  1. Protect habitat: All reptiles (excluding sea turtles)

    A replicated, site comparison study in 2011–2012 in five sites of dry forest, brush and grassland or agricultural lands in La Pampa, Catamarca and Santiago del Estero, Argentina (Sanchez  et al. 2014) found that Argentine tortoises Chelonoidis chilensis were present in one of two protected areas and two of three unprotected sites surveyed. Fourteen tortoises were present in one protected area and none in the second protected area. Three tortoises were counted in two unprotected sites surveyed (1 or 2 tortoises/site) and none in a third unprotected site. In November 2011–March 2012, Argentine tortoises were surveyed in two protected areas and three unprotected sites. Visual encounter surveys were carried out on foot using line transects (100 m long, 30 m wide) and covered 171,000 m2 in each area or site (8–15 hours survey time/site).
