CAPE Lowlands Renosterveld – Ecological Processes (River Corridors). Riverine corridors along all perennial rivers. These are spatial components of ecological and evolutionary processes such as seed dispersal, pollinator movement along strips of riparian habitat. Other ecological and hydrological processes are dependent on the water course. All perennial rivers were identified. A 100 m buffer was mapped on each side of the river. The buffer was divided into sections, which were identified according to the land use - ‘natural vegetation’, ‘cultivated land’ or ‘urban area’.

These data represent aquatic sites identified as Critical Biodiversity Areas through the systematic assessment conducted by the C.A.P.E. Fine-Scale Biodiversity Planning (FSP) project. They include both the aquatic feature itself as well as the required buffer area surrounding the aquatic feature. Taken as a whole (aquatic plus terrestrial CBAs), these represent the sites required to meet biodiversity pattern targets and ecological process objectives. The loss of a single site would therefore compromise the meeting of targets and objectives. Thus it is recommended that the sites be managed in a manner compatible with biodiversity conservation, and ultimately remain in, or be restored to, a natural state. Ecological composition, structure, and function must be preserved.

The MBCP Aquatic Biodiversity Assessment was generated using MARXAN software in a Systematic Conservation Planning process. Subcatchments were use as planning units and modelled from 90m DEM with minimum size of 2500 ha. 157 Biodiversity and water production features, and targets were used in the analysis. The resulting ‘irreplaceability’ values and most efficient planning unit selection were categorized into biodiversity value classes.

Aquatic CBA and ESA for the NW province, with layer file.

This data shapefile represents random points created within subcatchments where fish species of conservation concern occur. The actual points are not accurate, but identify the important catchments and species only. Any activities within the subcatchment, not the position of the fish symbol, needs to be considered. Activities that could have a detrimental impact on fish populations on site, or downstream, must be avoided at all costs. The existence of fish support areas should also trigger appropriate studies to assess potential impacts. The data is primarily sourced from NFEPA, although supplemented with occurrence records from MTPA's freshwater ecosystems unit for fish of conservation concern. The NFEPA input data layer included the Fishsanc_All_Spp.shp shapefile. A metadata extract for this layer: " This shape file provides a list of all threatened and near-threatened fish species within fish sanctuaries. Fish species with an IUCN status of Critically Endangered or Endangered are identified in this layer. Expert opinion was also used to update the IUCN status for some fish species. Expert opinion status (based initially on IUCN status) is provided in this shapefile for each species .." Changes were made to the attribute table and additional random points within the subcatchment were added. The final product is a point shapefile indicating the presence of a fish, or many fish, of conservation concern with a subcatchment. The attribute data includes a count of species of conservation concern within the subcatchment as well as a list of species and their status categories (from NFEPA and MTPA river scientists).

SKEP Expert Maps (Amphibians, Birds, Fish, Insect, Invertebrates, Mammals, Plants, Reptiles). The SKEP expert maps (Amphibians, Birds, Fish, Insect, Invertebrates, Mammals, Plants, Reptiles) were mapped by experts on 1:250 000 topocadastral maps and digitized by Benis Egoh (IPC).
