Water quality overview and literature review of the ecology of the Olifants river
Expanded Title:The Olifants River in Mpumalanga is presently one of the most threatened river systems in South Africa (Ballance et al., 2001; De Villiers and Mkwelo, 2009; Van Vuren, 2009). Reports of unexplained fish and crocodile deaths within the catchment, including recently in the Kruger National Park (KNP) have been reported for several years and have received a media attention, including the establishment of the ‘Consortium for the Restoration of the Olifants Catchment’ initiative (Van Vuren, 2009; De Villiers and Mkwelo, 2009). Despite signs that water quality in the Olifants River has been deteriorating as a result of industrial, mining and agriculture activities, the trigger for episodic fish and crocodile deaths in the river system remains elusive (De Villiers and Mkwelo, 2009). This report is a summary of the status of the water quality data and is further a synthesis of the available aquatic ecology literature in the Olifants River.
