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.

This report presents hunter activity and harvest estimates from the HIP surveys for the 2004-05
and 2005-06 hunting seasons. These estimates are preliminary, pending (1) final counts of the
number of HIP registrants in each state each season, and (2) complete audits of all survey
response data.
Since the 1952-53 hunting season, the U.S. Fish and Wildlife Service (FWS) has conducted a

Migratory Bird Hunting Activity and Harvest 2005-2006

Since the 1952-53 hunting season, the U.S. Fish and Wildlife Service (FWS) has conducted a
survey of Federal Duck Stamp purchasers to estimate waterfowl hunter activity and harvest in
the United States. That survey was conducted annually through the 2001-02 hunting season,
after which it was replaced by a new migratory game bird harvest survey system. In 1992, the
FWS and State Fish and Wildlife Agencies (States) established the Migratory Bird Harvest
Information Program (HIP), which was fully operational nationwide by 1999 (Elden et al. 2002).
