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.
