Data on the species distributions of twelve higher taxa of animals and plants are used to explore the extent to which hotspots of species richness tend to coincide across Europe on an equal area grid (squares of approximately 152,000 km2). One or two of the hotspots of many of the numerous possible pairwise combinations of higher taxa are congruent, but for no pair of higher taxa do three hotspots coincide. Contrasted with a simple null model, there is a greater incidence of positive associations of hotspots between higher taxa than expected, and more areas contain several hotspots than expected The overall numbers of species of all higher taxa, found within the hotspots of individual higher taxa, are very consistent 50-56% of all species occurred in the richest hotspots, and 60-70% in the top three hotspots.
