Scotland holds the majority of the UK's small breeding wigeon population, with conservation dependent on upland loch and bog habitat protection.
Scottish breeding wigeon exist in small numbers where habitat quality directly determines breeding success and individual duckling survival. Drainage of upland bogs reduces invertebrate food needed for duckling growth. Mink predation causes both direct predation and disturbance stress that suppresses breeding. Habitat restoration and mink management at key breeding sites directly improves individual wigeon welfare and population sustainability.
