Abundance and distribution of birds and marine mammals in Jammerbugten in 2012 and 2013

Publikation: Bog/antologi/afhandling/rapportRapportRådgivning

In 2012 Vattenfall A/S, on behalf of the Environmental Group concerning
offshore wind farms in Denmark, commissioned Aarhus University, DCE
(Danish Centre for Environment and Energy), to conduct a total of five aerial
line transect surveys in Jammerbugten off the west coast of northwest Jutland.
The results of these five aerial surveys conducted in 2012 and 2013 in Jammerbugten
are presented in this report. The objective was to map the distribution
of all birds and mammals present in the area.
A total of 24 bird species were recorded in the study area. The most common
species was Herring Gull. Birds were recorded throughout the survey area.
Common Scoters and Common Eiders were found in the shallow coastal waters
while Razorbills and Guillemots were found in the deeper areas to the
north. Gulls were recorded throughout the survey area.
No attempt has been made to estimate total numbers or perform spatial
modeling of distribution from this data set. The relatively low number of observations
prevented such analyses. Two of the five surveys were conducted
as part of the national waterbird monitoring program. A survey conducted
on 22 February 2012 will be part of the national 2012 mid winter waterbird
survey and a survey conducted on 31 August 2012 will be part of the national
2012 summer waterbird survey. The summer survey was mainly focused
on moulting waterbirds. Within this wider geographical perspective these
two surveys contribute to modelled density surfaces, including the Jammerbugt
area, for selected species.
