Abstract: Dafeng David's Deer Reserve takes introduction and protection of david's deers as its main objectives.In the past ten years,the population of david's deer in the Reserve has been increased from 39(introduced from abroad)to the present size of 268 which has greatly contributed to the introduction,preservation and rehabilitation of the david's deer population.However,the habitat in the semi-free range of the reserve is getting worse as a result of the population growth.The problem should be solved by:(1)expansingthe semi-free range;and(2)improving the habitat in the range through effective approaches so as to increase its stock capacity.In this paper,the countermeasures an suggestions on the improvement of habitat in the reserve have been put forward.
