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. Deserts are arid regions that are generally associated with warm temperatures; however ...
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 ...
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation .
The Mojave Desert is the hottest desert in North America, located primarily in southeastern California and Southern Nevada. Its total area is 22,000 sq mi (57,000 km 2). The largest cold desert is the Great Basin Desert, which encompasses much of the northern Basin and Range Province, north of the Mojave Desert.

Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.

The stark ratio of oasis to desert land in the world means that the oasis ecosystem is "relatively minute, rare and precious." [9] There are 90 “major oases” within the Sahara Desert. [5] Some of their fertility may derive from irrigation systems called foggaras, khettaras, lkhttarts, or a variety of other regional names. [11] [12]
Human disturbance poses the number one concern to this fragile ecosystem. The Sonoran desert contains the two large cities of Tucson and Phoenix, Arizona, which contain over 3 million people. [15] These dense human populations deplete the water table of the entire desert and are sending the desert towards desertification.
