Movement of translocated turtles according to translocation method and habitat structure

Dispersal away from the release site is among the main obstacles that reduce translocation success. Scientists should therefore test a variety of translocation methods to reduce dispersal when moving wildlife between sites. The objective of this research was to examine how translocation method (hard‐ vs. soft‐release) and habitat structure (continuous vs. patchy) affect movement of translocated turtles. A hard‐release consists of releasing individuals to their new environment without any prior acclimation, whereas a soft‐release forces animals to spend time at the release site prior to release. Our results suggest that the most effective translocation technique depends upon habitat structure. A soft‐release was effective in minimizing post‐release dispersal of translocated turtles in a continuous lotic habitat as there was no difference in the movement of soft‐released and resident turtles. However, hard‐released turtles undergo extensive movement when translocated to a continuous lotic habitat as hard‐released turtles had greater movement than resident turtles. When the release site consists of a patchy wetland complex, a hard‐release translocation may be effective as there was no difference in the movement between resident and hard‐released turtles. Our study suggests that both the habitat structure of the release site and translocation method play a role in the movement patterns of translocated wildlife. Semi‐aquatic turtles or species with poor vagility may make better candidates for hard‐release translocations in patchy habitats because these species may be less likely or unable to disperse long distances as result of their behavior, physiology, or the structure of the release site.
