Conservation efforts for the Amur leopard span a network of protected areas across Russia and China, transboundary agreements, anti-poaching patrols, prey restoration, disease management, and planning for possible zoo-to-wild reintroductions. These combined efforts have helped the global wild population climb from roughly 30 individuals in the early 2000s to an estimated 84, though the species remains critically endangered and genetically fragile. The story of Amur leopard conservation is as much about what still needs to happen as about what has already been done.
How the Population Got So Small
The Amur leopard once roamed widely across northeastern China, the Korean Peninsula, and the Russian Far East. Historical records show that it was common throughout large stretches of this range until a sharp contraction began in the mid-twentieth century. A study reconstructing the leopard’s historical distribution found that the decline started from the plains and moved into the mountains, proceeding from northeast to southwest beginning in the 1950s and accelerating dramatically after the 1970s.1PubMed Central. Reconstructing the historical distribution of the Amur Leopard (Panthera pardus orientalis) in Northeast China based on historical records Logging, agricultural conversion, road construction, and uncontrolled hunting of both the leopard and its prey drove the collapse. By the turn of the twenty-first century, the only confirmed breeding population clung to a thin wedge of forest in southwestern Primorsky Krai, Russia, spilling slightly into adjacent Jilin Province, China.
China took several early steps to slow the bleeding. Since 1998, measures including natural forest protection programs, nature reserve construction, bans on wildlife hunting, and bans on commercial forest harvesting have been in place in the northeast.2Scientific Reports. New hope for the survival of the Amur leopard in China These policies gradually improved forest structure and quality, but habitat alone was not enough. The leopard needed coordinated, species-specific action on multiple fronts.
Protected Areas on Both Sides of the Border
The backbone of Amur leopard conservation is a system of protected areas that has expanded considerably in the past two decades. On the Russian side, the Land of the Leopard National Park, established in 2012 by merging several older reserves, covers nearly 3,700 square kilometers of the leopard’s core range. On the Chinese side, the government established the Northeast China Tiger and Leopard National Park, a massive reserve of roughly 14,600 square kilometers that protects habitat shared by both the Amur leopard and the Amur tiger.3Ecology and Diversity. A Transboundary Network of Protected Areas for the Conservation of the Far Eastern Leopard (Panthera pardus orientalis) The Chinese park was designed in part to solve cross-regional and cross-sectoral institutional problems that had fragmented conservation management.4International Journal of Geoheritage and Parks. Study on the zoning of Northeast China Tiger and Leopard National Park
Before the national park system was consolidated, existing protected areas covered less than one-fourth of predicted core habitats for large cats in the region. The establishment of the Northeast China Tiger and Leopard National Park raised that proportion significantly.5Ecosphere. Spatial conservation prioritization for the Amur tiger in Northeast China Still, having a park boundary on a map and having a functioning protected landscape are two different things. Inside the Chinese park, for instance, researchers have found that reducing cattle grazing and other human disturbances is just as important as designating the land.6Biological Conservation. A science-based approach to guide Amur leopard recovery in China A protected area filled with livestock and crisscrossed by logging roads offers far less to a leopard than the designation implies.
The Transboundary “Land of Big Cats”
Because the Amur leopard’s range straddles the Russia-China border, conservation on one side alone cannot secure the species. Leopards do not respect boundaries, and camera-trap surveys have repeatedly shown individuals moving between the two countries. When each country monitored its own side independently, abundance estimates were inflated and less precise. A joint analysis integrating data from both sides found the global population to be about 84 individuals, considerably lower than the sum of the two countries’ separate counts.7Conservation Letters. Transboundary cooperation improves endangered species monitoring and conservation actions: A case study of the global population of Amur leopards That finding alone was a powerful argument for working together.
The latest milestone came in 2024, when Russia and China formally proclaimed the Sino-Russian transboundary protected area called “Land of Big Cats.” This unified zone joins the Russian reserves with the Chinese national park, creating over 17,000 square kilometers of contiguous protected habitat. Researchers estimate this is large enough to support a potential population of at least 300 Amur leopards over the long term, a number that would represent a dramatic improvement in the species’ viability.3Ecology and Diversity. A Transboundary Network of Protected Areas for the Conservation of the Far Eastern Leopard (Panthera pardus orientalis) Whether the population actually reaches that ceiling depends on everything else discussed in this article going right.
Genetic Fragility and the Inbreeding Problem
Eighty-four animals sounds like progress compared with 30, but it is still a desperately small population from a genetic standpoint. Non-invasive genetic sampling, typically from scat and hair collected in the field, has revealed low genetic diversity. One analysis of the Russian population found average expected heterozygosity of just 0.35, a figure consistent with earlier studies showing similarly low diversity. The likely explanation is that the current population descended from very few founders in a short span of time, concentrating a narrow slice of the species’ original genetic variation.8PLoS ONE. Efficient and cost-effective non-invasive population monitoring as a method to assess the genetic diversity of the last remaining population of Amur leopard (Panthera pardus orientalis) in the Russia Far East
Low diversity matters because it increases the risk of inbreeding depression, where harmful genetic variants accumulate and reduce fertility, immune function, and survival. Population viability modeling has shown how much this threatens the Amur leopard’s future. Under different assumptions about inbreeding severity, the probability of extinction over the next century ranged from about 10% in the mildest scenario to nearly 100% in the harshest, if no management actions were taken. Even in the mildest case, the population was projected to shrink over time.9PubMed Central. Contributions of distemper control and habitat expansion to the Amur leopard viability The takeaway is sobering: habitat protection alone cannot save a population this genetically impoverished. Active management, including disease control and potentially introducing new genetic material, is part of the equation.
Disease Management
Canine distemper virus, or CDV, is one of the most serious disease threats. CDV circulates in domestic dogs and can spill over into wild carnivores, including big cats. Because the Amur leopard population is so small, even a handful of deaths from an outbreak could be catastrophic. The same viability modeling that quantified the inbreeding risk found that distemper control was one of the most effective levers for reducing extinction probability.10Communications Biology. Contributions of distemper control and habitat expansion to the Amur leopard viability In practice, this means vaccinating domestic dogs in villages near leopard habitat, monitoring wild carnivore populations for signs of the virus, and planning rapid-response interventions if an outbreak is detected.
Disease concerns also shape the planning around any future reintroduction of zoo-bred leopards. Health screening is a major component of reintroduction protocols. Researchers evaluating the risks have identified CDV, feline immunodeficiency virus, and the bacterium that causes feline chlamydia as key pathogens to screen for before any animal is moved from a zoo to the wild. They noted that many of the most expensive and complex diagnostic tests can be performed while animals are still in zoo facilities, which have better access to veterinary laboratories than field stations in the Russian Far East. Significant data gaps remain, however, about pathogen prevalence in the wild population itself, which makes predicting how introduced animals would fare uncertain.11PubMed.

Anti-Poaching Patrols and Snare Removal
Poaching, both of leopards themselves and of their prey, remains a persistent threat despite legal protections. In the Chinese portion of the range, continuous winter patrols using the Spatial Monitoring and Reporting Tool, known as SMART, have operated from 2013 through at least 2020. These patrols record wildlife sightings and systematically remove wire snares from the forest.12Biological Conservation. Habitat accessibility and snares impact large cats and their prey in Northeast Tiger and Leopard National Park, China Snares are cheap, easy to set, and indiscriminate. They are typically placed by local villagers to catch ungulates for meat, but a leopard or tiger that wanders into one can be injured or killed. Research from the national park has confirmed that snare density and the accessibility of habitat to humans are significant factors affecting where large cats and their prey are found, reinforcing the value of sustained patrol effort.
SMART patrols are important not just for removing snares but for generating the data that guides management decisions. When patrol teams log every wildlife detection, sign of human activity, and piece of removed equipment, managers can identify problem areas and shift resources accordingly. It is one of the more tangible, boots-on-the-ground tools in the Amur leopard conservation toolkit.
Rebuilding the Prey Base
A leopard cannot persist without enough to eat, and prey availability has been a limiting factor for decades. The main prey species in the Amur leopard’s range are sika deer, roe deer, and wild boar. In southwestern Primorsky Krai, recent monitoring found that although wild boar and roe deer populations had declined, a growth in sika deer numbers kept the total ungulate population at roughly 33,000 animals in 2023, a level considered sufficient to support the growing populations of both the Amur leopard and the Amur tiger.13Russian Journal of Ecosystem Ecology. Changes in the Number of Wild Ungulates in the Southwest Primorskiy Province, Russia
On the Chinese side, the priority has been reducing competition between livestock and wild ungulates for food and space. Cattle grazing inside leopard habitat displaces wild deer, degrades the forest understory, and brings the risk of disease transmission. Conservation planners have emphasized progressively minimizing cattle and human impacts on the forest alongside active habitat expansion for large ungulates, whose presence is essential for leopard occupancy.6Biological Conservation. A science-based approach to guide Amur leopard recovery in China Some areas within the Chinese national park have implemented livestock buyout and relocation programs to reduce grazing pressure, though full removal across the park’s vast area is a slow process.
Reintroduction Planning
There are currently around 200 Amur leopards in zoos worldwide, managed through coordinated breeding programs in Europe and North America. These captive populations represent a potential genetic reservoir for the wild. A proposed reintroduction plan envisions selecting animals from these programs and releasing them into suitable habitat, most likely in areas of Russia or China where the species formerly occurred but is now absent. The goal would be to establish a second wild population, reducing the risk of a single catastrophic event wiping out the only remaining one.
That said, the plan still faces major unresolved questions about logistics, site selection, disease screening, and post-release monitoring. A review of the proposed program noted that while the objective of using zoo-bred animals is clear, effectiveness remains uncertain given the complexity of reintroducing a large carnivore into a landscape shared with people, livestock, and other predators.14Topics in Companion Animal Medicine. A review of the proposed reintroduction program for the Far Eastern leopard (Panthera pardus orientalis) and the role of conservation organizations, veterinarians, and zoos Captive-bred big cats often lack the hunting skills and wariness of humans that wild-born animals develop, raising concerns about whether they could survive and reproduce after release. No reintroduction has yet taken place, but the groundwork continues.
Living with Tigers and Bears
The Amur leopard shares its remaining habitat with the Amur tiger, a larger predator that can dominate the same prey base and occasionally kill leopards. Understanding how these two species coexist spatially is important for managing the landscape. Research using camera traps and spatial modeling in the region has found that Amur leopard habitat selection is influenced by the density of other leopards, the presence of bears, elevation, proximity to rivers, and forest type. The leopard’s presence was positively associated with larch forests and Korean pine proximity.15PubMed Central. Intra‐ and Interspecific Spatial Temporal Interactions Drive Habitat Selection of Three Sympatric Top Predators Interestingly, leopard presence was positively correlated with bear density, suggesting the two species select similar habitats rather than avoiding one another.
For conservation managers, this means that protecting leopard habitat also benefits tigers and bears, and vice versa. But it also means that as tiger numbers grow in the national park, competition with leopards could intensify in certain areas. Monitoring spatial overlap and adjusting management zones as both populations expand is an ongoing challenge that will only become more complex if the leopard population reaches the hundreds.
The Korean Peninsula Question
One of the more ambitious and politically complex ideas in Amur leopard conservation involves the Korean Peninsula. Historically, the leopard’s range extended into what is now North Korea, and forests in the Tumen River basin along the China-North Korea-Russia border could theoretically serve as a corridor connecting the current population to suitable habitat further south. Researchers have identified the Mijiang region on the Chinese side of this border as a critical link, but it is currently degraded by grazing, mining, farming, logging, and infrastructure development. Restoring it to serve as a functional corridor would require halting and reversing these disturbances, which in turn demands inter-governmental and international cooperation that does not currently exist in any meaningful form.16PubMed Central. Transboundary Cooperation in the Tumen River Basin Is the Key to Amur Leopard (Panthera pardus) Population Recovery in the Korean Peninsula
The geopolitical barriers here are obvious. North Korea’s isolation makes any cooperative conservation agreement extremely difficult to negotiate or enforce. Yet from a purely ecological perspective, the Korean Peninsula represents one of the few directions in which the leopard’s range could expand substantially. If the species is ever to achieve long-term viability without permanent reliance on intensive management, it will likely need more habitat than even the newly proclaimed Land of Big Cats can offer. The Korean corridor remains a distant goal, but researchers continue to model its potential so that if political circumstances change, a scientifically grounded plan will be ready.
Fire and Forest Degradation
Repeated burning is a less dramatic but persistent threat to Amur leopard habitat. In parts of the range, frequent fires, often set by people to clear land or manage grazing areas, prevent the forest understory from regenerating. Over time, this converts closed-canopy forest into open grassland, which Amur leopards cannot use effectively. The leopard is a forest specialist that depends on dense cover for stalking prey, and open landscapes offer neither the ambush opportunities nor the prey density it needs. Forest fire management, including firebreak construction and enforcement of burning restrictions, is an active but imperfect part of the conservation strategy in both Russia and China.
Ecological Thresholds and Future Risks
Conservation planners are increasingly thinking about the Amur leopard in terms of ecological thresholds: tipping points beyond which a population or its habitat shifts into a degraded state that is difficult to reverse. A review of threshold dynamics for large carnivores in the region highlighted that changes in climate, vegetation, prey, competitors, and human disturbance do not act in isolation. Interactions between these factors can amplify responses in unpredictable ways. For instance, a mild decline in prey density combined with a moderate increase in human disturbance might individually be tolerable, but together they could push a local leopard population below a point of no return.17Global Ecology and Conservation. Ecological thresholds and large carnivores conservation: Implications for the Amur tiger and leopard in China
Climate change adds another layer of uncertainty. Warming temperatures are already shifting vegetation zones and altering snowfall patterns in the Russian Far East. How these changes will reshape prey distributions, fire regimes, and disease dynamics over the coming decades is not well understood. The Chinese government’s multi-stage plan for expanding the Amur leopard’s range into the broader Changbaishan Mountain landscape reflects an awareness that the species needs room to move as conditions shift.6Biological Conservation. A science-based approach to guide Amur leopard recovery in China Whether expansion happens fast enough to stay ahead of the threats is the central tension in Amur leopard conservation today. The infrastructure of protection, from transboundary parks to patrol teams to genetic monitoring, is more robust than it has ever been. The question is whether it is robust enough.
