Threats to Nature's Contributions to People provided by terrestrial vertebrates across Europe

Abstract

Aim.Species and ecosystem processes offer essential benefits to people, known as Natures Contributions to People (NCP). However, we still lack a comprehensive understanding of NCP provided by terrestrial vertebrates on a large scale, and of the threats they face. To bridge this gap, we built a comprehensive dataset that documents the NCP provided by terrestrial vertebrate species in Europe, and analysed the conservation status and threats to NCP provider species. Location.Europe Methods.We synthesised existing literature on NCP associated with European terrestrial vertebrates, and leveraged ecological traits and trophic interactions from previously established datasets. We identified 15 NCP (10 regulating NCP and 5 non-material NCP), with 860 species providing at least one NCP (out of 1,168 vertebrate species considered in total). Then, we harnessed species distribution data and a novel European land system map to create species-mediated NCP maps across Europe at a 1km{superscript 2} resolution, including societal demand for each NCP. Results.We found that i) for each NCP, at least 25% of NCP provider species are assessed as threatened with extinction; ii) NCP multifunctionality is lowest in high-intensity land systems; and iii) direct exploitation and agricultural intensification are major threats to species-mediated NCP, impacting both non-material and regulating NCP provider species. Main conclusions.Protecting threatened NCP provider species, and reducing direct exploitation are key to maintain regulating and non-material NCP. Our results suggest that de-intensifying agricultural practices, through maintaining heterogeneous mosaic landscapes and promoting diversified practices, could increase NCP multifunctionality. Our work enables a comprehensive understanding of NCP provided by terrestrial vertebrates in Europe, their biogeography, and the threats they face, which can in turn inform spatial conservation planning to improve the conservation of both biodiversity and NCP.
