Common frogs face multiple welfare threats during their spring breeding season including road mortality, spawn-site degradation, and ranavirus disease.
Road casualties during spring migration cause acute trauma and death for thousands of frogs at regular crossing points. Ranavirus infection causes severe internal haemorrhage and death in pond populations. Both are preventable or reducible - frog patrols with buckets at crossing points and biosecurity to prevent ranavirus spread between sites are practical welfare interventions. Garden pond creation provides safe breeding habitat.
