The International Union for Conservation of Nature (ICUN) reclassified the giant panda last year from endangered to vulnerable, after their numbers rose by 17% between 2003 and 2013.

An estimated 1,864 pandas live in the wild, where the main threat is habitat loss; China wants to increase the number to 2,000 by 2025.

As well as the giant panda, the national park will help protect 8,000 endangered animals and plants, Xinhua said.

It will also ensure one authority is responsible for protecting pandas across the Gansu, Shaanxi and Sichuan provinces in south-central China, which the park straddles. At the moment the animals fall under different jurisdictions when they cross boundaries.

“It will be a haven for biodiversity and provide protection for the whole ecological system,” Hou Rong, the director of the Chengdu Research Base for Giant Panda Breeding in Sichuan province, told Xinhua. “Many scientists and conservation experts support the building of a national park.”

The proposed reserve will span three Chinese provinces where an estimated 1,864…
