We explained vascular plant species richness patterns in a 286 km2
fragmented landscape
with a notable human influence. The objective of this study was two-fold: to test the relative
importance of landscape, topography and geodiversity measures, and to compare three
different landscape-type variables in species richness modeling. Moreover, we tested if
results differ when only native species are considered. We used generalized linear modeling
based variation partitioning and generalized additive models with different explanatory
variable sets. Landscape and topography explained the majority of the variation but the
relative importance of topography and geodiversity was higher in explaining native species
richness than in explaining total species richness. Differences between the three landscape
type variables were small and they provided complementary information. Finally, topography
and geodiversity often direct human action and can be ultimate causes behind both
landscape variability and species richness patterns.
