The Landmark Foundations' area of focus makes up 42000km of the Eastern and Western Cape. The Robertson corridor project in the Rooiberg Breede River Conservancy is a branch of the research area focusing on the corridor linking the Overberg and Riversonderend Mountains and the mountain ranges between De Doorns and Montagu. This area has been identified as an important conservation site as it forms a natural corridor for leopards and other wild species to link to one another.
