Addressing risks to biodiversity arising from a changing climate: The need for ecosystem restoration in the Tana River Basin, Kenya

S4 Fig. Locations of projected refugia for plants with 2˚C and 4.5˚C warming. A refugium is identified in a grid cell only if at least 11 of the 21 GCMs agree in projecting its existence. (TIF) S5 Fig. Locations of projected refugia for reptiles with 2˚C and 4.5˚C warming. A refugium is identified in a grid cell only if at least 11 of the 21 GCMs agree in projecting its existence. (TIF) S6 Fig. Locations of projected refugia for all five taxa with 2˚C and 4.5˚C warming. A refu- gium is identified in a grid cell only if at least 11 of the 21 GCMs agree in projecting its exis- tence. (TIF) S7 Fig. GCM agreement that protected areas contain refugia with different levels of warm- ing. These results are based on a no dispersal scenario. The five classes of species are amphibi- ans, birds, mammals, plants and reptiles. (TIF) S8 Fig. Key features of Kenya’s National Spatial Plan affecting the Tana River Basin. Key features of the National Spatial Plan (Government of Kenya, 2017) within the Tana River Basin boundary were digitised using GIS. (TIF) S9 Fig. Importance of facilitating dispersal for birds with 2˚C warming. The first column (left) shows species richness remaining when species are not able to shift their ranges, the cen- tre column shows the scenario where species are able to disperse, and the final column (right) shows the difference between the first two. The top panels show the 10th percentile, the middle shows the 50th percentile and the bottom panel shows the 90th percentile. (TIF)

S10 Fig. Importance of facilitating dispersal for birds with 4.5˚C warming. The first column (left) shows species richness remaining when species are not able to shift their ranges, the cen- tre column shows the scenario where species are able to disperse, and the final column (right) shows the difference between the first two. The top panels show the 10th percentile, the middle shows the 50th percentile and the bottom panel shows the 90th percentile. (TIF) S11 Fig. Importance of facilitating dispersal for mammals with 2˚C warming. The first col- umn (left) shows species richness remaining when species are not able to shift their ranges, the centre column shows the scenario where species are able to disperse, and the final column (right) shows the difference between the first two. The top panels show the 10th percentile, the middle shows the 50th percentile and the bottom panel shows the 90th percentile. (TIF) S12 Fig. Importance of facilitating dispersal for mammals with 4.5˚C warming. The first column (left) shows species richness remaining when species are not able to shift their ranges, the centre column shows the scenario where species are able to disperse, and the final column (right) shows the difference between the first two. The top panels show the 10th percentile, the middle shows the 50th percentile and the bottom panel shows the 90th percentile.
