  China is one of 17 megadiverse countries, lying in two of the world's major biogeographic realms: the Palearctic and the Indomalayan. By one measure, China has over 34,687 species of animals and vascular plants, making it the third-most biodiverse country in the world, after Brazil and Colombia. The country is a party to the Convention on Biological Diversity; its National Biodiversity Strategy and Action Plan was received by the convention in 2010.
  
  China is home to at least 551 species of mammals (the third-highest in the world), 1,221 species of birds (eighth), 424 species of reptiles (seventh) and 333 species of amphibians (seventh). Wildlife in China shares habitat with, and bears acute pressure from, one of the world's largest population of humans. At least 840 animal species are threatened, vulnerable or in danger of local extinction, due mainly to human activity such as habitat destruction, pollution and poaching for food, fur and traditional Chinese medicine. Endangered wildlife is protected by law, and as of 2005, the country has over 2,349 nature reserves, covering a total area of 149.95 million hectares, 15 percent of China's total land area. Most wild animals have been eliminated from the core agricultural regions of east and central China, but they have fared better in the mountainous south and west. The Baiji was confirmed extinct on 12 December 2006.
  
  China has over 32,000 species of vascular plants, and is home to a variety of forest types. Cold coniferous forests predominate in the north of the country, supporting animal species such as moose and Asian black bear, along with over 120 bird species. The understory of moist conifer forests may contain thickets of bamboo. In higher montane stands of juniper and yew, the bamboo is replaced by rhododendrons. Subtropical forests, which are predominate in central and southern China, support a high density of plant species including numerous rare endemics. Tropical and seasonal rainforests, though confined to Yunnan and Hainan, contain a quarter of all the animal and plant species found in China. China has over 10,000 recorded species of fungi.
