Reintroductions have been increasingly used in wildlife conservation. Understanding movement patterns in the early post-release period is critical for the survival and reestablishment of reintroduced animals. However, there was little information available on early post-release movement of reintroduced Eld’s deer (Cervus eldi hainanus). Using GPS collars for five reintroduced Eld’s deer in the Datian National Nature Reserve, early post-release movement of reintroduced Eld’s deer (2 captive-breeding animals, 3 wild animals) have been studied. We defined early post-release period as the first dry season (March – June) after release to control for potential seasonal effects on deer movements. Movements were compared between each 30-day period. Four time periods were included for captive-breeding deer and three time periods for wild deer as they were released in end of March. Movement and dispersal distance were processed by R package “adehabitatLT” in R3.5.1. Movement rates were compared between 30-day periods using one-way analysis of variance (ANOVA) with post hoc Tukey’s HSD test. Dispersal distance between 30-day periods and movement rates at different times of day were done using one-way analysis of variance (ANOVA) with hoc Bonferroni-Dunn test. The kernelUD method was used to construct 50% core and 95% full home range cumulative utilization distributions using R package “adehabitatHR in R3.5.1. Research results showed that released captive-breeding deer significantly increased movement rates and dispersal distance in fourth time periods (Fig. 1 and 3), and their 50% core and 95% full home range cumulative utilization distributions continued to grow after release (Fig. 4). All the information indicated that captive-breeding deer would continue to disperse and explore after release. Movement rates of released wild deer had no obvious changes (Fig. 1). However, their dispersal distance, 50% core and 95% full home range cumulative utilization distributions significantly reduced in third time periods (Fig. 3 and 4). That indicated that released wild deer returned to the area surrounding the release site after initial exploration. Released captive-breeding deer in general moved more during daytime from release to third time periods, but showed a distinct crepuscular bimodal activity patterns in fourth time periods (Fig. 2). Released wild deer had always been crepuscular bimodal activity patterns after release (Fig. 2). Results indicated that adaptability to new environment of released wild deer would be stronger than released captive-breeding animals.
