International audience. Reduction in the species richness of acid grasslands along a gradient of atmospheric nitrogen (N) deposition has previously been demonstrated in the UK (Stevens, Dise, Mountford, Gowing, Science 303:1876–1879, 2004). Further surveys of acid grasslands in the UK confirm this relationship. This chapter reports an examination of the relationship across the Atlantic region of Europe. Examining the cover of functional groups across this gradient reveals that forb cover is strongly reduced along the gradient of N deposition.
