Species richness in Europe

Notes: It is not possible to discriminate between data from the European and the Asian part of the Russian Federation. Macaronesia is not taken into account. An analysis by biogeographic region would be more relevant. However, lack of harmonised geo-referenced data on species distribution, particularly plants, does not yet allow such analysis. Despite their essential role in ecosystem functions, invertebrates and lower plants are not taken into account due to knowledge deficiency.
