WCDMA01 Habitat and Ecosystem Status 2010 (WC_MatzPD_Habitats&Ecostatus.shp )
Base habitat map of terrestrial habitats created from a combination of existing finescale vegetation maps with interpolation and refinement of the national vegetation map based on landscape characteristics; With Ecosystem Staus and Protection Levels As calculated by Skowno et al 2010. Clipped to the core planning domain consisting of West Coast District Management Area and northern Matzikama LM.

Methodology:
Habitat Mapping:The vegetation of the planning domain was totally remapped at a scale of between 5000 and 50 000 from SPOT 5 satellite and Google Earth imagery, and landscape models were incorporated into the differentiation of vegetation units (Figure 5).
There were several reasons why remapping was necessary:
The existing Rutherford & Muncia, 2006 vegetation map was mapped at a scale of 1:250 000. Whilst this is satisfactory for national-level assessments the application of this product to on-the-ground decision making means that the boundary error in this map made it totally unsuitable for the desired purpose of this product (Figure 6); The availability of high-resolution colour satellite imagery has facilitated the better mapping of vegetation; Whilst for the most part the vegetation concepts in Rutherford & Mucina (2006) are sound there have been some changes in interpretation of the regional vegetation, particularly in the Sandveld, that required the remapping of these areas; The existing fine-scale vegetation map for the Namaqualand Sand Fynbos needed to be incorporated into an updated product; Remapping the vegetation allowed for the incorporation of new expert knowledge on the distribution of recognised vegetation types; the addition of new vegetation types; as well as the identification and mapping vegetation sub-types; and The vegetation map is the primary biodiversity information layer informing the CBA map therefore it is important to ensure that the mapped product matches conditions on-the-ground. Ecosystem status calculations are based on a union between the vegetation, transformation and protected areas layers for the “Core planning Domain” which cover the WCDMA and the northern part of the Matzikama LM (see chapter 3). A pivot table was used in Excel to calculate per vegetation type summary statistics of transformation, degradation and protection. Separate ecosystem status calculations were performed using transformation only and transformation and degradation together.
