Camera traps are transformative tools for wildlife research but can disturb animals through light, noise and scent, making welfare-conscious deployment essential for ethical monitoring.
Camera trapping offers a minimally invasive approach to wildlife monitoring compared to capture-based methods, but its welfare footprint is not zero. Flash disturbance of nocturnal species, scent contamination altering predator-prey dynamics and chronic sensitisation of animals to monitoring points all represent welfare considerations. At breeding sites including dens and nests, even well-designed monitoring can cause abandonment if deployment timing or positioning is insensitive. Research ethics in wildlife science is evolving to treat camera trap welfare impact with increasing seriousness, requiring deployment protocols that minimise disturbance frequency, use infrared rather than flash technology and avoid sensitive site proximity during critical breeding periods.
