Cousin German moth conservation
The Species Action Plan produced for the Cousin German moth as part of the UK Biodiversity Action Plan (UK BAP) aims to maintain the present range of the species. Some populations are located within existing Sites of Special Scientific Interest (SSSIs) and nature reserves. Conservation action targeted at other threatened species that occur within Scottish pine forests, such as the Scottish wood ant Formica aquilonia, will also benefit the Cousin German moth (2).Top
