An endangered species that live in the desert is the Desert Tortoise. It lives in the Mojave Desert and the Sonoran Desert.
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

Indicator species can be used in one of two ways: * the indicator species is one which easily affected by the pollutant. Specimens are kept in an area and observed. When they show distress the pollution rate is climbing, and this happens before the hardier species are impacted. Think of canaries in coal mines. * When a biologist inspects an ecosystem he keeps track of the population and the species present. If only hardy (pollution resistant) species are present the ecology has become degraded. If sensitive species are present the environemt is still good.
This desert area is an example of a desert ecosystem. It supports a diverse range of flora, such as cacti and brush, and fauna, including birds, snakes, lizards, and rodents, all adapted to the harsh, arid conditions. Such ecosystems are characterized by low precipitation, extreme temperatures, and specialized adaptations among the species that inhabit them.
There is no species called the "desert rattlesnake" but there are dozens of species that live in the desert. The image above is one of them.

The exact number is not known, but there are around 3,500 species of plant species in the Namib desert.
