Slide 22: Tier 3 CCS3 - Bioclimatic & Dispersal Time Slice modelling
These maps show the movement of these species per decadal time slice and illustrate the outcomes for species using null, full and partial assumptions of migration. As can be seen, assuming no migration, there is a good likelihood that the threatened species may face extinction within 50 years, given the Hadley GCM's predicted changes in climate. Assuming partial movement, the area in which the species still exists by 2050 is considerably reduced, and limited to several mountain refugia that are close to extant areas. Even assuming full movement at the maximum rate available to each species, the area of survival is considerably reduced, making it clear that climate change is likely to have a significant impact on the proteas of this region.
