Présentation
The seed ecology of the Cape Flats Sand Fynbos (CFSF) vegetation’s species in Blaauwberg Nature Reserve, in Western Cape South Africa, was investigated within the context of a broader restoration ecology project “Blaauwberg Ecological Restoration Project”1. Cape Flats Sand Fynbos (CFSF) vegetation is considered as a critically endangered vegetation type due to agricultural development, urban transformation, and degradation caused by invasive alien Acacia species. The City of Cape Town is clearing alien plants at Blaauwberg Nature Reserve (BBNR) in an attempt to restore this remaining CFSF fragment. These efforts are associated with challenges, since alien stands have depleted indigenous soil-stored seedbanks. The premise for this seed ecology study was that restoration of degraded CFSF is possible through applied management programmes based on the methodology and practice of active restoration. Active restoration is necessary in order to establish the major indigenous plant guilds and to revive areas that have been degraded due to the effects of the alien plants. Pre-germination treatments including smoke-derived compounds have been known to promote seed germination ; however, after a burn in Blaauwberg Nature Reserve, seeds sown in the field had low germination. One reason for the low germination of re-introduced indigenous species could be a lack of pre-germination treatments prior to sowing or drought thereof.
