Abstract

Historically, the collared peccary (Tayassu tajacu) occurred throughout much of Texas including the northern portion of the Texas Hill Country. Remaining peccary populations were extirpated in much of their former range due to over harvest and habitat loss. In 2004, efforts to restore peccary populations to the Texas Hill Country began when Texas Parks and Wildlife Department biologists translocated 29 collared peccaries into the 2,157 ha, Mason Mountain Wildlife Management Area (MMWMA). I evaluated the success of peccary translocations for mixed and intact family groups by comparing survival, ranges, and dispersal of translocated, radio-tagged peccaries. In addition, I evaluated two release methods (soft versus hard) to determine differences in population demographics. I found that peccary ranges and dispersal patterns did not differ (P > 0.05) between intact and mixed groups or release method (soft versus hard). However, I did find that peccary fidelity to release sites was greater for soft releases of family groups. Individuals from the soft release group dispersed the shortest distance and stayed on MMWMA. Only 2 individuals from the hard releases stayed on MMWMA while the rest (19 individuals) dispersed 4-8 km. Future peccary translocations should emphasize the release method employed and family structure of individuals released to improve translocation effectiveness in establishing populations in target areas.
