The Barnacle Goose (Branta leucopsis) in the archipelago of southern Finland – population growth and nesting dispersal
Urbanization and other human activities can lead to decreasing animal populations in nearby areas. The impact of human activities may vary depending on the characteristics of the areas and region or on the strength of the disturbance. We investigated forest bird population changes in an EU Natura 20...

Urbanization and other human activities can lead to decreasing animal populations in nearby areas. The impact of human activities may vary depending on the characteristics of the areas and region or on the strength of the disturbance. We investigated forest bird population changes in an EU Natura 2000 area during the construction of the new Helsinki Vuosaari Harbour in southern Finland in 2002-2011 as part of an environmental impact assessment. We evaluated whether the changes observed were linked with the harbour construction work by comparing the populations at sites near the development with those corresponding values obtained from national common bird monitoring in southern Finland.
