CBA 1: Natural landscapes: • Ecosystems and species fully intact and undisturbed • These are areas with high irreplaceability or low flexibility in terms of meeting biodiversity pattern targets. If the biodiversity features targeted in these areas are lost then targets will not be met. • These are landscape that are at or past their limits of acceptable change CBA 2: Near-natural landscapes: • Ecosystems and species largely intact and undisturbed. • Areas with intermediate irreplaceability or some flexibility in terms of area required to meet biodiversity targets. There are options for loss of some components of biodiversity in these landscapes without compromising our ability to achieve targets. • These are landscapes that are approaching but have not passed their limits of acceptable change. Ecological Support Areas (ESA): Functional landscapes: • Ecosystems moderately to significantly disturbed but still able to maintain basic functionality. • Individual species or other biodiversity indicators may be severely disturbed or reduced. • These are areas with low irreplaceability with respect to biodiversity pattern targets only. The presence of CBA 1 north of Aggeneys, and with CBA 2 in the vicinity (Figure 21), indicates that there are important biodiversity areas in that vicinity. An Ecological Support Area (ESA) forms a corridor south of Aggeneys (from Marsh et al. 2009). From this data it is suggested that the proposed photovoltaic power generation facility be located in an area which does not qualify for CBA 1 or CBA 2. 66
7.4 Fine Scale Biodiversity Fine scale biodiversity maps of the area were produced SKEP (2005). Figure 22. Map indicating biodiversity areas (Image provided by SRK Consulting) The biodiversity map (Figure 22) indicates that proposed development is located in the “Plains sandy hummocky” and “Plains sandy flat”, which has relatively low biodiversity, in relation to the “Plains rocky” and “Mountains”. This data indicates that, from an ecological and biodiversity perspective, the development will be located on the least sensitive areas on the property. 7.5 Zuurberg Important Biodiversity Areas These Biodiversity Areas are indicated in Figure 23. 67
