Impacts of nitrogen on vegetation: Final Report Work Package 5 Defra Contract AQ0810 The UNECE International Cooperative Programme on Vegetation

In this study the following scientific objectives were addressed:

1) To assess the evidence for the impacts of nitrogen (N) on vegetation in areas of Europe with high N
deposition by:

a) Identifying locations of sensitive ‘Heathland’ and ‘Grassland’ EUNIS classes with likelihood
of exceedance of empirical critical loads of N for the EMEP domain (SEI York);

b) Developing a meta-database describing National surveys on N impacts on vegetation and
summary of main findings (SEI-York and CEH Bangor);

2) To analyse spatial trends in the N concentration of mosses in relation to N deposition maps and
comparison with critical load exceedances, both at the UK and EMEP scale (CEH Bangor).
