| Abstract | Aim: Biodiversity is increasingly threatened by human impacts. While abiotic conditions are well known to shape species rich-ness, the role of human activities remains less clear. We examined how abiotic and human factors influence terrestrial and limnicspecies richness in a densely populated region with a long land-use history.Location: Germany.Time Period: 1900–2023 (varies by taxonomic group).Major Taxa Studied: Mammals, breeding birds, fishes, amphibians, reptiles, butterflies, dragonflies, fungi, vascular plants.Methods: Species richness data were aggregated in 11 × 11 km grid cells and related to abiotic (climate, soil) and human drivers(land use, protection status). We applied a two-step approach: (1) Boosted Regression Trees (BRTs) to select relevant predictorvariables and (2) Generalised Additive Models (GAMs) to test their effects, accounting for spatial autocorrelation.Results: Land-use and climate were similarly important for species richness (26% vs. 21% in BRTs), while protection status andsoil contributed less (8% and 9%). GAMs showed positive effects of temperature across many groups. Among land-use factors,human footprint, urban open spaces and water bodies consistently enhanced richness. Protected areas were positively related torichness, whereas soil variables had mixed effects.Main Conclusions: In Germany, species richness peaks not only in semi-natural, protected areas but also along water bodiesand within settlement open spaces. These results suggest that conservation strategies should integrate both traditional protectedareas and human-modified habitats that sustain high biodiversity. |
