Optimum Colliery (12) commissioned an endorheic pan assessment in the mine area. During the assessment various pans were assessed and the status of the pans varied from severely degraded to a fairly good condition. The pans also have various conservation priorities, since some of the pans have very unique features (Strategic Environmental Focus, 2004). A wetland assessment was conducted at the Klipspruit Colliery (13) by Marneweck in 2002. It was determined that the wetlands on site are impacted on by various anthropogenic influences, including agriculture, mining activities in the past and the present mining activities. The wetlands were found to be moderately modified (Marneweck, 2002). An ecological assessment was conducted after the wetland assessment at Klipspruit Colliery (13) in 2003. The wetlands are indicated on the vegetation map of the mine area and the different wetland communities were identified. The wetlands are mostly moderately modified (de Frey, 2003). The status of wetlands assessed in the UORC therefore ranges from poor to excellent, however, it seems as if the majority of wetlands assessed are in a good condition. Only a very small percentage of the wetlands in the UORC were assessed and the status of the assessed wetlands may not be a true reflection of the general status of the wetlands in the catchment. The main impacts on the wetlands have been identified as Agriculture and associated activities, e.g. pesticides. Wetland Database for UORC - 68 -
