Antelope rebound impacts grasslands

The rebound in numbers of the once-endangered Tibetan antelope has come with some unintended consequences, a conservation official said on Wednesday.

While the species' survival is more assured now, its growing numbers also have put some pressure on fragile mountain grasslands.

The antelope population had declined to about 70,000 in the early 1990s from poaching, but it has reached about 250,000 nationwide, including 150,000 in the Tibet autonomous region, according to a report by the Chinese Academy of Sciences released on Wednesday.
