Abundance of waterbirds in the breeding season - wading feeders 2018 HOLAS 2
This dataset contains core indicator results for the bird species breeding in the Baltic Sea area by assessing fluctuations in abundance, visualized for wading feeders.
Quantitative regional thresholds are used to evaluate if the core indicator achieves good status. The indicator performs status evaluations by aggregating annual single species index values for all waterbird species and on the basis of aggregated indices for five species groups (wading feeders, surface feeders, pelagic feeders, benthic feeders, grazing feeders). 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).

Following a data call in May 2017, breeding bird data of 30 species for the years 1991-2016 were supplied by authorities from Contracting Parties of HELCOM, except Russia and Lithuania. Breeding bird abundance was reported in numbers of breeding pairs, but Swedish data referred to numbers of males and individuals. The use of different units did not cause problems, because calculations are done on the basis of population indices rather than on population sizes.
The indicator performs status evaluations by aggregating annual single species index values for all waterbird species or on the basis of aggregated indices for five species groups (wading feeders, surface feeders, pelagic feeders, benthic feeders, grazing feeders). Data sets consisted of site code, year, species and abundance. Data were supplied for a total of 1920 sites, but each species had different numbers of sites used in the analysis. The overall confidence of the indicator is currently intermediate.
