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 ...
Sand dunes in the Sahara Desert. Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat.
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
Sagebrush scrub occurs in relatively deep soils along the Sierra-Cascade axis, running from Modoc County to San Bernardino County. [4]In the Sierra Nevada range, in California, sagebrush associates include bitterbrush (Purshia tridentata), curl-leaf mountain-mahogany (Cercocarpus ledifolius), and rabbitbrushes (Chrysothamnus spp., Ericameria spp.).

California has two high deserts: the Mojave Desert and the Great Basin Desert. The Mojave Desert ecoregion is marked by the presence of Joshua trees. [3] The dry cold Great Basin desert of California consists of the Owens Valley, and is classified into Great Basin shrub steppe by the WWF, [4] and into the Central Basin and Range ecoregion by ...
A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season. Caatinga falls entirely within earth's tropical zone and is one of 6 major biomes of Brazil. It covers 912,529 km², [2] nearly 10% of Brazil's territory.
Mediterranean forests, woodlands and scrub is a biome defined by the World Wide Fund for Nature. [1] The biome is generally characterized by dry summers and rainy winters, although in some areas rainfall may be uniform. Summers are typically hot in low-lying inland locations but can be cool near colder seas.
