BEIJING, Aug. 11 (Xinhua) -- China's Ministry of Natural Resources announced Monday that the country has completed property rights registration for its first five national parks, a key step in advancing ecological conservation.

The five national parks, namely the Sanjiangyuan National Park, the Giant Panda National Park, the Northeast China Tiger and Leopard National Park, the Hainan Tropical Rainforest National Park and the Wuyishan National Park, now have their ownership of various natural resource assets formally established and declared through statutory registration.

This registration defines the scope of authority for different levels of government, clarifies ownership, oversight and responsibilities for natural resources, and strengthens property rights management in national parks.

National parks contain the most vital parts of China's natural ecosystems -- marked by unique landscapes, exceptional natural heritage and unparalleled biodiversity.

These five parks, established in 2021 as China's first batch of national parks, span a protected land area of 230,000 square km and are home to nearly 30 percent of the country's key terrestrial wildlife species.
