The polecat's recovery across England from its Welsh stronghold is one of Britain's lesser-known wildlife success stories. Understanding the threats to continued recovery helps sustain the population.
Polecat welfare in recovering populations is primarily threatened by road mortality as newly established animals navigate unfamiliar road networks. Each road casualty represents a loss from a still-fragile recovering population where genetic diversity is important. Non-target trapping adds welfare costs to individual polecats caught in gear set for other species. Hybridisation with ferrets creates a genetic welfare consideration at the population level - the long-term persistence of genetically distinct polecats depends on reducing ferret escape rates.
