Abstract

The collared peccary (Pecari tajacu) is distributed from southwestern USA to northern Argentina; however, in some Argentinean localities it went extinct over 50 years ago. As part of a rewilding project, two peccary groups (one captive-bred family group and one mixed group formed by not genetically related individuals) were reintroduced to the Ibera National Park. Following the release, we monitored the movements of 16 individuals to obtain GPS locations every 100 min, for 6 months. We evaluated the individual’s spatial patterns by assessing site fidelity, home range changes, and habitat selection. Most members of the family group survived and established a home range whereas almost all members of the mixed group dispersed and did not survive. Using the Autocorrelated Kernel Density Estimator, the groups’ home range was 8.9 ± 1.7 km2 for the entire study period. In addition, individuals showed high fidelity to release site and a stable home range a few months after release. At larger scales (second order of selection), peccaries selected forested habitat and proximity to release site while at a smaller scale (third order of selection), they avoided grasslands. We highlight the importance of familiarity of individuals prior to release and provide recommendations for future reintroductions. Three years later, by September 2019, nine groups were established in the Ibera National Park and the abundance was over 45 individuals. This is the first post-release assessment of the movement patterns of collared peccaries in South America.
