Mountain Catchment Areas for the Witzenberg Municipality

The NBA2018 cumulative marine pressure dataset combines 31 marine pressure datasets (e.g. the location of 20 fishery activities, petroleum activities etc). Pressure data is a key input into assessing ecosystem condition.

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)

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.
