Fig. 2. Three-dimensional maps of the Cape Peninsula showing eight hypothetical scenarios of available land for baboons. We combined these scenarios with two baboon density estimates to explore the total number of baboons that the Cape Peninsula could support. In both A and B, the total areas of available land decrease progressively from 1 to 4 in accordance with increasing access restrictions. A includes all land in the Cape Peninsula, while B includes only land immediately adjacent to troop home ranges and accessible within a one-day journey. In all scenarios baboons are denied access to urban habitat. In both A and B the details of Scenarios 1 to 4 are as follows: In Scenario 1 baboons are allowed unlimited access to natural habitat, invasive alien vegetation, and agricultural habitat. Scenario 2 is based on Scenario 1 but considers that all invasive alien vegetation and the Tokai plantation have been restored to natural habitat. Scenario 3 is based on Scenario 2 but denies baboons access to remaining agricultural habitat (vineyard, ostrich farm). Scenario 4 is based on Scenario 3 but includes only natural habitat ≤600 m (see methods for rationale).
