Offshore seaduck counts in the Baltic
During 2007- 2009 offshore-counts of the entire Baltic were organized
within the SOWBAS project to
follow up the development since the first total surveys of the Baltic in
1992/93. Counts in Sweden have been continued in 2010 and 2011.
The Longtailed Duck has shown a dramatic decrease in numbers during
recent years. The estimated population in Swedish waters have decreased from
1.4 mill. to about 0.5 in 2009.
The results of the Swedish counts are found on the link below.
