We assessed the relative importance of climate and topography in explaining plant species richness, endemic richness and endemicity (i.e. percentage of endemics) using 890 vegetation plots, which cover the complete high-elevation island of La Palma (Canary Islands). Interestingly, evolutionary processes and human influences (both topography-related) seem to drive endemic richness. However, climate is more important for endemicity, leading to incongruent spatial patterns of diversity.
