China holds 34,687 known species of animals and 37,018 known species of plants as documented in the national biodiversity census conducted by the Ministry of Ecology and Environment between 2013 and 2021. The territory spans five major climate zones from subarctic forests in Heilongjiang province through temperate woodlands and tropical rainforests in Yunnan to alpine tundra on the Tibetan Plateau. This produces habitat range sufficient to support the giant panda, the snow leopard, the Yangtze finless porpoise, the Chinese alligator, the South China tiger, the crested ibis, and the Tibetan antelope within the same national borders. The Wildlife Protection Law enacted in 1988 and amended in 2016 divides protected species into two tiers with criminal penalties for unauthorized hunting, trade, or habitat disturbance. Category I species receive the highest protection level and include 98 mammals, 55 birds, 39 reptiles, 8 amphibians, 8 fish, and 24 invertebrates according to the 2021 revision administered by the National Forestry and Grassland Administration.
The giant panda population reached 1,864 individuals in the wild as of the 2014 national survey published by the State Forestry Administration, representing an increase from 1,596 individuals counted in the 2003 survey. Wild populations occupy six mountain ranges in Sichuan, Shaanxi, and Gansu provinces totaling 2,577,000 hectares of bamboo forest between 1,200 and 3,400 meters elevation. The Sichuan Giant Panda Sanctuaries inscribed as a UNESCO World Heritage site in 2006 protect 924,500 hectares across seven nature reserves and nine scenic parks containing more than 30 percent of the world's wild giant pandas. Wolong National Nature Reserve established in 1963 covers 200,000 hectares in Wenchuan County and hosts the China Conservation and Research Center for the Giant Panda which maintains 67 captive breeding enclosures. Foping National Nature Reserve in Shaanxi province recorded the highest wild panda density at one individual per 2.5 square kilometers during the 2014 survey. The species consumes between 12 and 38 kilograms of bamboo daily depending on the part of the plant eaten, with arrow bamboo and umbrella bamboo forming the primary diet in different elevation zones.
The snow leopard range within China covers approximately 1,100,000 square kilometers across the Tibetan Plateau, Tian Shan, Kunlun, and Himalayan ranges according to the Snow Leopard Network assessment published in 2016. Population estimates for China remain uncertain with reported figures between 2,000 and 2,500 individuals representing roughly 40 percent of the global population. Sanjiangyuan National Park established in 2016 protects 123,100 square kilometers of headwater habitat for the Yangtze, Yellow, and Mekong rivers at elevations between 3,500 and 6,564 meters where snow leopards prey on blue sheep, Tibetan gazelle, marmots, and pika. Qilian Mountain National Park created in 2017 encompasses 50,200 square kilometers along the Gansu and Qinghai border containing documented snow leopard corridors between isolated mountain blocks. Camera trap surveys in Wolong Nature Reserve between 2011 and 2013 recorded snow leopards at elevations as low as 2,500 meters hunting tufted deer and takin during winter months when high-elevation prey migrates to lower slopes.
The South China tiger exists only in captivity following the last confirmed wild sighting in 1970 in Yihuang County, Jiangxi province. The captive population numbered 207 individuals across 19 Chinese institutions as of 2021 according to the Chinese Association of Zoological Gardens studbook coordinated by the Shanghai Zoo. All living South China tigers descend from six wild-caught founders captured between 1958 and 1970, producing an inbreeding coefficient of 0.23 indicating substantial genetic bottleneck effects documented in veterinary health records showing reduced fertility and increased juvenile mortality rates.
The Yangtze finless porpoise population declined from approximately 1,800 individuals in 2006 to 1,012 individuals in the 2017 survey conducted by the Institute of Hydrobiology at the Chinese Academy of Sciences using visual transect counts along 3,400 river kilometers. The species represents the only freshwater porpoise after the functional extinction of the baiji dolphin confirmed in 2006 following a six-week expedition that covered the entire Yangtze main stem without a single sighting. Finless porpoises now concentrate in Poyang Lake which held 457 individuals in 2017, Dongting Lake with 110 individuals, and the main Yangtze channel between Yichang and Shanghai. The population declines correlate with vessel traffic that exceeded 300,000 commercial ship transits annually through the middle Yangtze reaches between 2010 and 2020 according to Yangtze River Administration navigation data. Propeller strikes, underwater noise interference with echolocation, and illegal electrofishing that depletes prey stocks of bighead carp and silver carp represent documented mortality factors. The Tian'ezhou Oxbow Nature Reserve in Hubei province maintains a semi-natural reserve population of 101 porpoises as of 2021 within a 21-kilometer former river meander isolated from the main Yangtze channel by a levee constructed in 1972.
The Chinese alligator survives in wild populations totaling fewer than 150 mature individuals restricted to fragmented wetlands in southern Anhui province according to the 2016 census by the Anhui Research Center of Chinese Alligator Reproduction. The species once ranged along the lower Yangtze River basin across wetlands in Anhui, Jiangsu, Zhejiang, and Jiangxi provinces but agricultural conversion eliminated 90 percent of suitable habitat between 1950 and 1980. Wild alligators now occupy 13 isolated wetland patches totaling 348 hectares in Xuancheng and Wuhu counties where they hibernate in burrows from November through March and feed on snails, mussels, fish, and waterfowl during active months. The Anhui Research Center maintains a captive breeding population of approximately 15,000 individuals descended from 212 wild-caught founders collected between 1979 and 2006, with reintroduction trials releasing 283 captive-bred juveniles into Hongxing and Zhongqiao nature reserves between 2003 and 2020 showing mixed survival results documented in radio telemetry studies.
The crested ibis population recovered from seven individuals discovered in 1981 in Yangxian County, Shaanxi province, to approximately 5,000 individuals worldwide with 2,600 in the wild and 2,400 in captivity as of 2020 according to the Shaanxi Hanzhong Crested Ibis National Nature Reserve annual report. The species was presumed extinct in China following the last confirmed sighting in 1964 until ornithologist Liu Yinzeng located the Yangxian population breeding in oak and pine forests between 800 and 1,200 meters elevation in the Qinling Mountains. Protection measures included eliminating pesticide use within five kilometers of nesting sites, installing electric service to replace wood gathering that disturbed nest trees, and posting guards at active nests during breeding season. The wild population expanded across 16 counties in Shaanxi, Henan, and Gansu provinces with breeding confirmed in Tongchuan City in 2020 marking the easternmost natural range extension. Captive breeding programs at Shaanxi facility produced 1,846 juveniles between 1991 and 2020 with releases establishing populations in Ningshan County in 2007 and Lantian County in 2013.
The Tibetan antelope or chiru population inhabits alpine steppe and meadow habitats between 3,700 and 5,500 meters elevation across the Tibetan Plateau covering portions of Tibet, Qinghai, and Xinjiang provinces. Population estimates increased from approximately 65,000 individuals in 1995 to between 100,000 and 150,000 individuals in 2015 according to surveys coordinated by the World Wildlife Fund and the Forestry Department of Tibet Autonomous Region. Poaching for shahtoosh wool killed an estimated 20,000 antelope annually during the 1980s and 1990s when a single shawl requiring pelts from three to five animals sold for up to $17,000 in overseas markets. The Chinese government deployed armed anti-poaching patrols across Hoh Xil National Nature Reserve starting in 1997, resulting in a decline in documented poaching incidents from approximately 20,000 animals killed in 1990 to fewer than 200 killed in 2015 based on recovered carcasses and confiscated pelts. Female antelope migrate up to 300 kilometers from winter ranges in Qinghai to calving grounds near Zhuonai Lake and Taiyang Lake each June, with radio collar studies tracking migration routes used to establish protection corridors across the Qinghai-Tibet Highway and railway completed in 2006.
The Yangtze sturgeon population collapsed from an estimated 2,000 individuals in 1980 to functionally extinct status in the wild by 2020 following construction of Gezhouba Dam in 1981 and Three Gorges Dam in 2003 which blocked access to upstream spawning grounds in the upper Yangtze reaches above Yichang. The species historically migrated from marine and estuarine habitats near Shanghai upstream 3,000 kilometers to spawning sites in Sichuan province between October and November, with juveniles remaining in freshwater for 5 to 10 years before descending to coastal waters. Monitoring stations operated by the Yangtze River Fisheries Research Institute recorded the last confirmed natural reproduction event in 2013 when 13 eggs were collected downstream of Gezhouba Dam, with no wild spawning detected in surveys between 2014 and 2021. Captive breeding facilities at the China Three Gorges Corporation Rare Fish Station in Yichang maintain approximately 1,000 individuals descended from wild-caught adults collected between 1980 and 2005, with annual releases of 50,000 to 100,000 juveniles into the Yangtze below Yichang since 2009 showing minimal survival based on acoustic tagging studies.
The Chinese giant salamander represents the world's largest amphibian reaching lengths up to 1.8 meters and weights exceeding 50 kilograms in historical records, though contemporary wild individuals rarely exceed 1.2 meters according to surveys by Kunming Institute of Zoology. Wild populations survive in fragmented mountain stream habitats across 12 provinces including Shaanxi, Sichuan, Hubei, Hunan, Anhui, Jiangsu, Zhejiang, Jiangxi, Guangdong, Guangxi, Guizhou, and Chongqing at elevations between 200 and 1,500 meters. Genetic studies published in 2018 identified at least five distinct species-level lineages across the range representing cryptic diversity masked under a single species designation. Commercial farming operations raise an estimated 2.6 million giant salamanders annually in Shaanxi, Hunan, and Guangdong provinces for restaurant trade selling at prices between 800 and 2,000 yuan per kilogram, with documented cases of farm escapes and releases introducing non-native genetic lineages into wild populations and potentially transmitting ranavirus pathogens documented in disease surveys from 2012 through 2019.
The red-crowned crane population in China numbers approximately 1,400 individuals divided between breeding populations in Heilongjiang and Jilin provinces and wintering populations in coastal wetlands of Jiangsu province according to the 2019 census coordinated by the International Crane Foundation. Zhalong National Nature Reserve in Heilongjiang protects 210,000 hectares of freshwater marsh and reed beds supporting approximately 300 breeding pairs that nest from April through July on floating vegetation platforms in water 20 to 60 centimeters deep. Winter populations concentrate at Yancheng National Nature Reserve in Jiangsu province which hosts approximately 800 individuals from November through March feeding on waste grain in harvested rice fields and mudflats in the Yellow Sea coastal zone. Habitat loss from agricultural reclamation eliminated an estimated 70 percent of wetland breeding habitat in the Sanjiang Plain of Heilongjiang between 1950 and 2000, with remaining marsh fragments increasingly isolated by drainage channels and roads that increase predation risk and reduce genetic connectivity documented in microsatellite DNA studies.
The Przewalski's gazelle exists only in fragmented populations around Qinghai Lake in Qinghai province with a total count of approximately 2,800 individuals as of 2020 according to monitoring by Northwest Plateau Institute of Biology. The species once ranged across the northeastern Tibetan Plateau in Qinghai, Gansu, Ningxia, and Inner Mongolia but declined to fewer than 300 individuals by 1990 following habitat conversion to agriculture and competition with domestic livestock. Current populations occupy steppe and meadow habitats between 3,200 and 3,600 meters elevation divided into five subpopulations separated by fences, roads, and agricultural land that prevent genetic exchange. The largest subpopulation of approximately 1,500 individuals occupies the Hudong-Ketu area on the northeastern shore of Qinghai Lake within Bird Island Nature Reserve boundaries, while smaller groups persist at Wayu, Haergai, Shadao, and Jiangxigou locations. Conservation measures include fence modifications with wildlife passages, seasonal grazing restrictions within core gazelle habitat, and compensation payments to herders for livestock reductions averaging 8,000 yuan per household annually since 2012.
The Chinese bahaba or giant yellow croaker once supported major commercial fisheries in the East China Sea and South China Sea but declined to critically low population levels following decades of overfishing using explosives and bottom trawls. The species reaches lengths of two meters and weights exceeding 100 kilograms with individuals producing a swim bladder valued in traditional medicine markets at prices between 70,000 and 400,000 yuan per kilogram depending on size and quality. Wild-caught bahaba became so rare by 2000 that single specimens sold for prices exceeding one million yuan, driving continued illegal fishing despite a total harvest ban implemented in 1990. No population surveys exist, and encounters with living specimens occur primarily as incidental bycatch in trawl nets with fewer than 10 individuals documented annually in fisheries monitoring data from 2010 through 2020. Captive breeding attempts by research institutes in Guangdong and Fujian provinces have produced limited success with high juvenile mortality rates and slow growth requiring seven to eight years to reach sexual maturity.
China established its first national park pilot program in 2015 with 10 designated areas covering 220,000 square kilometers across 12 provinces including Sanjiangyuan, Giant Panda, Northeast China Tiger and Leopard, Hainan Tropical Rainforest, Wuyishan, Shennongjia, Pudacuo, Qianjiangyuan, Nanshan, and Qilian Mountains national parks. The system aims to consolidate fragmented management jurisdictions previously divided among forestry, agriculture, environmental, water, and land management agencies into unified park administrations directly under central government oversight. Sanjiangyuan National Park protects the headwaters of the Yangtze, Yellow, and Mekong rivers across 123,100 square kilometers with resident populations of approximately 60,000 herders incorporated into park management through ranger positions and resource use agreements. Northeast China Tiger and Leopard National Park established in 2017 covers 14,600 square kilometers along the border with Russia and North Korea protecting habitat corridors for approximately 27 wild Siberian tigers and 42 Amur leopards documented in camera trap surveys between 2017 and 2020.
The national nature reserve system encompasses 2,750 reserves covering 1,470,000 square kilometers or 14.9 percent of terrestrial territory as of 2020 according to the Ministry of Ecology and Environment annual report. Categories include national nature reserves numbering 474 sites administered by central government agencies, provincial reserves numbering 902 sites, and municipal and county-level reserves numbering 1,374 sites. Changbai Mountain National Nature Reserve on the border with North Korea protects 196,465 hectares of temperate broadleaf and coniferous forest supporting populations of sable, lynx, Asian black bear, wild boar, sika deer, and approximately 300 bird species. Xishuangbanna National Nature Reserve in southern Yunnan province encompasses 241,776 hectares of tropical seasonal rainforest representing the northernmost extent of Southeast Asian tropical fauna including Asian elephant, clouded leopard, green peafowl, and great hornbill with documented populations of 250 elephants moving across the border with Laos and Myanmar.
