Figure 2: Current and future potential invasion hotspots of cultivated alien plants in Southern Africa . The maps represent current climatic conditions (a), moderate future climate change (SSP1) (b), and severe climate change (SSP5) by the end of the 21stcentury (2081-2100). We stacked the binary distribution maps of the 1,527 species and then identified high-risk regions defined as the top 10% of cells that were predicted to be suitable under current climatic conditions for the highest number of species (depicted in red); the same cut off value was then used for climate change scenarios.
