Birds at Risk: The Importance of Canada’s Boreal Wetlands and Waterways

This report looks at three natural areas in the boreal forest that are critical for birds,
but that are coming under pressure from industry, hydropower, and climate change.
We discuss some strong policy steps governments must take in order to protect the
watery forest and the great biodiversity of birds it supports.

Waterbird Populations and Pressures in the Baltic Sea

This report outlines the results of the internationally coordinated census of wintering waterbirds in the Baltic Sea 2007-2009 undertaken under the SOWBAS project (Status of wintering Waterbird populations in the Baltic Sea). The estimated total number of wintering waterbirds was 4.41 million compared to 7.44 million during the last co-ordinated census 1992-1993. Despite the general declines stable or increasing populations of herbivorous species were recorded.

While benthic carnivores with a coastal distribution have either shown moderate declines, stable or increasing populations.
