Abstract:A survey was conducted to study group size, composition and the degree of social segregation of the introduced Hainan eld’s deer. A total of 362 groups, including a mixed group (165), male group (48), female group (43), and cow-calf group (106), were observed in the Hainan Houmiling Nature Reserve from 2007 to 2008. The group sizes varied greatly and the mean group size was 6.33±3.00. Either frequency or sizes of male-female mixed groups was higher than those of single sex groups. The social segregation indexes varied yearly from 0.02 to 0.21 with a mean of 0.09±0.06. The degree of sexual segregation in the deer was relatively low, and the males and females tended to stay together. The results may be partly explained by an activity-budget hypothesis. Other factors, such as the availability of grassland resources, calving and suckling (female), antler-growing (male) and sampling scale may have had effects on sexual segregation. We also put forward proposals on the conservation of this animal in the article.
