A lower number forces harder choices about what we protect and how much we hunt.
Across sub-Saharan Africa, the leopard — one of the continent's most adaptable and enduring predators — has grown far rarer than the world assumed, its retreat shaped by the familiar forces of human expansion, habitat loss, and the slow erosion of the wild places it needs to survive. Scientists at Nottingham Trent University have now placed a number on that absence: between 45,000 and 143,000 individuals remain, well below prior estimates, and hunting quotas in more than half the countries assessed are taking more than the populations can sustain. Yet the same research that maps the decline also charts a path toward recovery, reminding us that the distance between loss and restoration is often a matter of political will and precise, timely action.
- Leopards have disappeared from over 41% of their historical range, and the populations that remain are far smaller than conservation policy has assumed — a dangerous mismatch between data and reality.
- Trophy hunting quotas in more than half the assessed countries exceed sustainable levels, drawn from population figures now known to be both outdated and inflated, meaning legal harvests are quietly accelerating the decline.
- The species clings to survival in protected areas, but outside those boundaries — where agriculture, livestock, and human settlement dominate — leopards are largely absent, their prey depleted and their habitat fragmented.
- Western Africa represents a critical blind spot: leopards may still persist there, but so little scientific data exists that conservation efforts have barely reached the region.
- Researchers are calling for immediate quota revisions, camera trap surveys in data-poor zones, habitat restoration to rebuild prey populations, and targeted reintroductions where conditions allow — a concrete, location-specific recovery roadmap.
A new study from Nottingham Trent University has delivered a stark reassessment of one of Africa's most iconic predators: far fewer leopards exist across sub-Saharan Africa than previously believed. Published in the Journal of Applied Ecology, the research estimates between 45,000 and 143,000 leopards remain in the wild — significantly lower than earlier figures — though it also finds that with meaningful protections in place, the continent could support up to 176,000 within the species' historical range.
The leopard's decline has been driven by habitat destruction, the collapse of prey populations, and trophy hunting, erasing the species from more than 41% of the areas it once occupied. To fill a long-standing data gap, the Nottingham Trent team assembled decades of population records and built a predictive model weighing habitat quality, human pressure, and prey availability. What emerged was a portrait of a species surviving in fragmented pockets — thriving inside protected areas, but largely absent from landscapes shaped by farming and settlement, where ungulate populations have been depleted and leopards have little left to sustain them.
Perhaps the study's most urgent finding concerns trophy hunting. Researchers estimate only 2,800 to 8,700 adult male leopards live outside protected areas in countries where hunting is permitted — a perilously thin population to harvest from. Yet current international quotas in more than half those countries exceed what scientists consider sustainable, based on population figures now understood to be both outdated and inflated.
Dr. Antonio Uzal stressed that the absence of reliable numbers has long undermined conservation planning, while co-author Dr. Julien Fattebert called for an immediate overhaul of hunting quotas alongside regular field surveys. Lead author Kalpapran Patowary highlighted western Africa as a critical gap — a region where leopards may still survive but remain nearly invisible to science, and where conservation resources are most urgently needed.
The researchers recommend camera trap deployments in data-poor areas, habitat restoration to rebuild prey populations, and reintroductions where feasible. The study is both a warning and a map: the leopard has not yet disappeared from sub-Saharan Africa, but the window for meaningful action is closing, and what happens next depends largely on whether governments choose to act on what the science now clearly shows.
A new study from conservation scientists at Nottingham Trent University suggests that leopards are far scarcer across sub-Saharan Africa than anyone realized—and that the animals we thought were out there may not actually be. The research, published in the Journal of Applied Ecology, estimates between 45,000 and 143,000 leopards remain in the wild today, a figure substantially lower than previous guesses. But the study also carries a quieter, more hopeful message: if the right protections were put in place, the continent could theoretically support as many as 176,000 leopards within their historical range.
The leopard's retreat has been relentless. The species has vanished from more than 41 percent of the areas where it once roamed, driven out by habitat destruction, the collapse of prey populations, and trophy hunting. Yet governments and conservation organizations have lacked reliable data on how many animals actually remain—a gap that has made it nearly impossible to plan recovery efforts with any precision. The Nottingham Trent team set out to fill that void by assembling decades of population data from across sub-Saharan Africa and building a model that could predict current leopard numbers based on habitat quality, human pressure, and prey availability.
What emerged from the analysis was a portrait of a species clinging to survival in fragmented pockets. Leopards thrive in protected areas where ecosystems remain intact, but they struggle dramatically in landscapes dominated by human settlement and agriculture. High livestock numbers, nearby villages, and farmland all correlate with leopard absence. The animals need ungulates—deer, wild pigs, and similar prey—to survive, and where those populations have been depleted, leopards disappear. The researchers caution that their estimates are not precise counts; much of the underlying data comes from protected areas, which tend to be healthier for leopards than the working landscapes where people live and hunt.
The study raises an alarm about trophy hunting that cannot be ignored. Current international hunting quotas in more than half of the countries assessed exceed what scientists consider sustainable. The researchers estimate that only 2,800 to 8,700 adult male leopards live outside protected areas in countries where trophy hunting is permitted—a vanishingly small population to be harvesting from at all. Those quotas, the authors argue, are based on population figures that are both outdated and inflated, meaning hunters are taking more animals than the populations can bear.
Dr. Antonio Uzal, an associate professor at Nottingham Trent, emphasized that the lack of solid numbers has crippled conservation planning. "Our work provides practical guidance for conservation and clear, location-specific targets for leopard recovery," he said, noting that the research shows where protection efforts will have the greatest impact both inside and outside protected areas. His co-author, Dr. Julien Fattebert of Vilnius University and Nelson Mandela University in South Africa, called for an urgent overhaul of hunting quotas based on current data, alongside regular field surveys to prevent further decline.
The path forward is specific and actionable. In areas outside protected reserves where leopard numbers remain unclear, researchers recommend deploying camera traps to get an accurate count and restoring habitat to support prey populations. Reintroductions should be considered where conditions allow. The study also highlights western African countries as particularly underrepresented in existing data—regions where leopards may still survive but remain largely invisible to science. Kalpapran Patowary, the study's lead author and a doctoral student at Clemson University, stressed that conservation resources should be concentrated in these overlooked areas where leopards persist but are poorly understood.
The research offers a rare combination: a sobering assessment of how few leopards remain, paired with a concrete roadmap for recovery. The animals have not yet vanished from sub-Saharan Africa, but the window for action is narrow. Whether governments will act on these findings—revising hunting quotas, protecting habitat, restoring prey populations—will determine whether the leopard's decline continues or reverses.

Why does it matter that we now have a lower estimate of leopard numbers than we thought before?
Because conservation is about precision. If you think there are more animals than there actually are, you set quotas and protections based on a false sense of security. You hunt more than the population can sustain. You protect less land than you need to. A lower number forces harder choices.
The study says Africa could support 176,000 leopards if conditions improved. That's higher than the current estimate. How do we get there?
It's not automatic. That number assumes habitat is restored, prey populations recover, human-wildlife conflict is managed, and hunting is controlled. It's a theoretical ceiling, not a promise. It requires sustained, coordinated effort across multiple countries.
You mentioned that most of the data comes from protected areas. Why is that a problem?
Protected areas are the leopard's refuge, but they're not the whole story. Leopards also live—or used to live—in working landscapes where people farm and settle. We know less about those populations because they're harder to study and often in conflict with humans. That's where the real conservation challenge lies.
The study says hunting quotas are too high in more than half the countries assessed. What happens if those quotas aren't revised?
The decline accelerates. You're removing breeding males from an already fragmented population. The animals outside protected areas—the ones most vulnerable anyway—get hunted harder. Recovery becomes even less likely.
Western Africa is mentioned as underrepresented. What does that mean for leopards there?
It means we don't know how many are left. They could be present in numbers we haven't documented, or they could be on the edge of local extinction. Either way, they're invisible to policy. That invisibility is dangerous because it means no one's planning for their protection.
