摘要

Live capture of grey wolves is an essential but invasive technique used for various ecological and management purposes, carrying potential risks of injury. A range of capture methods is available, each with its own advantages and disadvantages. This study conducted a systematic review of published literature and analyzed original data from 21 wolves captured in Italy between 2019 and 2024 using Fremont™ Humane Foot Snares to compare injury rates across different capture methods. Following PRISMA guidelines, 10 studies were included and assessed using four different injury-classification criteria. Statistical analyses using Fisher’s Exact Test revealed significant differences in injury frequencies among capture methods (p < 0.001 across all criteria). Conventional steel foothold traps caused the highest rate of severe foot and mouth injuries, while foot snare traps and aerial darting resulted in significantly fewer injuries and met international humane trapping standards. These findings emphasize that the choice and handling of capture techniques have a major influence on animal welfare outcomes. Foot snare traps and aerial darting, when properly implemented, appear to be the most humane and reliable capture methods for grey wolves.
