The identified systems are not only described in terms of their plant species composition, but also evaluated in terms of the potential habitat for red data plant species. Red data plant species for the area were obtained from the SANBI data bases, with updated threatened status, (Raimondo et al. 2009). These lists were then evaluated in terms of habitat available on the site, and also in terms of the present development and presence of man in the area. Alien invasive species, according to the Conservation of Agricultural Resources Act (Act No.43 of 1983) as listed in Henderson (2001), are indicated. Medicinal plants are indicated according to the PRECIS list of SANBI, and is obtained from Smit (2007). The field observations were supplemented by literature studies from the area (Coetzee et al. 1994, 1995). 6.1.2 Plant Conservation Priority The following conservation priority categories were used for each site: High: Ecologically sensitive and valuable land with high species richness and/or sensitive ecosystems or red data species that should be conserved and no developed allowed. Medium-high: Land where sections are disturbed but which is in general ecologically sensitive to development/disturbances. Medium: Medium-low: Low: Land on which low impact development with limited impact on the vegetation / ecosystem could be considered for development. It is recommended that certain portions of the natural vegetation be maintained as open space. Land of which small sections could be considered to conserve but where the area in general has little conservation value. Land that has little conservation value and that could be considered for developed with little to no impact on the vegetation. SATO Aggeneys July 2011 32
6.1.3 Sensitivity Only High and Low sensitivity must be indicated. No development should be allowed on High sensitive areas. In terms of sensitivity the following criteria applies: High: High and Medium-High conservation priority categories mentioned above are considered to have a High sensitivity and development should not be supported. Low: Medium, Medium-Low and Low conservation priority categories mentioned above are considered to have a Low sensitivity and development may be supported. Portions of vegetation with a Medium conservation priority should be conserved. Plant species recorded in each plant community with an indication of the status of the species by using the following symbols: A = Alien woody species D = Dominant d = subdominant G = Garden or Garden Escape M = Medicinal plant species P = Protected trees species p = provincially protected species RD = Red data listed plant W = weed 6.2. Mammals The site visit was conducted on 27-28 June 2011. During this visit the observed and derived presence of mammals associated with the recognized habitat types of the study site, were recorded. This was done with due regard to the well recorded global distributions of Southern African mammals, coupled to the qualitative and quantitative nature of recognized habitats.
