Individual identification and population size assessment for Asian elephant based on camera-trapping techniques
摘要
Abstract
We studied and assessed the minimum population number of Asian elephants (Elephas maximus) in Shangyong Sub-Reserve (SYSR),Xishuangbanna National Nature Reserve in Yunnan Province,China using camera-traps.We set up 27 camera-traps in SYSR from January to April 2016,which ran for a total of 621 camera-trap days and obtained 1 944 sample photographs.Within this period individual camera units were active for between 9-52 full days (mean =24).We identified a minimum number of 69 unique individual elephants from photographs (38 adults,16 sub-adults,15 calves) in SYSR.We detected 7 Asian elephants that moved actively across the China-Laos border.The advantages and disadvantages of our camera-trap methodology compared with those of other techniques for individual identification is discussed,and we explore the potential for robust methods for fast,real-time and effective population evaluation in the future.This study strengthened our understanding of Asian elephant status in SYSR and provides scientific evidence to support conservation planning and actions.关键词
