1989, Mynors was killed in a road accident outside Hereford on his way back from a day working on the cathedral's manuscripts.
Where a junction forms in a tree and bark is incorporated into the join, this is referred to as an 'included bark junction' or 'bark inclusion'. A common cause of bark being incorporated into the junction is that the junction is braced by the touching of branches or stems set above that junction (in arboriculture, these branch interactions are termed 'natural braces'). Such included bark junctions can be substantially weaker in strength than normal tree forks, and can become a significant hazard in a tree, particularly when the bracing branches are shaded out or pruned out of the tree.Lonsdale, D. (1999) Principles of Tree Hazard Assessment and Management, TSO: LondonSmiley, E. T. (2003) Does included bark reduce the strength of co-dominant stems? Journal of Arboriculture 29 (2): 104-106 Research has shown that in hazel trees, the more the included bark is occluded within new wood growth, the stronger that junction will be, with the weakest forks being those with a large amount of unoccluded bark at their apex.
Transactions of Royal Scottish Arboriculture Society 12:371-374. It readily colonises heathland and acidic woodland habitats in southern England, often forming very tall and dense evergreen stands which smother other vegetation. Although heathland managers widely regard it as a problem weed on unmanaged heathland, it is readily browsed by cattle (especially in winter), so where traditional grazing management has been restored, the dense stands become broken up and the plant becomes a more scattered component of the heathland vegetation.
The current Principal of the college is Jeremy Kerswell. The range of courses cover land-based provision including Agriculture, Horticulture, Floristry, Greenkeeping, Hard Landscaping, Equine Studies, Agricultural and Horticultural Machinery, Metalsmithing, Animal Care and Veterinary Nursing, Countryside Management, Forestry and Arboriculture, Sports (Outdoor Education), Viticulture and Oenology, and Rural Business Management. The college was visited by The Princess Royal in March 2008 to open a new Children's Rural Education Centre marking the Year of Food and Farming.Plumpton College royal visit - picture special - Local.
Cleghorn wrote the entries on "Arboriculture" and "Forests and Forest Administration" in the 9th edition of Encyclopædia Britannica (v. 9:397–408). He also made a study of the agriculture and botany of Malta and Sicily in 1868. Robert Wight dedicated a genus, Cleghornia, to Cleghorn in 1850, "a zealous cultivator of Botany, but more especially directing his attention to Medical Botany". He died at Stravithie Castle, near the village of Dunino west of St Andrews, Fife, on 16 May 1895.
Bypass secateurs Pruning shears, also called hand pruners (in American English), or secateurs (in British English), are a type of scissors for use on plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required. Loppers are a larger, two-handed, long-handled version for branches thicker than pruning shears can cut.
Askham Bryan College is a specialist land-based college based in Askham Bryan, York, England. It also has centres in Leeds, Newcastle, Middlesbrough, Guisborough, Bradford, Wakefield, Scarborough and Penrith. It was built in 1936, but not opened until after World War II as the Yorkshire Agricultural Institute. The college runs courses in Agriculture, Animal Management, Veterinary Nursing, Equine Management, Engineering, Motor Sport, Horticulture, Arboriculture, Floristry, Countryside Management, Outdoor Adventure Sport, Sports Development, Coaching and Fitness, Uniformed Public Services and Foundation Vocational Programmes.
In January 2014, the college was granted permission by the West Lindsey District Council to move to the grounds. In October 2014, construction began after £6 million had been secured from the Skills Funding Agency Capital Investment Fund. The new campus was to have science laboratories, agriculture, engineering and arboriculture workshops, an animal management facility, a farm and a halls of residence for students. It was expected that a significant portion of the college's intake was to be attracted from South Yorkshire.
The degree to which horticulture or small-scale agriculture was practiced by Jōmon people is debated. The hunter-gatherer conceptualization of the Jōmon period culture is part of scientific romanticized narratives. There is evidence to suggest that arboriculture was practiced in the form of tending groves of lacquer (Toxicodendron verniciflua) and nut (Castanea crenata and Aesculus turbinata) producing trees, as well as soybean, bottle gourd, hemp, Perilla, adzuki, among others. These characteristics place them somewhere in between hunting-gathering and agriculture.
The architecture of Middle Preclassic structures consisted of hardened adobe bricks that served, later, as foundations for raised platforms and pyramidal temples. Excavations indicate that from early in the Middle Preclassic the community was large enough to produce heavy refuse deposits. Cotton was grown as well as maize; palaeobotanical research also has identified annonas, avocados, cacao, black beans, palm nuts, plums, and sapodilla (zapote blanco). Arboriculture developed – with groves of crop trees grown in terraces down to the edges of great ravines.
A 10-year evaluation of the performance of four elm cultivars in California, U. S. Journal of Arboriculture, March 2004. although the tree again proved only moderately tolerant of elm leaf beetles. The tree is currently being evaluated in the National Elm Trial coordinated by Colorado State University. 'Frontier' has had a limited introduction to Europe, where it is largely restricted to arboreta and elm collections; it also featured in trials in New Zealand during the 1990s at the Hortresearch station, Palmerston North.
The Institut Redouté-Peiffer was created in September 1996 from the merger of the Institut Pierre-Joseph Redouté and the Institut Serge Peiffer. The Institut Pierre- Joseph Redouté gets its name from the painter of roses, a watercolourist born in Saint-Hubert, Belgium in the 18th century. In 1913, the provincial college of then-province of Brabant set up a gardening school. Over the years, other sections were opened: floriculture, fruit arboriculture, floristry, additional subjects for horticultural professionals, and a high school for landscape gardening.
Otto Schneider-Orelli (10 August 1880 in Münchenbuchsee - 31 October 1965 in Zürich) was a Swiss entomologist. He studied natural sciences at the universities of Neuchâtel (1899) and Bern (1900–05). Following graduation, he worked as an assistant under Hermann Müller-Thurgau at the research institute for arboriculture, horticulture and viticulture in Wädenswil, where from 1913, he worked as an entomologist. From 1928 to 1950 he served as an associate professor of entomology at ETH Zurich and as director of the Institute of Entomology.
Carabiners are widely used in rope-intensive activities such as climbing, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular.
All of them presented the Weipers Memorial Lecture, a biennial talk at the University of Glasgow. On his retirement Weipers devoted time to arboriculture but also played a role in the establishment of academic aquaculture, as chairman of the management committee of the Nuffield Institute of Aquaculture, at the University of Stirling. For this work he was awarded an honorary doctorate (LLD) by Stirling University in 1978. He was later awarded the honorary degree of Doctor of Veterinary Medicine and Surgery by his alma mater (1982).
Online reference Lord Dulverton and his wife Lady Victoria further developed the garden particularly the formal areas and the Walled Garden. During the Second World War the area became overgrown and neglected but after he inherited the property in 1956 the 2nd Lord Dulverton restored the garden and returned it to its former beauty. In 1992 the 2nd Lord Dulverton died and left the Arboretum to the Batsford Foundation which is a charitable trust which promotes research and education into conservation, arboriculture, gardens and architecture.
Euroflora is an exhibition of flowers and ornamental plants. It represents one of the main events that take place in the Mediterranean and in the world on research to plant hybridization, cut flowers, potted plants, arboriculture, gardening and landscaping. It is organized by Genova Floralies with the support of municipality of Genoa. It is an event recognized by Association Internationale des Producteurs Horticoles (AIPH) and it is part of Association of International Floralies (AIF) founded in 2005 together with the Floralies of Ghent and Nantes.
The tree is California Historical Landmark No. 2 (No. 1 is the Old Customhouse in Monterey). It is recognized by the National Arborist Association and International Society of Arboriculture for its historical significance as "a campsite for the Portola Expedition Party of 1769"; being frequented by the Costanoan/Ohlone Indians; and for its use as a sighting tree by surveyors plotting out El Camino Real. The tree is depicted on the city of Palo Alto's official seal and on the seal of Stanford University.
The works depot was removed from the eastern side of the main avenue of Hyde Park north in this period.SOHI, 2014, 6 In 1999 the men's conveniences at St. James Station were converted into a cafe facing the park's north-western corner (off Market Street/Elizabeth Street intersection). Nagoya Gardens were upgrade. In 2004-5 an arboriculture survey of the park was undertaken, after an outbreak of fungal attack meant the need to remove some of the park's central avenue of Hill's figs (Ficus microcarpa 'Hillii').
In 2009 he was awarded the Associate of Honour by the RHS for his services to horticulture. Only 100 people to hold this award in the British Isles. Named one of the most influential Londoners in the Evening Standard's Progress 1000: London's most influential people 2016 In 2015 he was awarded Honorary Lifetime fellow of the Arboricultural Association recognising the significant and positive impact he has made to Arboriculture. William Aiton medal by Royal Botanic Garden's Kew in December 2016 for exceptional services to Kew.
In 2019 he was awarded the Victoria Medal of Honour (VMH). The award was established in 1897 "in perpetual remembrance of Her Majesty's glorious reign, and to enable the RHS Council to confer honour on British horticulturists." Only sixty-three horticulturists can hold the VMH at any given time, in commemoration of the sixty-three years of Queen Victoria's reign. He was also awarded the MBE in the Queen's New Years Honours list in 2019 for services to the Royal Botanic Gardens, Kew and Arboriculture.
He made provision in his Will to leave the Marks Hall estate to the nation in the interest of agriculture, arboriculture and forestry. During the Second World War, Earls Colne Airfield was built on the edge of the deer park and much of the property requisitioned for used as the headquarters for a number of local airfields. The 97th Bombardment Wing headquarters was initially located at the manor. By 1949, the mansion was neglected and said to be in a dangerous state, and was demolished in 1950.
Throughout her life in Greece, Sophia was actively involved in social work and helping the underprivileged. Following in the footsteps of Queen Olga, she led various initiatives in the field of education, soup kitchens and development of hospitals and orphanages. In 1896, the Crown Princess also founded the Union of Greek Women, a particularly active organization in the field of assistance to refugees from the Ottoman Empire. Fascinated by arboriculture and concerned by the fires that regularly ravaged the country, Sophia was also interested in the reforestation.
The natural stone of the Transjordan region is beds of limestone and chalky limestone laid down in marine deposits in the Eocene and raised above sea level as the Belqa Group in the middle Eocene. Their relatively soft stone is extensively transected by eroded wadis and is covered by meters of erosional soil termed terra rossa The Abila site is covered by approximately a meter of another, closely related soil, Rendzina. Both soils are fertile, contributing to the agriculture and arboriculture of the area.
La Floresta was formed in 1909 when Dr. Miguel Perea, lawyer and founder of several banks, began planting pine and eucalyptus trees on a large area of sandy ground between the Sarandí and Solís Chico streams and from the town Mosquitos (known today as Soca) to the River Plate. In March 1911, it became a tourist resort for arboriculture and bathing called La Floresta. The resort was mostly completed in 1920. On January 3, 1915, the tallest building in the resort, the Hotel La Floresta was inaugurated; it was expanded in several stages through 1921.
Evidence of the area's history can also be seen today with the pill box to the east of the gardens. In April 2007 the local newspaper, the Blackpool Gazette confirmed that the gardens were to receive attention from Blackpool Council's Ranger Service and Arboriculture Service to restore the gardens after years of neglect. The site has been granted special status as a designated County Biological Heritage Site (BHS). A five-year site Management Plan was put in place to assist the long term maintenance of the site, protect wildlife and attract more visitors.
In 1996, NZ Arb joined the International Society of Arboriculture (ISA) to become its 32nd Chapter. Every year, NZ Arb holds an Annual Conference, with national and international speakers, normally held in conjunction with the NTCC. Also, throughout each year, a number of technical seminars or workshops are held, as well as social events and field trips. The Association manages regional Tree Climbing Competitions (TCCs), culminating in the National Tree Climbing Championship (NTCC) - the respective Men’s and Women’s Champions go on to represent New Zealand at the International event (ITCC) run by the ISA.

He has been granted an adjunct research appointment to the Illinois State Museum Botany Department and an adjunct faculty position in Biology at Illinois College. Sternberg is a charter life member and past chapter president of the Illinois Native Plant Society. He also holds life memberships in the International Society of Arboriculture (from which he received a Special Recognition Award for his work with historic trees), the International Dendrology Society, and American Forests.
By 2013, Capel Manor College offered 65 courses across its campuses in subject areas such as, animal management, saddlery, horticulture, garden design, arboriculture and floristry. The Royal Agriculture University became a partner and validating university for all degrees at the College in 2015. 2018 saw Capel Manor College celebrate its 50th anniversary and win Gold at the RHS Chelsea Flower Show and Gold at the Ideal Home Show, and in 2019 the College’s students, apprentices and staff, designed and built the world’s largest show garden at The Game Fair event held at Hatfield House.
Modern Laconia is a political subdivision of Greece covering the Eurotas Valley, the massifs on either side, the two headlands, and the enclosed Laconian Gulf with its coastal islands. Its seat is the city of Sparta, as in ancient times, at a site which dominated and still dominates the valley from its central position. However, the rich-soil plain is entirely divided into villages that practice agriculture, viticulture, and arboriculture intensely. The main roads from Sparta form a branching network leading out radially from the city to connect other cities and towns in the valley.
This link to an Ontario Ministry of Agriculture Factsheet gives details and diagrams for the technique. However, modern arboriculture suggests that the application of pruning paints and wound dressings can inhibit the trees' natural defenses, so a person attempting this technique may try it without the application of wound dressing prior to the graft insertion. Most trees will produce callus tissues compartmentalize the wounded area. This natural defense is stimulated by environmental factors which may include the presence of the 'first arrivals' of fungi and bacteria on the wet wound.
Pershore College is situated on a 60 hectare site near Evesham, Worcestershire (though close to the Warwickshire border) and offers courses in Horticulture, Arboriculture, Animal Welfare, Veterinary Nursing, Agritech and Countryside Management. The resources include a commercial plant nursery, plant centre, fruit unit with fruit juice production and pick your own facilities, amenity grounds and commercial glasshouses. The College also manages several national plant collections in the popular and much visited College gardens. The College is home to the Royal Horticultural Society Regional Centre and the Alpine Garden Society.
Sir Richard lists his hobbies in Debrett's as silviculture and arboriculture and has held various business posts in connection with these, including as chairman of Sir Harold Hillier Gardens and Arboretum Management Committee from 1989 to 2005, a trustee of The Royal Botanic Gardens Kew Foundation from 1990 to 2003, a director of Castle Howard Arboretum Trust (CHAT) from 1997 to 2013 and chairman of the International Dendrology Society from 2007 to 2012. He was also awarded the Veitch Memorial Medal from the Royal Horticultural Society in 2005.
The glen was developed in the 1860s by a consortium of Manx businessmen interested in arboriculture. They carried out extensive planting of trees and ornamental shrubs, laid paths, constructed river bridges and opened the site to the public in 1867. The attractive name Glen Helen was probably chosen from Greek myth to reflect the beauty of the location. Isle of Man Department of Environment, Food and Agriculture Today a variety of mature and impressive trees including sequoia, thuja, spruces, Douglas fir, oak, sycamore and beech can be seen.
All examples included in 10-year trials at Atherton, California, to evaluate replacements for Californian elms lost to disease were withdrawn after a combination of rapid growth and poor structure condemned the trees as "likely to require more maintenance than most municipalities would find acceptable".Costello, L. R. (2004). A 10-year evaluation of the performance of four elm cultivars in California, U. S. Journal of Arboriculture, March 2004. However, these verdicts may reflect in large measure the fact that they were grown in warm climates but with minimal weed competition.
It differs from the transplantation of larger trees in arboriculture, and from the lower cost but slower and less reliable distribution of tree seeds. Trees contribute to their environment over long periods of time by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe. In silviculture the activity is known as reforestation, or afforestation, depending on whether the area being planted has or has not recently been forested.
Envisat was launched as an Earth observation satellite. Its objective was to service the continuity of European Remote-Sensing Satellite missions, providing additional observational parameters to improve environmental studies. In working towards the global and regional objectives of the mission, numerous scientific disciplines currently use the data acquired from the different sensors on the satellite to study such things as atmospheric chemistry, ozone depletion, biological oceanography, ocean temperature and colour, wind waves, hydrology (humidity, floods), agriculture and arboriculture, natural hazards, digital elevation modelling (using interferometry), monitoring of maritime traffic, atmospheric dispersion modelling (pollution), cartography and study of snow and ice.
The Master Arborist examination is a far more extensive exam than the International Society of Arboriculture Certified Arborist Exam, and covers a broad scope of both aboriculture management, science and work practices. Another credential that is on a par with the Master Arborist is that of the American Society of Consulting Arborists, the Registered Consulting Arborist. There are perhaps six hundred individuals with that qualification, and only 70 arborists who hold both credentials. The ISA Board Certified Master Arborist exam covers virtually every area of aboriculture (other than consulting), with the following areas covered on exam.
The mycelia also extended the environment in the soil that the bacteria were able to grow in. An experimental study in Portugal showed that Pinus pinaster trees grew better after being inoculated with mycelium from S. bovinus, Laccaria laccata and Lactarius deterrimus and spores of Pisolithus tinctorius and Scleroderma citrinum. These fungi were proposed as an alternative for chemical fertiliser in arboriculture of pine trees. Suillus bovinus has been shown to improve the tolerance of its host Pinus sylvestris to metal pollutants such as cadmium and zinc, though not to hazardous organic compounds such as m-toluate.
Overburden is also used for all soil and ancillary material above the bedrock horizon in a given area. By analogy, overburden is also used to describe the soil and other material that lies above a specific geologic feature, such as a buried astrobleme, or above an unexcavated site of archeological interest. In particle physics, the overburden of an underground laboratory may be important to shield the facility from cosmic radiation that can interfere with experiments. In arboriculture, the word is also used for the soil over the top of the roots of a tree collected from the wild.
The arborist certification program has successfully improved the profession by setting minimum standards of achievement, incentives for continuing education, and an improved image from both the arborist and the general public points of view. The language used in arboriculture has become more scientific and educated, and less dependent on vague and ambiguous words like lacing and rounding-over. The more descriptive language Certified Arborists use gives purchasers of tree service a high degree of assurance that their trees will not be damaged or mutilated, and that both they and the arborist understand the effects of a particular treatment.
Arboriculture in a mediaeval Islamic manuscript Ibn Bassal worked at the Abbabid court of Al-Mutamid, for whom he created the Hā’īṭ al-Sulṭān botanical garden in Seville. Originally from Toledo, Ibn Bassal moved to Seville after Alfonso VI conquered Toledo in 1085. Crop Protection in Medieval Agriculture: Studies in Pre-modern Organic Agriculture He travelled (on pilgrimage) to the Hejaz, visiting Egypt, Sicily, Syria and seemingly also countries from Abyssinia and Yemen to Iraq, Persia and India. He returned with knowledge of the cultivation of cotton, and he may well have brought seeds and plants with him for the Toledo botanical garden.
Located in the Warwickshire countryside, the Moreton Morrell centre offers courses in equine, farriery and blacksmithing, agriculture, countryside, arboriculture, environment, horticulture, construction, floristry, animal welfare and veterinary nursing. The resources include a 345-hectare commercial farm with a large dairy herd, beef and sheep, wildlife habitats including woodlands, grasslands and wetlands. The College also has equine facilities, with stabling for over 100 horses, an indoor school, a covered school and large outdoor riding arenas. There are 3 forges, purpose-built centres for horticulture and veterinary nursing, as well as a large animal welfare centre housing a wide range of animals and facilities.
In 1886, Jack joined the Arnold Arboretum as a working student under the direction of Professor C. S. Sargent, who recommended Jack's promotion to Lecturer in arboriculture five years later in 1891. During this period, Jack also spent two summers working as an agent of the Geological Survey, and the Department of Agriculture, exploring the forests of Colorado and of the Bighorn Mountains in Wyoming. He went on to serve as an Instructor in Forestry at Harvard, and as Lecturer in Forestry at MIT before appointment as Assistant Professor of Dendrology at the Arnold Arboretum in 1908; he retired in 1935.
In 2011 the college had over 7,000 students, of whom 2,500 were full-time, with about 1,000 studying Higher Education. Subjects to study at Myerscough College include arboriculture, agriculture, ecology, countryside management, motorsports, mechanisation, sports and leisure, golf, landscape design, animal care, equine studies, horticulture, sportsturf, photography, and farriery/metalwork. Short courses for industry range from crane handling to crop spraying, and short leisure courses from caravan manoeuvring to floristry. Myerscough has also been in the forefront of developing on-line and blended learning courses for the land-based industries, allowing students to work full or part-time and to study on-line to complete foundation degree and Honour degree programmes.
They used various measurements developed by the International Society of Arboriculture and the United States Forest Service to formulate a tree risk assessment. At the time of their investigation, the tree's diameter at breast height was , with 27% of the trunk consisting of open space. Hannah and Brashears also found that one-third of the lower trunk and root crown demonstrated callus formation and no new growth, but instead severe decay and peeling bark. Hannah and Brashears further determined that structural mitigation was not feasible, and that the Webster Sycamore was to be "considered an extreme hazard" and the public should be "excluded from its striking zone through fencing and signage".
In 1860, Matthew read in the Gardeners' Chronicle for 3 March a review (by Huxley[T. H. Huxley] (26 December 1859) Darwin on the origin of species, The Times, pp. 8–9), republished from The Times, of Charles Darwin's On the Origin of Species, which said Darwin "professes to have discovered the existence and the modus operandi of natural selection, and described its principles". A letter by Matthew, published in the Gardeners' Chronicle on 7 April, said that this was what he had "published very fully and brought to apply practically to forestry" in Naval Timber and Arboriculture in 1831, as publicised in reviews.
" Patrick Matthew wrote in his book On Naval Timber and Arboriculture (1831) of "continual balancing of life to circumstance. ... [The] progeny of the same parents, under great differences of circumstance, might, in several generations, even become distinct species, incapable of co-reproduction." Darwin implies that he discovered this work after the initial publication of the Origin. In the brief historical sketch that Darwin included in the 3rd edition he says "Unfortunately the view was given by Mr. Matthew very briefly in scattered passages in an Appendix to a work on a different subject ... He clearly saw, however, the full force of the principle of natural selection.
Fellows of the institute bear the postnominals FICFor (Fellow of the Institute of Chartered Foresters) in addition to their designation. Members of the Institute of Chartered Foresters are required to undertake Continuous Professional Development (CPD) and are bound by a Code of Ethics and Professional Conduct. Current membership numbers are over 1,800. The ICF's mission is to raise professional standards in forestry and arboriculture in order to promote the sustainable management of trees and woodlands throughout the UK. A key element of this mission is raising awareness of the issues facing forestry sector professionals and providing guidance to professionals from other sectors and to the public in relation to these issues.
In the upstream basin, the farmers practice farming in dry: arboriculture of olive trees (71% of plantations) and almonds (12%) and cereals dominate this area even though there are also small farms. However, due to the small size of farms - often less than five hectares - and fluctuating climatic conditions, farmers are often forced to seasonal migration to the cities to supplement their incomes. Moreover, apart from in a few municipalities such as El Alâa, Haffouz or Kesra, settlement is scattered, isolated and difficult to access. Crops irrigated are present only on a few places near available water resources because the erosion of soil provides low yields.
The traditional kabyle economy which prevailed until the 19th century was based on a relative poverty of natural resources, combined with a relatively high population density - a contrast which had been noted since the time of Ibn Khaldun. The land was mountainous with little arable space, and agriculture was vulnerable to natural disasters such as drought as well as political events such as armed conflict. This fragile system maintained its viability through specific forms of social organisation, including how land was inherited. While horticulture and arboriculture were key activities however, the poverty of resources meant that there was also a great deal of artisanal and commercial activity in the region.
Considering that through Kaçanik runs the main roadway E65 N2 (European route E65 National 2 also known as E65 M2 European route E65 Main 2 as well as R6 ( Route-6 ) and the name of highway is Arbën Xhaferi connects Pristina and Skopje, and also R116 Regional 116 ( Doganaj-Tetovo) as well as the railway Kosovo Polje-Thessaloniki (constructed in 1879) Kaçanik is a strategic economic focal point. The Kaçanik municipality is known for the production of construction materials at several area companies. There are also many cultivated farmlands and areas suited for the development of farms, apiculture, arboriculture as well as various craftsman and artisans. The area is well suited for the development of winter and summer tourism.
Myerscough College is home to the National Centre for arboriculture, and is recognised internationally for its specialism in this subject. There is an international equine arena, a nine-hole golf course and simulated golf training centre, the plant centre, an off-road driving track, nine-hole disc golf course, sports fields and a sports centre and gymnasium, as well as an arboretum, woods, fields, ponds and the River Brock on the site. The Frank Peregrine Higher Education Centre was opened in 2006 and extended in 2010. In addition, the college houses the Rural Business Centre, which provides support for rural business in the form of courses, advice, links and the Rural Business Incubator for startup businesses.
There were 35 academic staff, and approximately 40 technical, administration and ancillary staff. The University phased out the TAFE courses, in line with the "Melbourne Model". Current courses run at the campus include; Doctor of Philosophy (by research), Master of Philosophy (by research), the Master of Urban Horticulture (course work), the Graduate Certificate in Arboriculture, the Graduate Certificate in Garden Design, the Specialist Certificate in Green Roofs and Walls and the Associate Degree in Urban Horticulture. Burnley College is now much more focused on postgraduate research than in the past, specializing in areas such as green infrastructure, forest science, waterways ecology and management, environmental horticulture and has a significant soil science research group on campus.
William Keane was a 19th-century English gardener and garden writer, whose descriptions of important gardens in Surrey and Middlesex remain a source of historical reference. Keane was the gardener at Orwell Park, Ipswich, and a contributor to the Journal of Horticulture. He wrote five gardening books, first published between 1849 and 1861. His first work was The Beauties of Surrey, published in 1849, described as being "a particular description of about one hundred and twenty seats of the nobility and gentry, in the County of Surrey, comprising all that is interesting in the departments of horticulture, floriculture, arboriculture, park and pleasure ground scenery, from visits made in the spring of 1849".
'Prospector' has featured in several elm trials in the United States, notably those conducted by the Northern Arizona University at Holbrook, eastern Arizona, and Townsend & Douglass Townsend A. M. & Douglass, L. W. Variation among American Elm Clones in Long- term Dieback, Survival, and Growth Response to Ophiostoma Inoculation which established that the tree's survival rate after inoculation with the Dutch elm disease pathogen was 100%. In trials in California, the tree exhibited a singular sensitivity to boron concentrations of > 200 ppm in the soil, causing marginal necrosis on the leaves.Costello, L. R. (2004). A 10-year evaluation of the performance of four elm cultivars in California, U.S. Journal of Arboriculture, March, 2004.
Button established the firm Capital Helicopters in 1975 and made his aircraft available for use in emergencies. He was a witness of the sinking of the inter-island ferry in 1968, and is thought to have had the idea of a rescue helicopter service as a result of this experience. The hilly terrain of Wellington means that helicopters are often used for building and arboriculture work due to the difficulty of site access, which meant that the pilots at Capital Helicopters were particularly skilled in precision flying, and thus suited to rescue work. Thanks to a sponsorship deal in the early eighties Button was able to dedicate one of his helicopters solely to rescues.
See also, refutation by Dagg (2018) alleging that Charles Darwin and Alfred Wallace plagiarised the theory of natural selection from Scottish grain merchant and arboriculturist Patrick Matthew. Matthew had published On Naval Timber and Arboriculture in 1831, twenty-eight years before Darwin's On the Origin of Species. Darwin biographer James Moore declared it a "non-issue", and said that "I would be extremely surprised if there was any new evidence had not been already seen and interpreted in the opposite way.".. Not according to Dagg (2018) Sutton's claim that Darwin and Wallace plagiarised evolution by natural selection from Matthew has been refuted through detailed comparison of the competing theories: ironically, they are too dissimilar to share the same origin.
At the centre of the gardens is the Hamilton Gardens Pavilion, a convention and corporate function centre which can seat 650 people across three rooms. The pavilion also houses the Hamilton Gardens Information Centre, which is run by paid staff and volunteers and offers seasonal plants, tourism bookings and souvenirs. The Waikato Institute of Technology Horticulture Education Centre at Hamilton Gardens offers professional arboriculture, horticulture, floristry, landscape design and horticultural technology courses and holds an annual open day to prospective students. A focal point of Hamilton Gardens is Turtle Lake, an artificial lake and duck habitat with a stage on one side and a walkway running above the water on the other.
Donn, J. 1831 Hortus Cantabrigiensis In 1830 the Duke of Bedford built a new flower market at Covent Garden, and Sinclair took up a tenancy with his partner, John Cormack, in one of the conservatories there. He also had premises at 53, Regent Street. He continued to be busy with his writing, publishing papers for the Quarterly Journal of AgricultureQuarterly Journal of Agriculture, 3 (1832), 976 and the Highland Society of Scotland,Prize-Essays & Transactions of the Highland Society of Scotland, 4 (1832), 31 and with consultancy work on practical and scientific matters that concerned arboriculture, pastures, lawns, and agricultural and horticultural chemistry. He also carried out valuations of woods and plantations.
Botanists commonly differentiate between branches that originate from the initial extension growth and those that have developed epicormically from the growth of latent buds or adventitious buds that developed later on the tree's trunk surface.Harris R. W., Clark J. R. & Matheny N. P. (1999) Arboriculture: Integrated Management of Landscape Trees, Shrubs and Vines; 3rd Edition; Prentice Hall: New Jersey A clear anatomical difference can be found on dissection between these branch attachments, in that the former has an initial knot that originates near to the stem's pith, those developing from latent buds will have a bud trace that originates near the stem's pith, and adventitious epicormic branches will exhibit neither of these internal features.
He also covers arboriculture, detailing the propagation of the palm, olive, pomegranate, quince, apple, fig, pear, cherry, apricot, plum, peach, almond, walnut, hazelnut, grape, citron, orange, pistachio, pine, cypress, chestnut, holm-oak, deciduous oak, tree of paradise, arbutus, elm and ash. He describes manure with straw or sweeping mixed in as mudaf, implying that it is not composed of only one material (animal dung) but is a mixture. The sweepings from hot baths included urine and human wastes, which Ibn Bassal describes as dry and salty, unsuitable for use as fertilizer unless mixed with other types of manure. Ibn Bassal gives two recipes for composting pigeon (hamam) and possibly donkey (himar) manure, though the translation is uncertain.
Writing to Darwin in 1871, Matthew enclosed an article he had written for The Scotsman and, as well as wishing that he had time to write a critique of The Descent of Man, and Selection in Relation to Sex, expressed the belief that there is evidence of design and benevolence in nature, and that beauty cannot be accounted for by natural selection. Such a belief is mainstream natural theology, and reveals how far Matthew was from Darwin in realising the potential of evolutionary explanations: for him as well as others, man was the sticking-point. There is little or no evidence that Matthew held these views as a younger man: there is no discussion of a religious nature in Arboriculture.
Loudon's Arboretum et Fruticetum Britannicum, 8 vols., (1838) is probably the most significant work on the subject in British history and included an account of all trees and shrubs that were hardy in the British climate, an international history of arboriculture, an assessment of the cultural, economic and industrial value of trees and four volumes of plates. Loudon urged that a national arboretum be created and called for arboreta and other systematic collections to be established in public parks, private gardens, country estates and other places. He regarded the Derby Arboretum (1840) as the most important landscape-gardening commission of the latter part of his career because it demonstrated the benefits of a public arboretum (for more details see below).
Harris City Academy Crystal Palace Crystal Palace contains three primary schools, Paxton Primary School, Rockmount Primary School and All Saints C of E Primary School, and one secondary school, Harris City Academy. Crystal Palace Park also contains a branch of Capel Manor College, offering courses in Animal Care, Arboriculture and Countryside, Horticulture and Landscaping and Garden Design along with other short courses. In 2013, due to a shortage of primary school places in both Crystal Palace and London, proposals to open a new primary school by September 2015 were put forward, with plans submitted to the Department for Education in January 2014. The proposals were approved as part of wave 6 of the Free Schools Programme and the school is scheduled to open in September 2015.
8Bagwell, William, Director of Agronomy, Callawassie Island, International Society of Arboriculture Certified Arborist Despite the amount of surrounding salt water, Callawassie Island has thirty-three fresh water, man-made lagoons covering . In addition to providing irrigation water for the golf course, these same lagoons enhance the ecology of the island and the surrounding waters by reducing the rainwater run-off into the marsh and providing a source of food for alligators and fish-eating birds. Callawassie has a long history of human occupation. Indians used the surrounding waters for shell fishing and portions of the adjacent land for cultivation. Approximately 275 years ago, Europeans began to significantly impact the ecology of the island primarily through logging most of the pine trees from the interior of the island and later by farming the land.
The Master Arborist or Board Certified Master Arborist credential identifies professional arborists who have attained the highest level of aboriculture offered by the International Society of Arboriculture(ISA) and one of the two top levels in the field. There are several paths to the Board Certified Master Arborist, but typically on average each has been an ISA Certified Arborist a minimum of three to five years before qualifying for the exam (this can vary depending upon other education and experience). The certification began as a result of the need to distinguish the top few arborists and allow others to identify those with superior credentials. The ISA added specialty certifications of Utility Specialist, for those maintaining vegetation around electric utility wires, Municipal Specialist, for those with additional experience managing public urban trees.
Hockeridge Woods in early autumn The Society has 20 Divisions which between them organise up to 100 woodland field meetings a year on topics that span seed to sawmill. Annually: a top-level conference is held; there is a 4 or 5 day woodland study tour in England, Wales or Northern Ireland; Excellence in Forestry Awards take place, there is a travel bursary for forestry study abroad, and workshops, seminars and knowledge transfer events. Overseas study tours are held every other year. The RFS helps shape formal forestry qualifications and its own Certificate of Arboriculture is recognised across the sector; it encourages students with a range of awards, bursaries and internships; has launched a research programme with colleges and has partnered with a number of organisations to help share knowledge.
The Hutchisons had long-standing and successful trade connections in the port town of Leith and had risen to prominence as a result of their success. Robert Hutchison, Thomas's heir responsible for completing the castle, was a fellow of the Royal Society of Edinburgh and an expert in arboriculture, leaving the wine trade behind. Two of his sons were knighted for their contributions to the realm: Sir Robert Hutchison, First Baronet of Thurle in Streatly in the County of Berkshire, a respected medical authority and the President of the Royal College of Physicians and Sir Thomas Hutchison, Lord Provost of Edinburgh, First Baronet of Hardiston in the County of Kinross, who held the office from 1921–1923. Robert's niece was the renowned Arctic explorer and botanist Isobel Wylie Hutchison.
In 2017, cacao residues in ten vessels from the site, all Preclassic in style, were identified at the Hershey Company laboratory,(Kaplan et al. 2017) lending greater weight to the theory that cacao arboriculture existed at Chocolá early in the trajectory of Maya civilization. If Chocolá grew cacao intensively, it likely would have traded this commodity, so highly valued by the ancient Maya and other ancient Mesoamerican cultures. Given the long-standing accumulation of evidence of high or advanced hallmark traits of Maya civilization - writing, the stela-altar complex and "kingship," the Maya calendar - appearing first in the Southern Maya Region, PACH investigators have proposed a material basis for the emergence of at least some of these traits, based on the discovery of the sophisticated water management system and of possible cacao cultivation and trade.

He was also a trustee and chairman of the Agricultural College at Amherst (now the University of Massachusetts Amherst), as well as commissioner of public parks in Worcester. Hadwen bequeathed his arboretum to Clark University for the sole purpose of education, with the following words: "Said estate to be forever kept for the purpose of educating students in Agricultural, Historical, and Arboreal knowledge scientific and practical. I adopt this course with the purpose in view of preserving the trees and plants growing thereon, being a portion of my life work, shall be preserved as an Arboretum, and an object lesson to assist students in the education of the science and art of Arboriculture and improving the landscape." He also willed $1000 to Clark University to be invested, with the annual income used "to embellish the University grounds with ornamental trees and plants".
A whoopie sling for hammock camping A whoopie sling is an easily adjustable rope sling designed for tree pruning or tree removal.Tree Care Industry, Volume 11, National Arborist Association, 2000 - ArboricultureEvaluation of current rigging and dismantling practices used in arboriculture, page 79 The whoopie sling works by wrapping the sling around the trunk of a tree or a heavy load bearing limb and pulling the end of the rope within the sling through a spliced choker. By adjusting the size of the eye in the rope through the choker the user is able to adjust the length of the sling constricting around the tree without needing knots. It is also becoming more common (usually in smaller diameter) for suspending hammocksDerek J. Hansen: The Ultimate Hang (An Illustrated Guide To Hammock Camping), 2011, during hiking, camping, or sailing.
Medieval Islamic arboriculture: Ibn Bassal and Abū l-Khayr al- Ishbīlī described in detail how to propagate and care for trees such as olive and date palm. The first Arabic book on agronomy to reach al-Andalus, in the 10th century, was Ibn Wahshiyya's al-Filahat al-nabatiyya (Nabatean Agriculture), from Iraq; it was followed by texts written in al-Andalus, such as the Mukhtasar kitab al-filaha (Abridged Book of Agriculture) by Al-Zahrawi (Abulcasis) from Cordoba, around 1000 AD. The eleventh century agronomist Ibn Bassal of Toledo described 177 species in his Dīwān al-filāha (The Court of Agriculture). Ibn Bassal had travelled widely across the Islamic world, returning with a detailed knowledge of agronomy. His practical and systematic book both gives detailed descriptions of useful plants including leaf and root vegetables, herbs, spices and trees, and explains how to propagate and care for them.
Caussade depended on the election and stewardship of Montauban and the parliament of Toulouse. Contrasting with the slow erasure of Haut-Quercy, the last two centuries of the Ancien Régime are the economic heyday of this prosperous southern area, diversified agriculture, viticulture and arboriculture refined the remarkable industrial dynamics, driven by textile and mills. In the seventeenth and eighteenth century, Bordeaux's proximity began to touch the valleys of the Quercy. Old polyculture here and there supplemented by dyeing and textile crops, declines. Industrial crops regress in 1830, apart from tobacco . After 1850, fruit and vegetable crops characterise the country of the Garonne. Until 1900, rail encouraged the production and export of tomatoes, peas, beans, onions, asparagus and cauliflower plus artichokes and melons in a few areas. After the crises of the vine by phylloxera between 1880 and 1900, fruit crops were grown, especially plums, cherries and table grapes.
By the mid-1960s the tree was in severe decline, leading to successive die-off of the treetop, until the water table began to recover in the late 1990s. Efforts to restore the tree's health by the Southern Pacific Railroad, the City of Palo Alto and local citizens included progressive pruning of the dying treetop, addition of soil and mulch at the tree’s base, removal of dead limbs, pesticide spraying and installation of a pipe up its trunk to bring water to mist the top of the tree. Although the tree stands today at only 68% of its former stature, it enjoys greater health than nearly a century ago. A 1999 horticultural appraisal of El Palo Alto, conducted in accordance with the Guide for Plant Appraisal authored by the Council of Tree and Landscape Appraisers and published by the International Society of Arboriculture, valued the tree at $55,600.00.
Straight Boom Lift with telescopic boom extended and rough terrain tyres, Duralift Access Hire in Melbourne Another type of aerial device is a straight boom lift or telescopic boom lift, which as its name suggests has a boom that extends straight out for direct diagonal or vertical reach by the use of telescoping sections, letting you take full advantage of the boom length range. Some AWPS are classified as spider lifts due to the appearance of their legs as they unfold, extend and stabilise, providing a wide supportive base to operate safely. These legs can be manual or hydraulic (usually depending on size and price of the machine). AWPs are widely used for maintenance and construction of all types, including extensively in the power and telecommunications industries to service overhead lines, and in arboriculture to provide an independent work platform on difficult or dangerous trees.
Kabylie tribes After ten years of Islamic studies in Great Kabylie, Mohamed Seghir Boushaki settled in his village "Thala Oufella (Soumâa)" in 1891 and began to work in agriculture and commerce. He specializes in carob tree arboriculture by weaving a professional carob bean harvesting network for sale in the state and for processing into locust bean gum and carob bean molasses. He soon gained notable profits which allowed him to rent a house in the French colony of Ménerville (Thénia) bordering "Oued Arbia" in which he married in 1898 at the age of 29 with Fatma Cherifi, daughter of a rich family residing in Sidi Daoud along the Sebaou River. Mohamed Seghir assiduously transformed the mesh of collection of carob bean in Kabylie into a network of inter-village alliances by marriage in the former Algiers Department regrouping the current wilayas of Algiers, Boumerdes, Tizi Ouzou, Bouira, Blida and Tipaza.
Prior to the 1960s urban trees were managed on a tree-by-tree basis. The Dutch Elm Disease finally convinced forest pathologists at the school to consider the urban forest on a systems level, where small changes can create forest-wide effects if not properly managed. In 1962 this thinking gave Jorgensen a convincing enough argument to secure funding for the world’s first “Shade Tree Research Laboratory” in an old dairy plant that the university owned. By 1965 the University of Toronto had its first official urban forestry course, called “the Study of Urban Forestry”, taught by Dr. Jorgensen. Only one year later department head, Dean Sisam, applied the term to the previously known courses of “arboriculture and parks management”, three years following that the university began creating diplomas for urban forestry; producing seven graduates by 1982. The University of Toronto’s program has continued and has grown significantly into current times, inspiring many other institutions to offer a similar diploma as the discipline diffused across the globe.
The exfoliating bark of the Paperbark Maple Acer griseum Exfoliation (from the term "foliate", meaning “related to leaves”) means the removal or loss of leaves from a plant. It is used both to describe the loss of a leaves as a natural part of a plant's life cycle (such as in the case of deciduous trees which lose their leaves in the autumn) or because of some trauma or outside cause (such as dehydration, an infestation of caterpillars or hurricane-force winds). In arboriculture, the term “exfoliating bark” describes the natural process and condition of the bark peeling-away from a tree trunk, typically in large pieces that remain partially attached to the trunk until such time as they are completely detached by the elements or the eventual and subsequent exfoliation of additional layers of bark. Examples of trees with exfoliating bark are the paperbark maple and various species of Plane (Sycamore) and birch.
Since the unification of Italy in 1861, a wide and increasing economic divide has been growing between the northern provinces and the southern half of the Italian state. This gap was mainly induced by the region-specific policies selected by the Piedmontese elite, who dominated the first post-unitary governments, and that more heavily penalized the regions farther away from the rulers’ fiercer enemies, as recently confirmed by Guilherme de Oliveira and Carmine Guerriero. To illustrate, the 1887 protectionist reform, instead of safeguarding the arboriculture sectors crushed by 1880s fall in prices, shielded the Po Valley wheat breeding and those Northern textile and manufacturing industries that had survived the liberal years thanks to state intervention. While indeed the former dominated the allocation of military clothing contracts, the latter monopolized both coal mining permits and public contracts. A similar logic guided the assignment of monopoly rights in the steamboat construction and navigation sectors and, above all, the public spending in the railway sector, which represented 53% of the 1861-1911 total.
Slater, D. and Ennos, A. R. (2015) The level of occlusion of included bark affects the strength of bifurcations in hazel (Corylus avellana L.) Journal of Arboriculture and Urban Forestry 41 (4): 194-207 Common tree care practices are to prune out such bark-included forks at an early stage of the tree's development, to brace the two arising branches above such a junction so that they can not split apart (using a flexible brace) or to reduce the length of the smaller arising branch, so that it is subordinated to the larger branch.Gilman E. F. (2012) Illustrated guide to pruning; third edition; Delmar publishers, Albany, NY. Care should be taken not to prune out 'natural braces' set above weak tree forks in mature trees unless that is absolutely necessary.Slater D.(2016) Assessment of Tree Forks; Arboricultural Association, Stroud, UK. An included bark junction formed in a wild cherry tree (Prunus avium) The strength of a normally-formed tree fork can be assessed by its shape and the presence and location of axillary wood: those that are more U-shaped are typically considerably stronger than those that are V-shaped at their apex.
He became an avid proponent as well as interested researcher of both silviculture and horticulture, both of which influenced his growing awareness of the forces of nature. This awareness, along with his own experiences acquired from years of working his own modest estate would later frame a strong base of reference to form his own opinions and theories.Calman, WT (1912) "Patrick Matthew of Gourdiehill, Naturalist", Handbook and Guide to Dundee and District, AW Paton and AH Millar (Eds), the British Association for the Advancement of Science, pp. 451-7 (see The Patrick Matthew Project » More On Matthew Between 1807 and 1831 (when On Naval Timber and Arboriculture was published) he periodically travelled to Europe, sometimes on business, sometimes seeking scientific enlightenment or agricultural or economic advice: a trip to Paris in 1815 had to be cut short when Napoleon returned from Elba. Between 1840 and 1850, Matthew travelled extensively in what is now northern Germany; recognising the commercial potential of Hamburg he bought two farms in Schleswig-Holstein. Matthew married his maternal first cousin, Christian Nicol in 1817, and they had eight children: John (born 1818), Robert (1820), Alexander (1821), Charles (1824), Euphemia (1826), Agnes (1828), James Edward (1830), and Helen Amelia (1833).
