Testudinidae Population Attributes of Desert Tortoises at the National Training Center, Fort Irwin, California: Located in the central Mojave Desert, the National Training Center at Fort Irwin contains habitat for the threatened desert tortoise, an indicator species of desert ecosystem health. While similar causes of death and cumulative disturbances of habitat occur elsewhere in the geographic range of the desert tortoise, military bases such as Ft. Irwin have a unique set of disturbances typical of training areas. A recent USGS study published in the Journal of Arid Environments provides a snapshot of Ft. Irwin tortoise population attributes, status, and relationships between tortoise densities and human activities. USGS scientist Kristin Berry and colleagues sampled 21 study plots at the National Training Center once between 1997 and 2003. Their survey revealed low densities and high death rates of desert tortoises on most plots. Tortoises had died from multiple anthropogenic causes, and many showed moderate to severe signs of disease.
