Flood events cause mass displacement and death among wild and domestic animals, with welfare impacts that scale with the frequency and severity of flooding events.
Flood welfare harms are both acute (drowning, hypothermia, injury) and prolonged (starvation, disease, displacement). Wild animals lose burrows, nests, and foraging habitat simultaneously. Livestock trapped by rising water face drowning or prolonged standing in contaminated floodwater, causing disease and foot problems. Post-flood disease (leptospirosis, salmonellosis) spreads through displaced animal populations. Emergency responses that include animals save both animal and human welfare outcomes.
