China Nature: Wildlife, Landscapes, and National Parks

China shelters roughly one-tenth of the world’s known plant species and some of its most iconic animals, from giant pandas in bamboo forests to snow leopards on high-altitude plateaus. The country formally launched its first batch of national parks only in 2021, but the ambition behind that system reflects decades of shifting conservation strategy across landscapes that range from tropical rainforest in the far south to frozen tundra along the Russian border. What makes China’s natural heritage unusual is not just the sheer volume of species but the extremes of geography that sustain them, and the speed at which both threats and protections have intensified in recent years.

A National Park System Built From Scratch

For most of its modern history, China relied on a patchwork of nature reserves, scenic areas, and forest parks managed by different government agencies, often with overlapping jurisdictions and inconsistent enforcement. The decision to create a unified national park system represented a fundamental shift, aiming to consolidate the most ecologically valuable territories under a single framework with stronger protections.¹ The first five official national parks, designated in October 2021, span wildly different biomes: the Tibetan Plateau grasslands of Sanjiangyuan, tropical rainforest in Hainan, the temperate forests sheltering Amur tigers and leopards in the northeast, the mountainous panda habitat of western Sichuan, and the subtropical forests of Wuyishan in the southeast.

The rollout has not been without growing pains. In Sanjiangyuan, for example, researchers found that the park’s current boundaries provide insufficient coverage of high-value ecological areas, and that some of the most important zones for ecosystem services sit right at the park’s southeastern edge rather than safely inside its core.² Drawing the right boundaries matters enormously, because the line between “core conservation area” and “traditional use area” determines what human activity is permitted, from grazing to road-building. These boundary decisions are still being refined as park managers accumulate more data on where species concentrate and where ecosystem functions are strongest.

Giant Pandas and the Corridor Problem

The giant panda is the species most associated with Chinese conservation, and its story offers both a success and a cautionary tale. Decades of habitat protection helped pull the species back from the brink, but the forests pandas depend on remain heavily fragmented, especially in the mountains northeast of Chengdu. Habitat-suitability modeling shows that the central portions of Giant Panda National Park score high for panda habitat, while the periphery is broken into disconnected patches with low connectivity between them.³ Researchers have identified dozens of potential ecological corridors to link these isolated patches, totaling over 1,600 km in length across the park’s central area.⁴

Corridors are not just about clearing a path through trees, though. Pandas are bamboo specialists, and a corridor without the right food is a corridor they will not use. Studies have begun mapping which bamboo species grow well in the proposed corridor zones and identified at least four species suitable for replanting along the routes.³ The corridor work also benefits other species that share panda habitat, including golden snub-nosed monkeys and takin, making the investment in connectivity far broader than a single-species effort.

The World’s Rarest Primate on Hainan Island

While pandas attract most of the international attention, one of the planet’s most dramatic conservation stories is unfolding in a tropical rainforest on Hainan Island. The Hainan gibbon is the world’s most critically endangered primate, reduced at one point to fewer than 30 individuals in a single patch of forest. A combination of reforestation of lowland habitat, community engagement, and scientific monitoring has slowly pushed numbers upward, with the population reaching at least five family groups totaling around 34 animals.⁵

One of the more inventive interventions involved stringing mountaineering-grade rope bridges across a natural landslide gap that had cut off part of the gibbons’ range. The first bridge, installed in 2015 and spanning about 16 meters, took the gibbons 176 days to try, but once they started crossing, usage increased steadily. Every member of the group eventually used the bridge except the adult male.⁶ The researchers stressed that rope bridges are a stopgap; restoring continuous forest canopy remains the real goal. But for a species balanced on the edge of extinction, even a short-term fix that reconnects habitat can make the difference between a population expanding its range and one trapped in a shrinking fragment.

Big Cats on the Border

In the northeast corner of China, dense temperate forests along the Russian and North Korean borders harbor the last viable populations of Amur tigers and Amur leopards in Chinese territory. The Northeast China Tiger and Leopard National Park was created specifically to protect and expand habitat for these animals, whose ranges naturally cross international boundaries. That cross-border dimension creates both opportunities and complications. Transboundary landscapes often overlap with biodiversity hotspots and provide habitat for threatened species, but infrastructure like roads, fences, and development along borders fragments the very connectivity those species need.⁷ For Amur tigers, which range over hundreds of square kilometers, cooperation between China and Russia on habitat management is not optional; it is the only way to maintain a population large enough to be genetically viable over the long term.

Snow Leopards on the Roof of the World

The Tibetan Plateau and its surrounding mountain ranges constitute the global stronghold for the snow leopard, and China holds a majority of remaining habitat. Camera-trap surveys in central China have identified populations at densities between roughly 1.5 and 3.3 individuals per 100 square kilometers, though researchers caution that short surveys in limited areas give only a partial snapshot of what is an inherently transient, wide-ranging animal.⁸ In the western Himalayas, where similar camera-trapping methods have been used, snow leopard density is considerably higher in formally protected areas than in adjacent unprotected zones, even when both areas have some human activity, suggesting that protection status itself carries a measurable benefit.⁹

Snow leopards prefer steep, rocky, high-elevation terrain, and that rugged topography both protects them from human encroachment and creates barriers to their own movement. Connectivity analyses have found that major mountain peaks and extremely precipitous ridgelines can block leopard movement between otherwise suitable habitat patches, making the placement of protected-area networks especially important in these landscapes.

Tibetan Antelope and the Railway

The Tibetan antelope, or chiru, undertakes one of the highest-altitude mass migrations on Earth, crossing vast stretches of the Qinghai-Tibet Plateau to reach calving grounds. The construction of the Qinghai-Tibet Railway introduced a physical barrier across these migration routes. When herds reached the railway, they visibly hesitated, gathering into large groups beneath the rail bed rather than crossing freely.¹⁰ Wildlife underpasses were built to allow passage, but their placement does not always align with the animals’ preferred routes. GPS tracking data showed that antelope deviate substantially from their optimal migration paths to reach the available underpasses, adding on average about 86 km to their migration distance.¹¹

That extra distance matters for pregnant females heading to calving grounds, and it illustrates a broader tension in Chinese conservation: major infrastructure projects often include mitigation measures like underpasses, but those measures are designed around engineering constraints rather than animal behavior, and the gap between the two can undermine the intended benefit.

Elephants Moving North

In 2021, a herd of Asian elephants wandered hundreds of kilometers northward from their usual range in Yunnan Province, making international headlines and charming millions of viewers who followed their journey on social media. That trek was unusual in its distance, but the underlying trend is not. Asian elephants in Yunnan have been steadily expanding their range, and research links this expansion to a combination of climate change and decades of enforced habitat protection in human-dominated landscapes.¹² As forests regenerate and warming temperatures shift suitable habitat northward, elephants are following.

The expansion brings them into increasing contact with farms and villages. Studies in Xishuangbanna, the core of China’s elephant range, found that during the dry season, elephant crop raids are highest near secondary roads, forest edges, and low-elevation cropland. In the rainy season, proximity to settlements and higher crop coverage become the dominant risk factors. Across both seasons, the availability of food in agricultural landscapes is the primary driver of conflict.¹³ Managing this conflict is one of the most urgent practical challenges facing Chinese wildlife managers, and there are no easy answers when a protected species weighing several tons decides it prefers your banana plantation to the forest.

The Yangtze Fishing Ban

China imposed a ten-year fishing ban across the entire Yangtze River and its major tributaries starting in 2021, affecting hundreds of thousands of fishers. The stakes were enormous: the Yangtze had experienced seven decades of continuous biodiversity decline, with many endemic fish species nearing extinction and the baiji, or Yangtze river dolphin, already functionally gone. Early results from the ban are encouraging. Researchers documented improvements in fish biomass, body condition, species diversity, and initial recovery of threatened species, effectively halting the long decline.¹⁴

The Yangtze finless porpoise, one of the river’s remaining charismatic species, has responded as well. Monitoring near Wuhan detected increased porpoise presence during the fishing closures, with both the ban and reduced boat traffic during the COVID-19 lockdowns contributing to the heightened sightings.¹⁵ The fishing ban remains politically contentious because it disrupted the livelihoods of entire communities, but the biological response has been swift enough to build a case that the river’s ecosystem can bounce back if given breathing room.

Yellow Sea Mudflats and the Migratory Flyway

China’s eastern coastline sits along one of the world’s most important avian highways: the East Asian-Australasian Flyway, used by millions of shorebirds migrating between breeding grounds in Siberia and wintering areas as far south as Australia. The Yellow Sea’s tidal mudflats are the critical refueling stop in the middle. But these mudflats have been vanishing. At Lianyungang, on the Chinese Yellow Sea coast, roughly a quarter of intertidal soft-sediment habitats were destroyed by land reclamation between 2003 and 2018. Despite that loss, the site still supports 43 shorebird species, including 12 that are globally threatened or near-threatened, and ranks highest among more than 300 shorebird sites in East Asia for the number of species exceeding one percent of the flyway population.¹⁶

The consequences of mudflat loss hit hardest among species that depend most heavily on Yellow Sea stopovers. Birds with more than half of their population relying on Yellow Sea refueling stops declined at roughly five percent per year, while species with lower dependence on the region remained largely stable.¹⁷ Making matters worse, the upper tidal flats, the zones most accessible to feeding shorebirds, provide more than 70 percent of birds’ cumulative foraging time despite covering a proportionally smaller area, and those upper zones are the most vulnerable to coastal development.¹⁸ China’s 2019 inscription of the Yancheng and associated Yellow Sea wetlands on the UNESCO World Heritage list was a significant step, but vast stretches of critical mudflat remain outside any formal protection.

The Hengduan Mountains and China’s Botanical Treasure Chest

Southwestern China, where the Tibetan Plateau drops abruptly into deep river gorges, contains one of the planet’s most astonishing concentrations of plant diversity. The Hengduan Mountains are the epicenter. Phylogenetic analyses show that around eight million years ago, the rate at which new species evolved in the Hengduan Mountains surged dramatically, outpacing the geologically older Tibetan Plateau and Himalayas, where lineage accumulation during the same period was driven more by species arriving from elsewhere than by new species arising locally.¹⁹ In plain terms, the mountains’ rapid uplift created an explosion of new niches, and plants evolved to fill them at an extraordinary pace.

This same region served as a glacial refuge, sheltering species that were pushed out of more northern or exposed areas during ice ages. Ginkgo biloba, the famously ancient “living fossil” tree, survived the Pleistocene glaciations in at least two and possibly three refugia in China. Southwestern China was the primary one, harboring the greatest genetic diversity, with seven of eight identified genetic lineages found there.²⁰ A second refuge existed in eastern China, and genomic resequencing of hundreds of ginkgo trees across the globe confirmed a third potential refuge in southern China.²¹ These refugia were not unique to ginkgo; other ancient species like the dawn redwood and the dove tree survived in the same sheltered valleys.

Karst Caves and Hidden Biodiversity

Southern China’s vast karst landscape, with its limestone towers, sinkholes, and underground rivers, harbors a different kind of biodiversity that rarely makes headlines. Karst microhabitats are characterized by complex structures that serve as critical refuges for specialized species, from cave-adapted fish with no eyes to invertebrates found nowhere else on Earth.²² China’s southwest holds one of the world’s highest concentrations of cave fish species, but these animals live in systems that are extremely sensitive to disturbance. Hydroelectric projects, groundwater extraction, and pollution from the surface can devastate cave ecosystems that took millennia to develop.²³ Because most karst cave species have tiny ranges, sometimes limited to a single cave system, the loss of even one site can mean the extinction of species that science may not have formally described yet.

The Giant Salamander’s Genetic Crisis

The Chinese giant salamander, the largest amphibian on Earth, illustrates how well-intentioned conservation can go sideways. Wild populations have been decimated by poaching and habitat loss, with field surveys finding vanishingly few animals despite extensive searching. Chinese legislation prohibits harvesting wild salamanders, and the government has supported the release of more than 200,000 captive-bred individuals into rivers across the country.²⁴ The problem is that most of those released animals come from a single widely farmed species, and they are being put into rivers outside that species’ natural range. Environmental DNA analysis has revealed a dominance of that farmed species in rivers where it does not naturally belong, indicating genetic homogenization in the wild.²⁵ The releases may be boosting raw numbers in the short term while undermining the genetic diversity that wild populations need to adapt and persist. Researchers have found dead salamanders following known releases, and there is little evidence that released animals establish viable populations where poaching continues.²⁴

The Ecological Conservation Redline

Beyond national parks, China has introduced a broader policy tool called the Ecological Conservation Redline, which aims to ensure no net change in land cover and no net loss of biodiversity or ecosystem services within areas designated as critical for ecological safety.²⁶ The concept operates like a zoning overlay: areas inside the redline face strict limits on development, regardless of who manages them. This supplements the protected-area system by extending restrictions to ecologically sensitive and vulnerable zones that might not qualify as national parks or nature reserves but still perform essential functions like water filtration, carbon storage, or flood control.²⁷

In Shanghai, for instance, applying ecological redline criteria expanded terrestrial protected area by 174 percent, covering about 16 percent of the city’s total land area. The ecosystem-services criteria alone accounted for a 142-percent increase in protected land compared to what traditional conservation designations would have covered.²⁸ The redline policy is especially significant because it applies to urban and peri-urban landscapes where development pressure is fiercest, not just remote wilderness.

Sacred Mountains and Traditional Conservation

Some of the most effective conservation in China has been happening for centuries without any government involvement. Across the Tibetan Plateau and the Hengduan Mountains, sacred mountains protected by local religious traditions harbor forests that outperform even formal nature reserves. In one study of southwestern China, forest cover on Tibetan sacred mountains averaged about 65 percent, significantly higher than both nature reserves and open-access areas at comparable elevations. During a period when deforestation rates in nonsacred areas nearly tripled, sacred mountain forests actually saw their deforestation rate decrease slightly.²⁹

In the Shaluli Mountains region of Sichuan, Tibetan Buddhist beliefs about the equality of all living beings and the spiritual significance of wildlife have translated into de facto wildlife protection. Tibetan communities traditionally abstain from killing wild animals, and as modernization pressures have increased in surrounding regions, local temples and monks have taken an active role in promoting environmental stewardship.³⁰ Sacred forests in the Himalayan portions of China have been shown to support richer bird communities and higher species diversity at multiple spatial scales compared to surrounding non-sacred forests.³¹ The challenge for China’s modern conservation system is finding ways to incorporate these traditional protections rather than overriding them with centralized management that lacks the same local buy-in.

When Greening Creates New Problems

China’s Grain for Green Program, launched in 1999, is one of the largest ecological restoration efforts in human history, converting steep and degraded cropland back to forest and grassland across vast areas of western and central China. The Loess Plateau, once a byword for erosion and ecological degradation, has greened dramatically. But the program has also created unexpected trade-offs, particularly with water. In the Yanhe River Basin, land-use changes driven by the program reduced blue water resources (the water that flows into streams and can be used by people downstream) while increasing green water resources (the water taken up by plants and evaporated).³²

In semi-arid grasslands of Inner Mongolia, restored sites initially showed higher soil moisture than the degraded land they replaced, but soil water content decreased steadily as the restored vegetation matured. By the twelve-year mark, restored grassland had the shallowest rainfall infiltration depth and lowest soil water storage, suggesting a deepening water deficit over time.³³ Across the Loess Plateau as a whole, the massive reforestation has coincided with a persistent and worsening drying trend, highlighting real water stress in a region where water was already scarce.³⁴ The lesson is not that reforestation was a mistake but that planting trees in dry places has hydrological consequences that need to be weighed honestly. Some parts of China’s arid interior may be better served by grassland restoration than by tree planting.

People Inside the Parks

Unlike the American model of national parks as largely uninhabited wilderness, China’s national parks contain millions of residents. Sanjiangyuan alone covers an area the size of England in a region where Tibetan herders have grazed yak for centuries. Balancing conservation with the livelihoods of these communities is arguably the defining challenge of the entire national park system. Research consistently identifies several priorities: aligning traditional livelihoods with conservation goals, limiting new road construction, promoting environmental education, and developing sustainable tourism as an alternative income source.³⁵

In Qinghai’s parks, researchers have argued that the system should set long-term goals while prioritizing near-term improvements in local well-being, rather than imposing conservation restrictions that impoverish the people who live there.³⁶ Some parks have experimented with hiring local herders as paid ecological monitors, a model that provides income while making community members active participants in conservation rather than bystanders with restrictions imposed on them. Whether these approaches can scale across a system spanning such different cultures, economies, and ecosystems remains one of the open questions as China’s parks mature.
