This dataset contains core indicator results for the bird species breeding in the Baltic Sea area by assessing fluctuations in abundance, visualized for benthic feeders.Quantitative regional thresholds are used to evaluate if core indicators status is GES (good environmental status) or sub-GES (sub- good environmental status). Good status is achieved when the abundance of 75% of the considered species of a species group does not decline by more than 30% (20% in species laying only one egg per year) compared to a baseline during the reference period 1991-2000.

This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas).

Attribute information:

"HELCOM_ID" = ID of the HELCOM scale 3 assessment unit

"level_2" = Name of scale 2 HELCOM assessment unit

"level_3" = Name of scale 3 HELCOM assessment unit

"Area (km2)" = Area of HELCOM assessment unit

"coastal" = HELCOM ID of the coastal areas

"open_sea" = Name of scale 2 HELCOM open sea assessment unit

"Abundance" = Assessed parameter

"Wading feeders" = Results for the category

"Wading feeders status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)

"Surface feeders" = Results for the category

"Surface feeders status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)

"Pelagic feeders" = Results for the category

"Pelagic feeders status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)
