SURVEY OF WINTERING WATERBIRDS IN THE BALTIC 2007-11

THE SWEDISH PART

 

 

The first ever total survey of wintering waterbirds in the Baltic sea was undertaken in 1992/93, using a combination of aerial surveys, boat counts and ground counts. In 2007 - 2009 a second survey (SOWBAS) was undertaken in cooperation with the different Baltic states with the main aim to elucidate possible changes since the first survey. The 2007 - 2009 survey was mainly planned as aerial surveys and with had the aim to cover all areas in 2007 and 2008, but due to weather it had to be extended to 2009 before completion. The report from the SOWBAS project will be published later this year.

During the same time Naturvårdsverket in Sweden decided to make a larger study of the seabirds wintering in Swedish waters and to investigate the possibilities to include these important groups in the regular mointoring programs for Swedish birdlife. The counts were therefore continued in 2010 and 2011. This material has now been analyzed and you will find some results of the surveys if you follow the links to the different offshore seaducks below. There you will also find infomration about survey methods and areas covered.
