Camera Traps and Wildlife Monitoring Welfare

Camera traps and remote sensing technology have transformed wildlife monitoring with fewer welfare impacts than traditional methods.

Key Facts

Camera traps capture images of rare species without capture or handling stress
White-flash cameras may disturb some nocturnal species compared to infrared
GPS satellite collars require capture and fitting that causes short-term stress
Environmental DNA sampling from water or air requires no animal contact at all
Acoustic monitoring can detect and identify species from vocalisations without disturbance

Welfare Considerations

Traditional wildlife monitoring involving trapping, handling, and marking causes acute stress, injury risk, and potential long-term behavioural changes. Camera trapping eliminates most of these harms but may itself create disturbance through flash, scent, or unusual object presence. The development of eDNA and acoustic monitoring represents welfare advances over physical capture methods. Passive monitoring methods should be preferred wherever they provide equivalent data quality.

What You Can Do

Support wildlife recording schemes that use non-invasive monitoring methods
Advocate for welfare-first consideration in wildlife research protocol design
Back funding for eDNA and acoustic monitoring technology development
Support training in minimal-impact fieldwork techniques
Engage with wildlife research consultations to prioritise non-invasive methods
