The Doren project: improving the response curves of habitat types to nitrogen deposition: Phase 2

In 2021, a report was published containing response curves for habitat types to nitrogen deposition, including curves for the underlying species. The curves were estimated by linking vegetation plot information from the EVA-database with modelled nitrogen deposition by EMEP for the Atlantic region of Europe. These curves were partly validated with field data. It was found that this worked well for a large part of the habitat types, however, not for all. Additionally, some species showed unexpected responses. The present study analysed how the curves could be improved, primarily by enhancing the quality of the data and collecting more validation data. Furthermore, we are now able to specify a confidence interval for the response curves.
