Creosote bush is most common on the well-drained soils of alluvial fans and flats. In parts of its range, it may cover large areas in practically pure stands, though it usually occurs in association with Ambrosia dumosa (burro bush or bur-sage). Chemicals found in creosote bush roots have been shown to inhibit the growth of burro bush roots, but as of 2013, much of their relationship remains unexplained. Creosote bush stands tend to display an evenly spaced distribution of plants.

Creosote bush scrub is a North American desert vegetation type (or biome) of sparsely but evenly spaced desert plants dominated by creosote bush (Larrea tridentata) and its associates. Its visual characterization is of widely spaced shrubs that are somewhat evenly distributed over flat or relatively flat desert areas that receive between 2 and 8 inches of rain each year. It covers the majority of the flat desert floor and relatively flat alluvial fans in the Mojave Desert, Chihuahuan Desert, and Sonoran Desert. The dominant plants that typify this vegetation type are creosote bush (Larrea tridentata) and its associates, white bur-sage (Ambrosia dumosa), brittlebush (Encelia farinosa, Encelia actoni, Encelia virginensis), cheese-bush (Ambrosia salsola), Mojave yucca (Yucca schidigera), silver cholla cactus (Cylindropuntia echinocarpa), and beavertail cactus (Opuntia basilaris).

This study noted that responses to the loss of foundation species is dependent on a variety of different factors from the ability of a species to recover to the climate conditions of the ecosystem to the patterns in dominance and explored the possible reasons for the outcomes of the study. The results indicated that in areas with just one dominant foundation species, its loss caused a shift in dominance to a mixed dominant community. For example, the creosote bush dominated shrubland saw a shift in dominance to 32% by other shrubs, 26% by perennial grasses, and 22% by perennial forbs following the removal of creosote bush. Another finding was that regardless of the community type and the species removed, the loss of foundation species resulted in an overall increase in black grama supporting the notion that the outcome is greatly affected by recovery ability of species removed or loss.

In rare cases, a plant species may only be effectively pollinated by a single bee species, and some plants are endangered at least in part because their pollinator is also threatened. But, there is a pronounced tendency for oligolectic bees to be associated with common, widespread plants visited by multiple pollinator species. For example, the creosote bush in the arid parts of the United States southwest is associated with some 40 oligoleges.

The Pronghorn and lechuguilla agave are native species of the Chihuahuan Desert. The creosote bush (Larrea tridentata) is the dominant plant species on gravelly and occasional sandy soils in valley areas within the Chihuahuan Desert. The other species it is found with depends on factors such as the soil, altitude, and degree of slope. Viscid acacia (Acacia neovernicosa), and tarbush (Flourensia cernua) dominate northern portions, as does broom dalea (Psorothamnus scoparius) on sandy soils in western portions.

Centris pallida typically feed on flowers that can withstand the hot temperatures of its habitat. These plants include palo verde (Cercidium microphyllum and Cercidium floridium), ironwood (Olnyea tesota), and creosote bush (Larrea divaricata). The palo verde pollen is the most common, and it gives the bee bread a strong orange color. Due to the large expenditure of energy by males during hovering and/or patrolling, they must consume about 3.5 times their body weight in nectar each day.

Mohave ground squirrels emit a high-pitched "peep" as an alarm call, when startled or when young begin to emerge from their natal burrows. The vocalization is sometimes confused with that of the horned lark, and, in areas where the two species are sympatric, with round-tailed ground squirrels. Mohave ground squirrels can occasionally be sighted perched in Lycium cooperii or in Creosote bush (Larrea tridentata) during mid-morning (9-11 a.m.) hours (April–June) basking in the sun.

In 2010, a reportedly living bristlecone pine in California's White Mountains was measured by Tom Harlan to be 5062 years old. Unfortunately, this pine has not been found after Harlan's death in 2013, and its core has not been located at the Laboratory of Tree-Ring Research. Whether Prometheus should have been considered the oldest organism ever known depends on the definition of "oldest" and "organism". Certain sprouting (clonal) organisms, such as creosote bush or aspen, may have older individuals if the entire clonal organism is considered.

Creosote bush—(Larrea tridentata), that replaced the overgrazed perennial grasslands. ;Grasslands and grazing The native grasslands in the Tularosa Basin were able to support large herds in the wet years of the 1880s. When the Americans first started running cattle, in some places, the native perennial bunchgrasses grew 'as high as a horse’s shoulder' - depending on species. One cowhand estimated in 1889 that 85,000 head were mustered within the basin, but said that was “far too heavy a burden for the range” - or beyond its carrying capacity.

The snail lives on rocky mountain slopes, taking shelter in talus and rockslides. During the dry conditions common in its habitat, the snail seals its shell aperture to solid rock to avoid desiccation. The rock should be rich in calcium carbonate, which the snail uses to form its shell. It is associated with local plant species such as saguaro cactus (Carnegiea gigantea), yellow paloverde (Parkinsonia microphylla), brittlebush (Encelia farinosa), foxtail brome (Bromus madritensis), Natal grass (Melinis repens), creosote bush (Larrea tridentata), and Coulter's lupine (Lupinus sparsiflorus).

Ephemeral water sources only persist in winter-spring and should be considered nonexistent, except during rains, or winter, and standing water only lasts the longest in wetter and cooler years. The elevation of the mountains is such that there are no standing forests, only desert communities of vegetation. This section of the western Sonoran Desert, and local Yuma Desert is in the creosote bush scrub community. Desert ironwood, palo verde, catclaw acacia, saguaros, ocotillo, Anderson thornbush, smoketree, and creosote are some locally adapted tree/bush species.

Ecoregions as currently delineated by the Environmental Protection Agency and World Wildlife Fund The Great Basin Desert is defined by its animals and plants, yet the boundaries are unclear. Scientists have different definitions of the Great Basin Desert, which are often defined by negatives. J. Robert Macey defines the "Great Basin scrub desert as lacking creosote bush." The Great Basin Desert includes several arid basins lacking Larrea tridentata (chaparral) such as the "Chalfant, Hammil, Benton, and Queen valleys," as well as all but the southeast portion of the Owens Valley.
|
|
Conversely, the "Panamint, Saline, and Eureka valleys" have creosote bush, unlike the Deep Springs Valley which includes part of the Great Basin scrub desert. The study and definition of ecoregions can also indicate the boundaries of the Great Basin Desert. In 1987, J.M. Omernik defined a desert ecoregion between the Sierra Nevada and Wasatch Range, naming it the "Northern Basin and Range" ecoregion. In 1999, the U.S. EPA renamed the "Northern Basin and Range" to "Central Basin and Range" and the "(Snake River) High Desert" to the "Northern Basin and Range".

Within California, this common insect occurs throughout the warmer and drier regions of the southern part of the state below elevations of 10,000 feet. They prefer chaparral and desert environments with sufficient vegetation (the creosote bush is a favorite) in which they can climb, hide, and hunt. Their range extends from all of southern California north into the Central Valley and then eastward into Arizona, New Mexico, Colorado, and western Texas. In the late 1980s, they began showing up in southern Idaho, and appear to be migrating northward, adapting to the colder winters along the way.

Trigo Mountains Wilderness, a ridgeline wilderness area on the eastern border of the river proper, 30 miles north of Yuma-Winterhaven. A buckhorn cholla cactus is in foreground; creosote bush scrubland on hillsides. Some of the highest absolute air temperatures (of North America) are recorded in the LCRV, rivaling Death Valley; specifically Bullhead City, Lake Havasu City, Laughlin, Needles, Yuma, or the southeastern deserts of California, west of the Colorado River where extreme heat is the main summertime weather feature. Worldwide, only some deserts found in Africa and in the Middle East stand up with an even hotter summer climate on average.

The Lower Colorado River Valley has unique plant communities because it is it is the most arid part of the desert and it has the highest temperatures, in excess of during the summer. The low humidity means that most plants must have mechanisms that deal with severe water loss through evaporation. The soils tend to be typical desert soils, coarse and without well-developed organic horizons, and plants can only obtain soil water during and very soon after the infrequent rains. Dominant plants in the valleys are low shrubs such as Ambrosia dumosa (white bursage) and Larrea tridentata (creosote bush).

After the species was first discovered in Titus Canyon, further plants were found in the adjacent Fall Canyon. It is known only from about ten locations, mostly in these two canyons, all within the Californian section of Death Valley National Park. It grows in limestone crevices on the canyon walls, often on the north face, in areas dominated by creosote bush scrub. Elisens suggested that Holmgrenanthe petrophila might be a "paleoendemic", originally having a much larger range, but now confined to more sheltered and moister microhabitats in desert canyons as a consequence of a warming and drying trend 11,000–8,000 years ago.
|
|
Adaptation to the dry environment is key. For example, creosote bush and mesquite have tap-root systems that can extend down in order to take advantage of a year-round supply of ground water. The diversity of Death Valley's plant communities results partly from the region's location in a transition zone between the Mojave Desert, the Great Basin Desert and the Sonoran Desert. This location, combined with the great relief found within the park, supports vegetation typical of three biotic life zones: the lower Sonoran, the Canadian, and the arctic/alpine in portions of the Panamint Range.

Typical warm desert species such as creosote bush, white bursage, brittlebush, catclaw acacia, ocotillo, mariola, western honey mesquite, four-wing saltbush, big sagebrush, blackbrush and rubber rabbitbrush grow in this community. The mammalian fauna in the woodland scrub community consists of 50 species, mostly rodents and bats. Three of the five Park woodrat species live in the desert scrub community. Except for the western (desert) banded gecko, which seems to be distributed only near water along the Colorado River, all of the reptiles found near the river also appear in the uplands, but in lower densities.

Plants native to the area are typical of the southern New Mexico foothills and include creosote bush, mesquite, saltbush, cottonwood, desert willow, and many species of cactus and yucca. The Tularosa Basin is an endorheic, or closed, basin; that is, no water flows out of it. Because of this and because of the geology of the region, water in the basin is hard: it has very high total dissolved solids concentrations, in excess of 3,000 mg/l. The Brackish Groundwater National Desalination Research Facility, a Bureau of Reclamation laboratory doing research and development on desalination of brackish water, is located in Alamogordo.

The southern portion consists of a north- south mountain range that drops off gradually to numerous valleys, foothills and sloping bajadas on the east and west flanks. Elevations range from in the northwest portion of the area to at McCullough Mountain in the center of the wilderness. Most of the area is composed of metamorphosed Precambrian rock, granite, and schist, although basalt and andesite flows occur in the northern reaches of the southern portion. Creosote bush (Larrea tridentata) scrub occurs below ; Joshua trees, Mojave yucca (Yucca schidigera), and other cacti occur between ; blackbrush occurs between ; pinyon-juniper occurs above .

Associated species include creosote bush, blackbrush, saltbush, yucca, ragweed, ephedra, rabbitbrush, prairie-clover, James' galleta, cheesebush, Anderson's desert thorn, prickly pear, indigo bush, and cliffrose. The plant is nearly an obligate gypsophile, mainly limited to the gypsum soils of the Kaibab Limestone; it has also been seen on limestone soils. The gypsum is sought after and extensively mined in the area by a process that involves removing the top layer of rock, mining the gypsum-rich deeper layers, and filling the pit with the rubble of the top layer. This process is very destructive to the local habitat.

The hummocky, clumpy form of the grass helps it stabilize loose and blowing sand when it grows in desert dune habitat. It acts as a nurse plant to seedlings of other species, such as cholla and barrel cactus, in turn receiving protection from herbivory by growing next to the spiny plants. It is not palatable to elk and waterfowl. Associated plant species include Larrea tridentata (creosote bush), Ambrosia dumosa (white bursage), Coleogyne ramosissima (blackbrush), Yucca brevifolia (joshua trees), Yucca species, Krameria erecta (range ratany), Krascheninnikovia (winterfat), Encelia farinosa (brittle bush), Ephedra species, Lycium andersonii (wolfberry), and Sphaeralcea (globemallow).

Plant communities and wildlife found on the Range vary with altitude and climate. Most of these plant species can be seen while driving the Mormon Well Road (which can be accessed from the Corn Creek Field Station). The desert shrub community, composed of creosote bush and white bursage are the dominant shrubs in the hottest, lowest elevations of Desert National Wildlife Range. Above the valley floor, Mojave yucca and cactus become abundant. At the upper edge of the desert shrub communities, between approximately 4,200 to 6,000 feet (1300 to 1800 m), black-brush and Joshua tree are dominant.

The vegetation of the area mainly consists of desert plants, such as creosote bush, scrub oak, yucca, cacti, and sagebrush. Various types of desert shrubs are found in the park against the rock formations Wildlife in Snow Canyon includes the Gila monster, peregrine falcon, and desert tortoise. Small fences to keep the ground-dwelling creatures from accidentally wandering onto roads can be seen across Snow Canyon and the St. George area. Other notable wildlife include the giant desert hairy scorpion, coyote, Mojave sidewinder, red-spotted toad, Utah banded gecko, and the side-blotched lizard, among many others.

Vegetation on the lower parts of the mountains is xeric shrublands scrub habitat, composed of Creosote bush (Larrea tridentata), California Barrel Cactus (Ferocactus cylindraceus), and Mojave yucca (Yucca schidigera). The habitat dramatically shifts with elevations above 4000 feet to a sky island where numerous animals and plants flourish in the added moisture caught by the mountains. The plant habitat includes forests of Single-leaf Pinyon (Pinus monophylla) and California Juniper (Juniperus californica), and remnant chaparral and woodlands with Oaks (Quercus turbinella) and Manzanita in these higher parts of the mountains. Mitchell Caverns is home to two endemic species of insects found nowhere else.

Characterized by extreme aridity, Inyokern is situated in a wide valley at the base of the eastern escarpment of the Sierra Nevada mountain range. Rugged mountains more than in elevation west of the area create a pronounced rain- shadow effect, resulting in a shrub-steppe habitat zone with annual rainfall of less than . The flora of the valley floor consists primarily of Creosote Bush (Larrea tridentata), Burrobush (Ambrosia dumosa), and several varieties of native bunch grasses. The transition zone of the nearby foothills also contain mixtures of pinyon pine, Joshua tree forests, and concentrated riparian habitat surrounding the small streams descending from the mountain peaks.

Many areas that were historically known to be rich perennial grasslands are now xeric desert shrublands, with creosote bush—(Larrea tridentata) predominating. ;Groundwater salinization Since surface water was unable to sustain the cattle herds, ranchers turned to groundwater, and the easily reachable aquifer of 'sweet water' was pumped out and depleted from under the basin, leaving only brackish water. Applying the groundwater to the surface resulted in additional salts being dissolved and transported back down by groundwater recharge into the aquifer, increasing its salinity. By 2000, it became clear that salts in the aquifer needed to be significantly reduced if existing levels of water use were to continue.

This rapid uptake causes branches to grow several centimeters at the end of a wet season. Water loss is reduced by the resinous waxy coating of the leaves, and by their small size, which prevents them from heating above air temperature (which would increase the vapor pressure deficit between the leaf and the air, thus increasing water loss). Plants drop some leaves heading into summer, but if all leaves are lost, the plant will not recover. Accumulation of fallen leaves, as well as other detritus caught from the passing wind, creates an ecological community specific to the creosote bush canopy, including beetles, millipedes, pocket mice, and kangaroo rats.

Vegetation assemblages of the Gran Desierto are typical of the lower Sonoran Desert with a marked difference in vegetation type and density with location. Large areas of the southern and eastern sand sea, especially near the margins, have a moderately dense (up to 20%) cover of perennial low shrubs and herbs such as bursage (Ambrosia dumosa) and longleaf jointfir (Ephedra trifurca) with creosote bush (Larrea tridentata) in areas of thin sand cover. Palo verde/acacia/ocotillo communities occur on alluvial slopes on the northern side of the sand sea, particularly in arroyos and washes.Felger, R.S., Vegetation and flora of the Gran Desierto, Sonora, Mexico, Desert Plants, 2, 87-114, 1980.

The exiled Ukrainian poet and painter Taras Shevchenko participated in the expedition, and painted a number of sketches of the Aral Sea coast. For the navigation season of 1851, two newly built steamers arrived from Sweden, again by caravan from Orenburg. As the geological surveys had found no coal deposits in the area, the Military Governor-General of Orenburg Vasily Perovsky ordered "as large as possible supply" of saxaul (Haloxylon ammodendron, a desert shrub, akin to the creosote bush) to be collected in Aralsk for use by the new steamers. Unfortunately, saxaul wood did not turn out a very suitable fuel, and in the later years, the Aral Flotilla was provisioned, at substantial cost, by coal from the Donbass.

Elaphe rosaliae is largely confined to mesic and dry desert habitats (rocky - arroyos and washes) in the immediate vicinity of small springs (Ottley and Jacobsen 1983, Stebbins 1985) but individuals have also been observed on hillsides and dry mesas away from water sources (L. Grismer, pers. comm.). The habitat components critical to this snake have not been identified precisely, but it may require some kind of shrub or tree with a moderately dense crown in which to take refuge because it has been taken in native fan palms (Washingtonia spp.), date palms (Phoenix dactylifera), mesquite, palo blanco (Lysiloma candidum), palo verde, and creosote bush associations in the past (Price 1990b). The locations of oviposition sites are unknown.

The National Monument is surrounded by the Tonto National Forest, which includes low plains, desert scrubland, and alpine pine forests. The Upper Sonoran ecosystem is known for its characteristic saguaro cacti. Other common plants include: cholla, prickly pear, hedgehog, and barrel cactus (flowering from April to June); yucca, sotol, and agave; creosote bush and ocotillo; palo verde and mesquite trees; an amazing variety of colorful wild flowers in good years (February to March); and a lush riparian area which supports large Arizona Walnut, Arizona Sycamore, and hackberry trees. It also serves as a home for native animals such as whitetail and mule deer, mountain lion, bobcat, three rattlesnake species and many more.

Other, longer-lived organisms are clonal colonies, such as a quaking aspen (Populus tremuloides) colony named "Pando" in the Fish Lake National Forest in south-central Utah which has been estimated to be 80,000 years old, although precise estimates of clonal organisms such as this aspen colony are impossible with current technologies, and other scientific attempts to age Pando have estimated it may be much younger; the 11,700-year- old creosote bush (Larrea tridentata) colony, named "King Clone", in the Mojave Desert near the Lucerne Valley in California; and the 9,500-year-old Norway spruce (Picea abies) colony named "Old Tjikko" in Sweden. Methuselah, however, is the oldest known non-clonal organism.

In habitat dominated by mesquite and creosote bush in San Diego County, California, all white-throated woodrat houses were located at the bases of honey mesquite. Twenty to 26-foot tall (6–8 m) honey mesquite were preferred over 3 to 10 foot (1–3 m) tall honey mesquite, probably because they provided more shelter and abundant, accessible food. An exception in habitat dominated by mesquite occurred on the Santa Cruz river bottom near Tucson, Arizona, where white- throated woodrat houses were also built under netleaf hackberry, American black elderberry (Sambucus nigra), skunkbush sumac (Rhus trilobata), bear grass (Nolina spp.), or saguaro. In habitats where yucca are abundant white- throated woodrats use the base of yucca for shelter sites.

Cylindropuntia bigelovii grows in desert regions at elevations to about in the "Low Desert" or Colorado Desert of Southern California, and in other Sonoran Desert regions of the Southwestern United States and northwestern Mexico. In the Lower Colorado River Valley, the most dense Cylindropuntia bigelovii stands are at higher elevations, in the rockiest sites. There are fewer Sonoran Desert or Colorado Desert plant association species, but two are common though reduced in size: ocotillo (Fouquieria splendens) and saguaro (Carnegiea gigantea). The teddy bear cholla is also found in a protected Cholla Cactus Garden as part of the Joshua Tree National Park among other desert plants such as the desert senna, pencil cholla, creosote bush, jojoba, and climbing milkweed Sarcostemma cynanxhoides ssp.

It occurs mostly in areas with a water source; in the southwestern US deserts it is commonly in the dry washes, intermixed with other species. In the "creosote bush scrub" Yuma Desert-(western Sonoran Desert) of southwest Arizona, it is found with the palo verde, Bebbia, Encelia farinosa, desert ironwood (Olneya tesota), Lycium andersonii (wolfberry or Anderson thornbush), Psorothamnus spinosus (a type of smoke tree), and Acacia greggii, as some common associated species of the washes, elevation dependent. In Arizona, found from central to southwestern Arizona of the Sonoran Desert; in northwest Arizona found in regions of the Mojave Desert. In southern California and Nevada, desert lavender is found in southern regions of the Mojave Desert and the Colorado Desert of southeast California. File:Hyptisemoryi.

Originally, Tempe Butte was part of a series of horizontal layers, but the strata has been tilted associated with the formation of South Mountain, and millennia of erosion has created the distinctive hogback of resistant andesite, over sedimentary deposits and rhyolite beds. Despite intensive development, the butte and its immediate surroundings continue to support a variety of native vegetation, including saguaro, buckhorn cholla, barrel cactus, creosote bush, wolfberry, mormon tea, sweetbush, desert lavender, California buckwheat catclaw acacia, palo verde and mesquite. Springtime annuals include Coulter's and Arizona lupine (Lupinus sparsiflorus and Lupinus arizonicus), Coulter's globemallow (Sphaeralcea coulteri), popcorn flowers (Cryptantha), fiddlenecks (Amsinckia), heliotropes (Phacelia), blonde plantain (Plantago ovata) and others. During the summer wild buckwheat (Eriogonum deflexum) blooms, leaving behind a "skeleton" in the fall.
