Camera trap technology has transformed wildlife monitoring for wild tigers, enabling population estimates and individual identification with minimal disturbance — a welfare-positive advance in conservation science.
Camera trap technology represents an ideal from an animal welfare perspective: it generates high-quality conservation data with essentially no direct welfare cost to study subjects. Tigers moving through their natural range encounter camera stations without behavioral disruption beyond occasional curiosity; no capture, restraint, or chemical immobilization is required. This contrasts sharply with intensive research methods requiring capture — anesthetic procedures that carry mortality risk of 0.5-1% even in expert hands, collar attachment that may cause local skin reaction and behavioral changes, and the documented stress of handling. The welfare case for non-invasive monitoring technology extends beyond tigers to all wildlife research: where camera traps, acoustic monitoring, environmental DNA sampling, and remote sensing can answer conservation questions, their use should be preferred over methods requiring physical contact with wild animals.
