Snaring is one of the most indiscriminate and welfare-harmful methods of wildlife capture. The injury, fear, and prolonged suffering caused by snares affects both target and non-target species globally.
Snare injuries cause among the most severe acute and chronic welfare harms in wild animal populations. An animal caught in a wire snare pulls against the wire as it struggles, progressively tightening the loop and causing deep cuts that penetrate to bone. Struggling continues until exhaustion, injury, or death. Animals that survive snare entanglement by gnawing off their limb face subsequent infection, phantom pain, and reduced survival in the wild. The stress of sustained entrapment over hours or days adds psychological suffering to physical injury. The indiscriminate nature of snares means endangered species including gorillas, elephants, and tigers are regularly injured or killed. Snare removal patrols represent a welfare intervention with direct individual benefit alongside conservation outcomes.
