Abstract

Hakea sericea is an aggressive woody invader of fynbos communities. Clearing operations aimed at the control of this weed are conducted in mountain catchment areas. This paper describes an experiment to test the effects of season of seed release in burnt and unburnt fynbos. No significant differences between seasons or between burnt and unburnt veld were detected, but this is ascribed to unusually heavy predation on the small plots. Seeds germinated in winter and differences in reproductive success following control operations in large areas should be similar to patterns observed for indigenous serotinous Proteaceae after fire. Although more data from actual control operations are necessary, it seems that reliance on a fairly intense fire to kill seedlings is a better control strategy than manipulation of seedling survival according to season of felling.
