Description

This map shows the extent of exceedance of the critical deposition value (KDW) for acidification of the European protected habitats in Flanders in the shades of yellow-orange-red. The green areas are the habitats in which the KDW are (currently) not in exceedance. The grey areas are the habitats that are not sensitive to the effect of airborne acidification (> 2400 Zeq/ha.year). The KDW is the amount of acidifying deposition (acid equivalent per hectare per year) for a given ecosystem below which, according to current scientific knowledge, there will be no significant change in biodiversity in the long term. A specific KDW has been determined for each habitat type. Not every type of nature is equally susceptible to acidification. The exceedance map has been drawn up by VITO on the basis of the following data: (A) The modelled depositions of acidifying substances based on VLOPS20, the version of the VLOPS model in 2020 that uses emission and meteorological data of the year 2017. This is a raster layer with a resolution of 1 km2; (B) The BWK habitat map version 2020; and (C) The appropriate extension sites for European protected habitats and species: the so-called provisional search areas for conservation objectives - version 0.2 (ANB, 2015).
