     Though its number is increasing ,the Hainan deer is not yet out of the woods of endangerment. That is , it is

in great danger.

     The Hainan deer, or EId's deer, is found only in Hainan Province of South China. It looks similar to the sika

deer, but bears no plum flower spots on the body.

     In the Datian Nature Reserve of Hainan the deer population has increased from 26 in 1976 to the present

500. But with the development of the island in recent years, the Hainan deer is faced with more serious

challenges to go on living.

     The Datian Reserve is only 13 square kilometers in area, which is too small for the Hainan deer to find good

places or enough food.

      Because more and more people have moved to the island and settled here, more land is used for building.

Weak deer which are driven out by their fellows are threatened by human neighbours. Illegal hunting is pushing

the valuable deer into difficult situation.

     The Hainan deer is brown, with the female lighter in colour, and has a clear black line across the back. They

like to feed in bamboo forests, bushes and grassland under the rocks. They belong to herbivores, which feed on grass instead of meat.

      From mid-January to June is the breeding season for the Hainan deer. The male deer fight against one

another with their antlers to determine the order to breed. The top winner has many more choices than the

others.

     In September, the female deer start to bear fawns. The little deer follow their mothers until two years of age.
