Mountain Catchment Areas for the Witzenberg Municipality

Mountain Catchment Areas for the Witzenberg Municipality

Identified ‘Critical Biodiversity Areas’(CBAs) and ‘Ecological Support Areas’ (ESAs) from the Western Cape Biodiversity Framework (Kirkwood et al., 2010), updated in 2014 (Pence) to more accurately reflect conditions relevant to land-use decision making. The Western Cape Biodiversity Framework (WCBF) provides an edge-matched, wall-to-wall coverage of all standard CBA categories to inform land-use decision making. Areas have either been formally assessed as part of a recognised Systematic Biodiversity Plan or only have ‘known’ CBA and ESA features indicated.

Wetlands, functional wetland types, wetland groupings and corresponding SA veg types for the priority area of the Witzenberg Municipality.

Integrated Vegetation Layer for the Witzenberg Municipality. Original extent of vegetation types mapped for the Fine-Scale Biodiversity Planning Domains: Saldanha Peninsula, North West Sandveld, Bokkeveld and the Upper Breede River Valley patched into the South African Vegetation Map and enhanced using other vegetation data layers. 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.

Witzenberg has been divided into two on the basis of where fine scale planning was and was not done. Please see CBA_and_ESA_Witzenberg_2.shp for the remainder of Witzenberg CBAs
