Abstract Renosterveld is a characteristic and once dominant vegetation type of the CFR and strongly threatened by conversion to agricultural areas. Both destruction and conversion lead to an increased fragmentation of the habitats, which is an additional threat for the vegetation and species still growing in the remnants. Therefore, first attempts were made to restore the respective communities on former arable land or on pastures. However, the information is still lacking on which species of the respective communities are able to re-establish, and on which factors such as soil conditions or disturbance regimes the re-establishment is dependent upon. In addition, very few studies on the germination ecology of renosterveld exist. This study intends to test factors contributing to successful re-establishment of indigenous species in a restoration experiment at the Tygerberg Nature Reserve by applying alternative restoration practices.
