This repository contains extensive data for the European Alps: - Observations of ~3,500 plant species - Climate (1-km), soil (100-m) and land cover predictors (1km); current and future scenarios (28 CMIP6-GCMs, 2 land cover change and 3 dispersal scenarios i.e., unlimited, no and realistic vegetation dispersal) - Flora migration rates (categorical) and ecological preferences (continuous indicator values) - Regional maps of barriers to migration and water bodies at 100-m resolution - Sampling effort, distance to roads and cities predictors at 100-m resolution - Present and future abundances over the study region at 1-km resolution (~2,000 species) - Present and future multifaceted and uniqueness of the European Alps' Flora at 1-km resolution - Present and future conservation recommendations at 1-km resolution (26 current and future strategies) - Phylogenetic data and functional traits of ~2,000 plants (raw data and classification trees) - All scripts, data and plots used for the analyses, including a singularity container (mini-linux) to run them
