Protected areas safeguard important refuges for wildlife, but a major new analysis suggests they cover only a small fraction of the ranges used by the world’s large carnivores – leaving many species exposed to habitat loss, persecution and other human pressures.
Published in Science Advances and reported by Mongabay, the study mapped the distributions of dozens of carnivore species against the global network of protected areas and human activity. The authors found that for many predators – from wolves and big cats to smaller specialist carnivores – significant parts of their ranges lie outside formally protected boundaries, where threats are far higher.
That shortfall has practical consequences. Outside protected spaces, carnivores face farmland expansion, infrastructure, livestock encroachment and conflict with people, as well as illegal killing and incidental mortality such as snaring. The paper shows these pressures are often concentrated close to protected-area edges, meaning that merely expanding park coverage without tackling threats at boundaries will do little to secure predator populations.
Small carnivores, such as Stoats, play important roles in their ecosystems and are experiencing declines parallel to those of large carnivores globally (Paul Reed).
Predator protections
The authors put the finding bluntly: protecting more land is necessary but not sufficient. To safeguard carnivores long-term, conservation must combine well-sited protected areas with measures that reduce threats in surrounding landscapes. That includes improving habitat connectivity to allow animals to move between reserves, stricter controls on poaching and snaring, better livestock-protection measures, and targeted management in key unprotected strongholds.
The study also highlights the unevenness of protection. Some species have much of their remaining habitat inside reserves, while others – especially wide-ranging or human-tolerant species – depend heavily on unprotected lands. That means conservation plans need to be species-specific, prioritising areas where interventions will most reduce extinction risk.
Researchers call for smarter use of limited conservation funds. Rather than blanket expansion, they recommend identifying and securing the most important remaining patches for carnivores, and investing in threat-reduction where it will deliver the biggest gains. They also stress the role of local communities and landowners – mitigating human-predator conflict and offering incentives for coexistence are central to any successful strategy.
