The Geography of Invasion Risk

Species ranges are one attribute that can be altered by climate change. The geographic limits of where you find a species and where you don’t are determined by the species’ biology, specifically in what climatic conditions can it survive. For some species, that’s warm and dry climates, for others it’s cool and wet, or one of many combinations of temperature and precipitation. Where a species’ range margin might contract and where it might expand in the future depend on how the suitable climate moves on a map for any given species. Knowing where a species can survive is the first step to managing invasion impacts.
