Forests disappear at an alarming rate leading to changes in species diversity and composition. It is therefore essential to study in which way modified forest conditions affect interactions among species and consequently ecosystem stability and function. Fundamental processes for ecosystem function are mutualistic and antagonistic interactions such as pollination, seed dispersal, seed predation and regeneration. This project aims at studying the regeneration potential of differently sized forest patches in the highly fragmented landscape of South Africa. Thereby, we will investigate the effects of forest type on biodiversity (insects, birds, small mammals, trees) and ecosystem processes (pollination, seed dispersal, seed predation and regeneration) in coastal scarp forests in KwaZulu-Natal, South Africa. These findings will help to develop sound management recommendations such as establishment of corridors and creation of forest patches and to foster the development of community-based natural management programmes improving peoples livelihood.
