Climate change may affect biodiversity to a large extent. Its effects have already caused shifts in species distributions and even species extinctions. Since especially high latitude regions are expected to be affected, this publication assesses the impact of future climate change on the biodiversity in the Barents Region (northern parts of Norway, Sweden and Finland, and Northwest Russia). It reports on the impact of climate change on a large range of species, including amphibians, butterflies, birds, mammals, moths, plants, slugs, snails, and reptiles, of which a few were studied more in depth. It further identifies future hotspots of species diversity and gives recommendations on species that should be prioritized for conservation and on areas that should be included in the network of protected areas in future. Lastly, it provides guidance on which aspects require further study.
