Field Survey of Alien Plants in Habitats of Hainan Eld's Deer ( Cervus eldi hainanus )
Hainan Eld's deer ( Cervus eldi hainanus ) is a national - level protected species and endemic to China. The stability and development of Eld's deer habitats play a significant role in population growth. Alien invasive plants can affect habitats ir- reversibly over long time periods. We surveyed the alien plants in Hainan Datian National Nature Reserve, where Hainan Eld's deer occur, using line transects and quadrats from 2009 to 2011. We recorded 115 alien plant species of 40 families and 95 genera. Among these, 80 herbs accounted for 70% and most are tropical species, 50% were introduced from the Americas and were mainly distributed in grasslands. The widely distributed alien plants impact the abundance and distribution of native spe- cies and may have a negative effect on Eld's deer food resource in future. We make several recommendations for effective man- agement and conservation. Our survey results can provide a basis for maintaining the stability of Hainan Eld's deer habitat.
