Gopherus agassizii Testudinidae Existing data on social behavior of the desert tortoise Gopherus agassizii suggest that wild populations have dominance hierarchies, possibly related to defense of such resources as burrows, mates, and nests. Tortoises know locations of burrows, mates, water catchments, and mineral licks within their home ranges (1-268 ha). They may take excursions outside customary activity areas and make long-distance movements of 1.4-7.3 km of 16 days to 5 year duration. Relocated tortoises may settle at release sites, travel in straight lines (Type II navigation), and disperse distances of 6.6 km or more. Thus, areas to be restocked should be at least 14 km in diameter to permit dispersal of relocates. Relocated tortoises may disrupt the social structure of resident populations by displacing residents, or they may be driven away by residents.
