  • This layer represents is an integration of the fine-scale vegetation map of the Saldanha Peninsula, North West Sandveld, Bokkeveld and Upper Breede River Valley mapping domain in the Western Cape; fine-scale mapped wetland vegetation types for Saldanha and Sandveld; the South African Vegetation map (NSBA 2004 updated to 2006 where name and spatial changes were found), Nieuwoudtville Conservation Farming Project Vegetation Map and extracts from Barry Low’s Dune Ecosystem Layer. Fine-scale vegetation categories were based on the South African vegetation types of Mucina & Rutherford (2006), but it was necessary to describe a several new, previously unrecognised vegetation types in the FineScale Planning Domains. Certain vegetation boundaries were substantially redrawn from those presented in Mucina & Rutherford (2006)

  • SKEP Expert Maps (Amphibians, Birds, Fish, Insect, Invertebrates, Mammals, Plants, Reptiles)

  • Projected change in maize(mz) productivity using the mechanistic crop growth model, DSSAT(ds) Band 1 - 11th percentile projected percent change in yield for enhanced CO2 response simulations Band 2 - 50th percentile projected percent change in yield for enhanced CO2 response simulations Band 3 - 88th percentile projected percent change in yield for enhanced CO2 response simulations Band 4 - 11th percentile projected percent change in yield for unenhanced CO2 response simulations Band 5 - 50th percentile projected percent change in yield for unenhanced CO2 response simulations

  • GCBC Ecological Processes – Vegetation Type Transition Areas

  • Areas invaded by alien plants in Gouritz. Area described by J Vlok and digitised by T Wolf. The broad distribution of invasive alien plants was mapped using a Landsat image in the background.

  • Fish sanctuaries are sub-quaternary catchments that are essential for protecting threatened and near-threatened freshwater fish populations that are indigenous to South Africa. Fish sanctuaries were identified at the scale of sub-quaternary catchments. The SAIAB/Albany fish data were used to guide the choices. This shapefile provides a summary of what the sub-quaternary catchment status is in terms of being selected as a FEPA, Fish Support Area, Fish Relocation & Translocation Area, Fish Rehabilitation Area and Migration Corridors for threatenedand near-threatened fish indigenous to South Africa.

  • Gouritz Initiative - Processes – Koppies. Sensitive koppies in the Gouritz Initiative, which support highly localized geophytes and small succulent plants, which are often threatened.

  • Renosterveld Priorities Clusters for the Cape Agulhas, De Hoop Management Area, Overstrand, Drakenstein Municipality, Swartland, Swellendam and Theewaterskloof Municipalities. Layer designating renosterveld conservation priority clusters and the area surrounding the natural vegetation up to 500m (a 500m buffer). The patches of remaining lowland habitat within priority clusters were identified by the Cape Lowlands Renosterveld Project as critical for conserving biodiversity pattern and ecological processes of lowland renosterveld.
