Abundance of waterbirds in the wintering season 2018
Short description
This core indicator evaluates the status of abundance of wintering waterbirds in the Baltic Sea region. The wintering waterbirds are considered to reflect good status when at least 75% of the considered species deviate less than 30% downwards (species laying more than one egg per year) or 20% downwards (species laying one egg per year) from the baseline condition during the reference period 1991-2000. This dataset displays the result of the indicator in HELCOM Assessment Scale 1 (Whole Baltic Sea). Attribute information: "level_1" = Name of scale 1 HELCOM assessment unit "AULEVEL" = Assessment unit level used for the indicator "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "Eurasian Teal" = Results for Eurasian teal "Black-headed Gull" = Results for black-headed gull "Common Gull" = Results for common gull "Great Black-backed Gull" = Results for great black-backed gull "Herring Gull" = Results for herring gull "Smew" = Results for smew "Goosander" = Results for goosander "Red-breasted Merganser" = Results for red-breasted merganser "Great Crested Grebe" = Results for great crested grebe "Great Cormorant" = Results for great cormorant "Common Pochard" = Results for common pochard "Tufted Duck" = Results for tufted duck "Greater Scaup" = Results for greater scaup "Steller's Eider" = Results for Steller's eider "Common Goldeneye" = Results for common goldeneye "Mute Swan" = Results for mute swan "Whooper Swan" = Results for whooper swan "Bewick's Swan" = Results for Bewick's swan "Mallard" = Results for mallard "Northern Pintail" = Results for northern pintail "Eurasian Coot" = Results for Eurasian coot "Eurasian Wigeon" = Results for Eurasian wigeon

Lineage
The current evaluation is based on national monitoring data from coastal mid-winter counts (International Waterbird Census organized by Wetlands International) from all HELCOM Contracting Parties. Data for the years 1991-2015 were supplied by national dataholders following a data call in March 2016. Data sets consisted of site code, year, species and abundance (bird numbers). Data were supplied for a total of 1778 sites, but each species had different numbers of sites used in the analysis. We acknowledge the E-OBS dataset from the EU-FP6 project ENSEMBLES (http://ensembles-eu.metoffice.com) and the data providers in the ECA&D project (http://www.ecad.eu). The confidence of the evaluations is estimated to be intermediate.
