Abstract: The reindeer (Rangifer tarandus) is an endangered species distributed in the sub‐arctic region in the northeastern part of China .To determine the current status of the population and the distribution pat‐terns of reindeer ,this study was conducted in the Great Xing’Anling of China during July 2012 to August 2013 .The results showed that the reindeer in China only occurs in Genhe area of Inner Mongolia (E 121° 11′-122°25′,N 50°42′-51°50′) ,where has been the dwelling region of Ewenki people .There were 718 reindeer in 12 populations in 2013 with the population range from 9 to 240 and the average population size of 59.83 ( ± 18.42 ,n=12) ,which indicated that the most reindeer populations in China were small popula‐tions .The preferred habitats of reindeer locates from 700 to 926 m with the average of 813.67 m (± 21.72 , n=12) .Small populations and the related inbreeding ,habitat loss and degradation ,management policy ,in‐tensive tourism and poaching and the predation have been the main factors influencing the population increase of reindeer in China .
