Fig. 4. Mapping critical connectivity areas (CCAs) globally.(A) Current protection status of intact CCAs
and modified CCAs. Pie charts indicate the proportion of each CCA type in each continent. (B) Potential
future protection and threat status of CCAs. Potential future protection occurs where currently unprotected
CCAs overlap with areas prioritized for expanded conservation under the Global Safety Net (GSN). Future
threats were examined where CCAs fall outside of the GSN (i.e., remain unprotected) and overlap with areas
predicted to be suitable for future agricultural (Ag) expansion ( 27 ).
