Abstract

We find a phase transition from no species to a highly diverse community, as the drought mortality and water table sharpness increases, but this is not true for water table depth. The species richness is decreasing with drought mortality and water table depth, but not with water table sharpness. Thin crown and intermediate values of photosyntetic efficiency (i. e. productivity) has the highest diversity.
