Rock firefinches prefer inselbergs in bush savannah habitats and rocky outputs to build their nests in. Inselbergs are isolated hills or mountains that arise from a flat plain. Regardless of the season, rock firefinches live in inselbergs and avoid farmland areas. Rock firefinches have high site fidelity, habitually returning to the same area throughout the whole year.

In some locations this saprolite reaches thicknesses of about . The development of this weathering is attributed to the humid climate and to stable conditions with limited amounts of erosion. Where the batholith-derived saprolite is eroded, inselbergs, such as El Peñón de Guatapé, crop out. Inselbergs correspond to rock masses of the batholith that resisted weathering and erosion by being less fractured.

In general, the landscape of the interior is undulating land with occasional inselbergs jutting out dramatically from the surrounding rolling landscape. Some include: Okeagbe hills: 790m, Olosunta in Ikere Ekiti: 690m, Shaki inselbergs, and Igbeti hill. With coastal plains, southern lowlands, and interior highlands, Yorubaland has several large rivers and streams that crisscross the terrain. These rivers flow in two general directions within the Yoruba country; southwards into the lagoons and creeks which empty into the Atlantic ocean, and northwards into the Niger river.

Therefore, rocky substrates provide moisture in the habitat, so long as there is not appreciable runoff from the rock surfaces and there is plenty of accumulated fine soil in the cracks, which, in turn, retains water. In these conditions, Pachypodiums can store enough water in their trunks to easily withstand a dry period of five or more months. Inselbergs are quite common in Angola extending into Namibia, Zimbabwe, and western Madagascar. Inselbergs have been demonstrated to support a plant community dramatically different from their surroundings (Rapanarivo,1999a).

Sugarloaf Mountain, a non-inselberg bornhardt in Rio de Janeiro, Brazil Kata Tjuṯa, in Northern Territory, Australia A bornhardt () is a dome-shaped, steep-sided, bald rock outcropping at least in height and several hundred metres in width. They are named after Wilhelm Bornhardt (1864–1946), a German geologist and explorer of German East Africa, who first described the feature. While bornhardt was originally used to sometimes denote a type of inselberg, the term bornhardt is used in modern literature to refer to domed hills and mountains regardless of isolation in the landscape; thus, not all bornhardts are inselbergs and not all inselbergs are bornhardts. Bornhardts are commonly composed of igneous rocks, for example granites.

View of the town of Jokkmokk located amidst the Muddus plains. Note the residual hill or inselberg in the background. The Muddus plains is a landscape type in northern Sweden characterized by its flat topography dotted with inselbergs. The topographic character of the Muddus plains was first described in detail by Walter Wråk in 1908.
|
|
When the land surface, which is underlain by deeply weathered bedrock, around an inselberg is lowered by erosion, the pocket of deeply weathered disaggregated bedrock is also removed to produce a flared slope such as Wave Rock. It has also been argued that flared slopes can form during the erosion of slopes of any inselbergs.

These birds have the ear coverts and hind brow marked in yellow, as opposed to the dusky-headed populations. The type was obtained from oNgoye Forest in South Africa, and named for its discoverers, the Woodward brothers. S. o. belcheri, which lacks the yellow ear coverts, is endemic to two isolated inselbergs, and may constitute a third species.

The marbled rubber frog (Phrynomantis annectens) is a species of frog in the family Microhylidae. It is found in Angola, Namibia, and South Africa. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, intermittent freshwater marshes, hot deserts, and temperate desert. Its survival often depends on finding deeper pools in inselbergs and other rocky formations.

What little is known about seed dispersal of Pachypodium supports a scattering effect confined to sets of outcrops and inselberg landscapes. Pachypodium seed dispersal is carried out by wind, suggesting the scattering target as outcrops and inselbergs. Yet, according to Rapanarivo et al., this type of dispersal might not be the best method for the genus.

Though black-chested prinias are not thought to be migratory, there is evidence that they may be locally nomadic. Herremans found that black-chested prinias expand their range during severe droughts, becoming a bit nomadic in order to adapt to challenging environmental conditions. Kopij noticed a seasonal decrease in the local populations of black-chested prinias in “inselbergs,” bushy isolated hills within dry grasslands.

Additionally, it often found near inselbergs and a source of water, either a river or a forest pool. The understory of its forests has sparse undergrowth or open spaces but is covered in mosses, ferns, lianas, and epiphytes. In southwestern Bioko it is found in low forests that receive nearly of rain a year. Bioko's habitat also has dense undergrowth and vertical gorges near a caldera.

Spriggs, A. 2001.(AT0709) The Karoo apparently does not experience drought on a regular basis, so even though the area is technically desert, regular winter rains provide enough moisture to support the region’s interesting plant community. Another feature of the Kalahari, indeed many parts of Namibia, are inselbergs, isolated mountains that create microclimates and habitat for organisms not adapted to life in the surrounding desert matrix.

Landscapes formed by erosion in hardned ignimbrite can be remarkably similar to those formed on granitic rocks. In Sierra de Lihuel Calel, La Pampa Province, Argentina, various landforms typical of granites can be observed in ignimbrite. These landforms are inselbergs, flared slopes, domes, nubbins, tors, tafonis and gnammas. In addition, just like in granite landscapes landforms in ignimbrites may be influenced by joint systems.

On outcrops, steep hills, and inselbergs, the plants are subjected to fluctuating moisture, high winds, and temperature extremes. Only plants with special adaptations to exposure and extreme drought can survive, let alone thrive, on these exposed geological habitats. Pachypodium root in cleft, fissures, and crevices of those rocky formations. The non-succulent roots penetrate deeply into the acuminated soil, mineral, and humus in these crevices.

On outcrops and inselbergs, Pachypodium species root in the clefts, fissures, and crevices of these rocky formations. The non-succulent roots penetrate deeply into the accumulated soil and humus in these crevices. On these geological formations, cracks in the rocks will fill quickly with water that can penetrate quite deeply. Under these conditions, there is very little evaporation so that almost all the collected water remains.

Even larger examples are known from Sweden where they are referred to as flyggbergs. The Swedish flyggbergs have been interpreted by Sten Rudberg and others as reshaped inselbergs. Ice-smoothed bedrock bumps which lack the steep, plucked lee side faces are referred to as whalebacks or rock drumlins. Prest (1983) specifies a distinction between a glaciated "roches moutonnées surface" and a simple "stoss and lee" glacial feature.

The country between Malawi and Ibo is remarkable for the number of fantastically- shaped granite peaks, or inselbergs, which rise from the plateau. The plateau lands west of the escarpment are of moderate elevation - perhaps averaging It is, however, only along the Zambezi and north of that river that Mozambique's territory reaches to the continental plateau. This northern plain has been categorised by the World Wildlife Fund as part of the Eastern miombo woodlands ecoregion.

The Neptune Islands were formed between 10800 and 12000 years ago when sea levels rose at the start of the Holocene. The islands are remnant igneous inselbergs which have survived the erosive process associated with sea level rise. The remnant rock is described as being "a porphyritic granite gneiss and pink granite intruded with dolerite dykes". Remnants of the once-overlying calcarenite layers are also present on the upper platforms of the island.

The Diamaré Plain occupies the lower third of the Chad plain and is characterised by a number of isolated inselbergs. The Mandara Mountains at the southwestern border with Nigeria form the highest point, lying between 500 and 1000 metres, with an average of about 900 metres. Mount Tourou is the highest point, at 1,442 metres. These mountains likely arose as a result of the same tectonic activity that gave rise to the Bénoué Depression in the North Province.

This deformation is an isostatic response to erosion and the load of Phanerozoic sediments that rests above much of the peneplain. The peneplain is characterized by a general lack of inselbergs. One exception to this is the island Blå Jungfrun in the Baltic Sea which is an ancient inselberg formed in Precambrian time and buried in sandstone after its formation. Blå Jungfrun remained buried until erosion of the East European Platform freed it in geologically recent times.

The developing plant roots are associated with mineral-weathering mycorrhizal fungi that assist in breaking up the porous lava, and by these means organic matter and a finer mineral soil accumulate with time. Such initial stages of soil development have been described on volcanoes, inselbergs, and glacial moraines. How soil formation proceeds is influenced by at least five classic factors that are intertwined in the evolution of a soil. They are: parent material, climate, topography (relief), organisms, and time.

Tricarpelema africanum is a monocotyledonous flowering plant in the dayflower family. It is native to west-central Africa and is typically found growing in shallow soils on inselbergs. The species is the only member of its genus not found in the moist forests of tropical Asia and the only species of the subgenus Keatingia. Tricarpelema africanum's physical separation from its Asian relatives has led it to evolve a number of unique morphological features, most of which are vegetative adaptations to drier conditions.

Together with other kinds of erosion such as frost and salt weathering, these have formed a pediplain terrain with inselbergs being left, especially where harder rocks are found. Pebbles eroded from Bazman have been transported to the terrains of the Jaz Murian depression south of Bazman. The effects of this erosion have mantled the volcano with debris locally known as "dasht", reaching distances of over from the vent. With the exception of the Ziyarat valley on Bazman's southern flank, the area around Bazman is arid and uninhabited.

A granite outcrop in the Stirling Range National Park Granite outcrops of Western Australia are weathered landforms that occur throughout the state of Western Australia, composed primarily of the rock type granite. All recognised types of this landform can be observed, commonly as bornhardts, but also as inselbergs, castle koppies and Nubbins. Rising abruptly from the surrounding landscape they create a variety of microhabitats for plants, and provide seasonal resources and refuge for a range of animals. These areas thus have rich biodiversity and many endemic species.

The flowers of these orchids resemble those of Laelia, but the main difference between these two genera lies in the vegetative part. These orchids occur exclusively in Eastern Brazil, often as epiphytes. Some are lithophytes, forming a thicket on the rocks. Others, as Pseudolaelia vellozicola, are semi-epiphytes and can be found on mat-like communities of Vellozia bushes on inselbergs (dome-shaped granitic or gneissic rock outcrops) in the Brazilian Atlantic rainforest, requiring an adaptation to the extreme environmental conditions (dryness, isolation) The rhizomes are extended.

The topography of the area is undulating and slopes ranging from 200 metres to 300 metres are found in the western and northern part of the district particularly. In the valleys of Kulpawn, Besibeli, Asibelika and the Azimzim, the slopes are gentler and range from 150 metres to 200 metres. Inselbergs and other granitic outcrops occasionally break the monotony of the near flat surfaces. In general the low-lying nature of the land makes greater part of it liable to flooding in years of copious rains.

The main plateau of the central part of the island, which was once the sea bottom of the ancient Iapetus Ocean, has been heavily eroded by water and ice. Steep, solitary rock knobs, called "tolts" in Newfoundland (elsewhere known as inselbergs or monadnocks), which jut or more above the generally flat terrain are the remnants of a former higher landscape level. Glaciers which helped shape these tolts left other evidence around Newfoundland. Large blocks of stone called glacial erratics have been left scattered across much of the landscape.

The Cottaer Spitzberg was formed as a result of the Tertiary breakthrough of basalt through the Cretaceous sandstone sediments of the Elbe Sandstone Mountains. In geological region that is composed largely of sandstone, granite and gneiss the hill is very much a geological exception. Basalt cone at the summit The hill is one of a line of volcanic inselbergs of which the Stolpener Burgberg, the Wilisch and the Geising are the best-known. On the rocky summit of the Spitzberg, the grey and black columns of the trachyte basalt are exposed.

In Eurasia, fresh or brackish waters may be inhabited and the pelicans may be found in lakes, deltas, lagoons and marshes, usually with dense reed beds nearby for nesting purposes. Additionally, sedentary populations are found year-round in Africa, south of the Sahara Desert although these are patchy. In Africa, great white pelicans occur mainly around freshwater and alkaline lakes and may also be found in coastal, estuarine areas. Beyond reed beds, African pelicans have nested on inselbergs and flat inshore islands off of Banc d'Arguin National Park.

Subsequent uplift and erosion of the New England Fold Belt has seen the majority of the surrounding sediments and metamorphic rocks eroded away, with the Stanthorpe Adamellite remaining due to its resistance to weathering. This regolith has created a landscape with many exposed inselbergs of granite rocks, some balancing on top of each other, or forming natural arches. Just off the main road from Tenterfield to the park is Thunderbolt's Hideout, a set of caves and overhanging granite rocks. It was thought to have been used by bushranger Captain Thunderbolt.

Missouri Botanical Garden, St. Louis, U.S.A. & Antananarivo, Madagascar Accessed: February, 2018 The rather conspicuous plant was collected for the first time in 1947 by the French botanist Jean-Henri Humbert, but remained unrecognized in the herbarium of the Musée d´Histoire Naturelle in Paris. Later in 1996 Barthlottia was finally described by the German botanist Eberhard Fischer as a new genus and species. It was named in honor of the botanist and biomimetics scientist Wilhelm Barthlott, who had been interested in the Vegetation of the Inselbergs of Madagascar.Fischer, E., Theisen, I. (2000).

The Kamiesberg or Kamiesberge (Khoikhoi "Th'amies" = "jumble"), is a mountain range of jumbled granite inselbergs or bornhardts dotted over sandy plains and centered on Kamieskroon in Namaqualand in South Africa. This range is very like the Matopos of Zimbabwe in appearance. It stretches for about 140 km (60 mi) from Garies in the south to Springbok in the north and forms a plateau between the Sandveld of the Cape West Coast and Bushmanland in the east, with the Hardveld of the mountainous central Kamiesberg escarpment in the midst.

Rocky Inselbergs: typical habitat of rock firefinches It was first believed that rock firefinches were only endemic to the Jos Plateau in central Nigeria, but observations were also reported in northern Cameroon, which borders eastern Nigeria. Rock firefinches are considered to be range-restricted, since they are mostly found in the Jos Plateau. The Jos Plateau is a rocky habitat with a semi-temperate climate with temperatures ranging from 60-80 degrees Fahrenheit. There is a distinct dry season from November to April and rainy season from May to October.

Contrary to the glacial and periglacial hypotheses, Julius Büdel and Jean-Pierre Peulvast regard weathering of rock into saprolite as important in shaping the strandflat. Büdel held that weathering took place in a distant past with tropical and sub-tropical climates, while Peulvast considered that present-day conditions and a lack of glaciation were enough to produce the weathering. As such, Peulvast considered the saprolite found in the strandflat, and the weathering that produced it, to predate the Last glacial period and possibly the Quaternary glaciations. For Büdel, the strandflat was a surface shaped by weathering dotted with inselbergs.

Bere researched many inselbergs, the Imatong range on the Sudanese border and the Virunga volcano. In 1955 he became Director and Chief Ranger of the Uganda National Parks. In 1960 he left Uganda with his wife Anne Maree, whom he had married in Uganda in 1936, and lived in retirement at West Cottage near Bude in Cornwall. Bere published about a dozen books including The Way to the Mountains of the Moon (1966), Antelopes (1970), The Nature Of Cornwall (1982) and his autobiography A Cuckoo's Parting Cry: a personal account of life and work in Uganda between 1930 and 1960 (1990).

Boonoo Boonoo NP. The etymology of Boonoo Boonoo is Aboriginal for "poor country with no animals to provide food" and is pronounced 'bunna bunoo'. The local geography is dominated by prominent granite inselbergs and mountains, a fine example being that of the nearby Bald Rock, the largest granite inselberg in Australia, which is located within Bald Rock National Park. The average elevation throughout the area differs from below 600 metres to over 1,100 metres. The main geographic features in the locality are Boonoo Boonoo National Park, Boonoo Boonoo River and Falls, Basket Swamp National Park, Bald Rock National Park and Mount Lindesay Road.

A flared slope is a concave-upward or -inward bedrock surface that is typically found around the base of inselbergs, bornhardts, and granitic boulders and also on their higher slopes. Flared slopes like Wave Rock are particularly well developed in granitic landforms of south-western and southern Australia. The flared slopes are argued to have formed by the concentrated chemical weathering around the base of an inselberg by groundwater. The chemical weathering of the bedrock by groundwater produces a concave-upward or –inward pocket of deeply weathered, relatively loose, and disaggregated bedrock within the formerly solid bedrock base of an inselberg.

The region is characterised by high, isolated inselbergs and kopjes (the Afrikaans term for rocky outcrops), made up of dramatic blood red granites, rich in feldspars and sandstone. The easternmost part of the park covers the Naukluft Mountains. More moisture comes in as a fog off the Atlantic Ocean than falls as rain, with the average 106 millimeters of rainfall per year concentrated in the months of February and April. The winds that bring in the fog are also responsible for creating the park's towering sand dunes, whose burnt orange color is a sign of their age.

Sugarloaf Mountain and the other inselbergs of Rio de Janeiro are the onshore representatives of the basement of the Santos Basin. The basement of the Santos Basin is composed of granites and gneisses of the Araçuarí Belt that formed at the western boundary of the Congo Craton. The erosion resistant metamorphic and magmatic rocks are exposed in the Serra do Mar, forming the edge of the Santos Basin along the Brazilian coast. The total stratigraphic thickness of the sediments in the Santos Basin has been estimated at and has been described in detail by Clemente in 2013.

Many of the most distinctive peaks such as Suilven were formed during the last Ice Age, when they were left exposed above the ice sheet as nunataks, and they now remain as inselbergs of highly eroded Torridonian sandstone sitting on a bedrock of much older Lewisian gneiss. The Moine Thrust runs through the area, and is most visible at Knockan Crag National Nature Reserve, which includes a visitor centre interpreting the geological features of the landscape. In the east of Assynt lies a region of limestone scenery surrounding Ben More Assynt. This part of Assynt hosts the longest cave in Scotland, Uamh an Claonaite, which lies south of Inchnadamph.

Erosion of etchplains can result in the exposure of inselbergs such as bornhardt and tors. Generally the topography exposed at a stripped etchplain, that is an etch surface, after erosion of regolith is one with many irregularities as result of structurally defined areas of rock strength. A distinction can be made between etchplains and etch surfaces as the later may or may not be flat and can represent the landform arising from the stripping of an etchplain. As climate changes arid and semi-arid periods of pediplanation may alternate with more humid periods of etchplanation resulting in the formation of flattish surfaces (peneplains) of mixed origin (polygenetic).

São José de Espinharas is a town in the state of Paraíba, Northeastern Brazil. Located on the banks of the lower Espinharas River, about 30 km to the North of Patos, this small town has its economy based on extensive cattle and goat raising and subsistence agriculture. Its relief is somewhat irregular, with large igneous rock outcrops and small mountains and granite inselbergs. The soil is generally poor ("tabuleiros") and covered by the caatinga vegetation, insterspersed with small valleys ("baixios") with fertile soils that support agricultural activities and are propicious to the building of small and medium-sized dams that store rain-water flowing in temporary creeks.

Panorama of the Rock Arch and Spitzkoppe in the background Panorama of Spitzkoppe and the mountains around The vast campsite at the foot of Spitzkoppe The Spitzkoppe (from German for "pointed dome"; also referred to as Spitzkop, Groot Spitzkop, or the "Matterhorn of Namibia") is a group of bald granite peaks or inselbergs located between Usakos and Swakopmund in the Namib desert of Namibia. The granite is more than 120 million years old and the highest outcrop rises about above sea level. The peaks stand out dramatically from the flat surrounding plains. The highest peak is about above the floor of the desert below.

Stretching for , the river provides water for species such as the rare desert elephant, as well as giraffe, mountain zebra and the largest population of free-roaming black rhinoceroses in the world. The Ugab Wilderness Area was established here to protect the future of these rare animals. Important tourism destinations are the Brandberg, the Doros Crater and Vingerklip, settlements in its catchment area are the towns of Outjo and Otjiwarongo, as well as the settlements of Kalkfeld, Omatjette and Uis. People can trek the length of the sandy river, passing local Herero farmers and the pink granite inselbergs (isolated rocky hills left behind after volcanic activity) dotted throughout the region.

The mountain chain's highest summits are mostly concentrated in an area (of mean altitude of over 1,000 m) between Stavanger and Trondheim in South Norway, with numerous peaks over 1,300 m and some peaks over 2,000 m. Around Trondheim Fjord, peaks decrease in altitude to about 400–500 m rising again to heights in excess of 1,900 m further north in Swedish Lapland and nearby areas of Norway. The southern part of the mountain range contains the highest mountain of Northern Europe, Galdhøpiggen at almost 2,500 m. This part of the mountain chain is also broader and contains a series of plateaux and gently undulating surfaces that hosts scattered inselbergs.

In the western part of the territory, this littoral plain is interrupted by inselbergs, ridges reaching that can reach 200m in height, typical of the riverside land of Bas- Saint-Laurent In the Quaternary, the region was marked by glaciation. the Wisconsin glaciation caused the crust to sink by in the vicinity of Rimouski. When the end of the glaciation started in 18,000 BP, it opened a sound in the Saint-Laurent valley, isolating the glacier covering Bas-Saint-Laurent from the one covering Côte-Nord. The isostatic rebound created an inland sea, the Sea of Goldthwait, which flooded the region under at most 200m of water in the area around Rimouski.

Pachypodium habitats consist of isolated, specialized, micro-environmental niches, generally xeric, rocky, frost-free areas within parts of western Madagascar and southern Africa. Pachypodium species are often indifferent to the regional ecological, biotic zone of vegetation, a fact which explains some of Pachypodium morphology and architecture. The large scale vegetation zones are in some cases irrelevant to the micro-environments of Pachypodium, in the sense that the xeric niches may be embedded in larger mesic biomes. Most Pachypodium are rupicolous species occur on rocky outcrops, steep hills, and on inselbergs or kopjes, land or rocky masses which have resisted erosion and stand isolated in level or gently sloping terrain, sometimes above a forest canopy.

Rocky outcrops, steep hills, and inselbergs create microclimate conditions that may be different from the general climate of a region. The habitats of Pachypodium are thought of as arid ecological, even when they occur in prehumid zonobiomes, because the taxon's topographic position and microclimate conditions differ significantly from the context of the greater ecological conditions within the landscape. The prehumid zonobiomes are humid zones of regional biotic community characterized chiefly by the dominant forms of plant life and prevailing climate, such as forests or mountains. On these ecological islands the flora significantly differs from the greater surrounding zones of vegetation, where a smaller immediate area under the influence of a micro-environmental condition is defined.

The Hundred of Condada is a cadastral unit of hundred located on the northern Eyre Peninsula of South Australia spanning the township of Minnipa and surrounds. One of the 24 hundreds of the County of Robinson, it was proclaimed in 1913 by Governor Day Bosanquet and named for Condada Hill, in the southwest of the hundred. The hundred is entirely spanned by the bounded locality of Minnipa, along with the adjacent hundreds of Pildappa to the east, Carinato the south, and most of the Hundred of Minnipa to the southeast (in which the actual township of Minnipa lies). The hundred is located in the centre of a vast low-rainfall wheat belt and the surrounding countryside is gently undulating but broken by numerous wave-shaped granite outcrops (inselbergs).

In a semi-desert landscape, lawns and trees planted when the town was established accentuate the sense of ‘oasis’ and one of the town’s principal attractions is its golf course. The town’s water wants are greater than could be supplied by any nearby springs, however, and all is kept green by water pumped up from the Orange River some 40 km to the north. But beyond the edges of town the arid conditions and the unique ecologies on the various inselbergs, peaks, hills and plains, with their varied rocky and shallow soil substrate, support a wide range of plants, animals, birds and insects, including rare and endemic species. The writer William Charles Scully wrote that, “for sheer uncompromising aridity, for stark grotesque naked horror, these mountains stand probably unsurpassed on the face of the globe.”Cited by William Dicey, Borderline, p 167.
