Invasive alien birds in Denmark

Publikation: KonferencebidragKonferenceabstrakt til konferenceForskningpeer review

Avian Introduced Alien Species (IAS) constitute a threat to the integrity of native biodiversity, the economy and human health, so here we briefly review some of the problems posed by such species around the world in relation to bird species in Denmark. A new European Union Regulation on Invasive Alien Species implemented in January 2015 requires a framework for actions to combat alien species, which requires Member States to prevent the spread of alien species, provide early warning and rapid responses to their presence and management
of established alien species where they occur. We show the importance of mechanisms such as DOFs (Danish Ornithological Society, BirdLife Denmark)
Atlas project, Common Bird Monitoring (breeding and wintering species) and DOFbasen to contribute data on the current geographical and numerical distribution of the few serious alien avian species already present in Denmark. We review the status, abundance and distribution of seven critical IAS that do, or have, occurred in Denmark in the last 10 years and conclude that none of these pose a major threat as things stand at the present, although breeding Egyptian Geese (Alopochen aegyptiaca) and Canada Geese (Branta canadensis) potentially give cause for future concern. We underline the need for continued surveillance of all avian IAS through data collection via DOFs monitoring programmes and Aarhus University’s mid-winter, hunting bag and wing surveys. These programmes are essential if we are to continue to effectively monitor the extent and nature of the problems constituted by IAS in support of the Danish Nature Agency in their direct management of alien species problems in this country.
