Wild European rabbits live in complex social warren systems with established hierarchies and cooperative behaviors, with warren disruption by disease, predation, and habitat loss causing welfare impacts at individual and group levels.
Wild rabbit welfare at the warren level reflects the social complexity of this often-underestimated species. Disease outbreaks like RHD cause mass mortality events that eliminate entire social groups, with survivors losing companions and warren social structure simultaneously. Predator disturbance causes repeated physiological stress responses in warren-dwelling animals, particularly during the breeding season when females with kittens in burrows are most vulnerable. Habitat fragmentation creates population isolation effects similar to those in larger mammals - reduced genetic diversity, increased disease susceptibility, and reduced ability to recover from population crashes. Conservation approaches that protect warren sites and reduce disease pressure benefit both population persistence and individual welfare.
