Research overview: snaring and its impacts on felids

Wire snares are among the most pervasive and indiscriminate threats to big cats, killing or maiming tigers, leopards, lions, and other predators directly and decimating the prey populations they depend on. This overview surveys research on the scale and consequences of snaring, particularly in Southeast Asia and parts of Africa, where industrial-scale snare lines empty forests and savannas of wildlife. Studies quantify snare densities, document cats killed or injured, and link snaring to the empty-forest phenomenon and to regional carnivore collapse. Researchers evaluate responses including snare-removal patrols, detection methods, and addressing the demand and bushmeat economies that drive snaring. The overview frames snaring as a crisis that can undermine even well-protected reserves, since snares set for any wildlife also catch big cats and strip away their food. Combating snaring is therefore central to anti-poaching strategy for felid conservation.
