The Hoh-Xil National Nature Reserve in the Tibet Autonomous Region is preparing for another birthing season of the endangered Tibetan antelope. The species has long been threatened by the international demand for their luxurious wool. Anti-poaching initiatives by local agencies are struggling to cover this enormous habitat. Fintan Monaghan takes a look at what is being done to help these endangered creatures.

Zonag Lake, a "big maternity ward" for Tibetan antelopes.

Each year in the middle of June, great herds of the endangered animals can be spotted roaming on the banks of the lake.

Snow storms have become a frequent visitor in recent times.

These antelopes have migrated huge distances to reach the place where they give birth.

Tseta, director of Hoh-Xil National Nature Reserve Admi., said, "There are five herds of pregnant antelopes. None have given birth yet."

The staff aren't the only ones watching the herds.

Luckily, the antelopes are great runners.
