2 Cape Flats: Part of World’s smallest Floral Kingdom  Cape Flats and Lowlands are part of the Cape Floral Kingdom and is smaller and more threatened than any of the other Kingdoms.  Cape Floral Region – one of 34 Global Biodiversity Hotspots and first non-tropical one to be recognised Cape Flats: Part of World’s smallest Floral Kingdom

3 Cape Flats NR: Centre of the Cape Lowlands  Cape Flats: human impacted, little remaining natural vegetation  Map shows Ecotone between two vegetation  The Cape Flats Nature Reserve, eighth most important site: due to size & floristics Dune Strandveld Dune Strandveld Sand Fynbos Sand Fynbos Ecotone Cape Flats NR: Centre of the Cape Lowlands

4  Broad-leafed shrubs  Calcareous sand substrate  50% transformed in Cape Town  Much disturbed (sand-mining)  False Bay/Blaauwberg  Meets the 10% IUCN conservation target Cape Flats Dune Strandveld Related to Sub-tropical Thicket of the east coast Cape Flats Dune Strandveld

5 PProtea, fine-leafed and restio plants HHigh species richness DDeep, leached acid sands >> 75% transformed in Cape Town HHighly disturbed (invasives, mining) OOne percent conserved OOne percent conserved Cape Flats world highest species extinction rates! Cape Flats Sand Fynbos

15 Natural Vegetation around the development

16 8 km radius and only two other reasonable habitats 8km8km Few and distant heighbours X ? Closest 2 sites lost or under threat and are Dune Thicket 9km9km Closest sites with Sandplain Fynbos all threatened ? ??X Cape Town 8 km radius and only two other reasonable habitats

17 Botanical Society: Assessment of core sites 1997  Cape Flats NR: rated 8 th most important  Had the 8 th most number of species  Most isolated and last viable site in the central Cape Flats area  Only one of two sites to have a transition between veg. types Other Consideration… Botanical Society: Assessment of core sites 1997

18 Events since Botanical Society site ratings  #1 Milnerton RC been developed – small part reserved  #3 Macassar – sand mining/human pressure  #4 Kenilworth RC under threat of still more housing development  #7 N1-N7 brushcut by Eskom due to fire risks  #8 Cape Flats NR: development ? Only Rondebosch Com. & Rondevlei safe ? Events since Botanical Society site ratings

19  UWC 150 ha Estate  Custodian of 42 ha of natural habitat heritage  34 ha vacant disturbed space to develop The BCB request: Our new building is shifted 80 m http://mapserver.uwc.ac.za/imf-aims50/imf.jsp?session=18868 Visit: A s m a l l s t e p t o t h e l e f t … The BCB request: Our new building is shifted 80 m
