The western box turtle is composed of two subspecies: the ornate box turtle (T. ornata ornata) and the desert box turtle (T. o. luteola). The latter is the westernmost subspecies, ranging from the Pecos River in New Mexico west to the Altar Valley in Pima County, Arizona. While many studies of the ornate box turtle have been published, relatively few studies have been conducted on the life history of the desert box turtle. Data were collected over a period of 12 years on a population in the San Pedro River Valley of Cochise County, Arizona. The study site is located on Fort Huachuca at the ecotone of semi-arid grasslands and Madrean evergreen woodland communities. The site has no permanent water, but is transected by an ephemeral stream and associated xeroriparian community. Observations were made through a combination of radio telemetry (1997-2001) and broad area searches. Seasonal activity patterns were tied to summer monsoon rains, with individuals generally exhibiting crepuscular daily activity patterns. Mean home range size is estimated at 4.76 hectares (ha) using 95% minimum convex polygons, with no differences between males and females observed. Adult population size is estimated at 99 individuals, with a density of approximately 0.5 adults per hectare.
