Development of a tool for assessment of the environmental condition of wetlands using macrophytes
Expanded Title:This is the last report of 11 reports emanating from Phase 2 of the WRC Wetland Health and Importance (WHI) research programme. In addition to biotic indices using macrophytes and aquatic invertebrates, a method for the assessment of temporary wetlands during dry conditions and a method for the assessment of the cumulative impacts of human activities at the landscape and catchment levels on wetlands was developed. The socio-economic aspects of wetlands ecosystem services were investigated and case studies presented. This research focussed on the winter-rainfall area of the Cape coastal lowlands and on macroscopic plants found within the ecosystems of inland wetlands. In addition to a synthesis of existing local and international information on the responses of wetland-affiliated plants to changes in ecological drivers, the report presents a protocol appropriate for the development of phyto-assessment indices for palustrine wetlands in South Africa . The aims of the WHI programme were to develop tools to assess the ecological condition as well as the socio-economic importance of wetlands. In view of the widespread use of wetlands, to develop a tool to assess the loss of wetland functions resulting from development and finally, to implement a communication programme. A number of projects, each led by a specialist, were appointed to address the specific aspects of the research. Three separate biotic indices were developed. These involved the use of macrophytes, aquatic invertebrates and a method for the assessment of temporary wetlands during dry conditions. A method was developed for the assessment of the cumulative impacts of human activities at the landscape and catchment levels on wetlands. This involves the measurement of impacts both within the wetlands as well as those remote from them. The socio-economic aspects of wetlands have been divided into four topics, each of which has been written up separately. The first of these is the current understanding and practice of the valuation of wetland ecosystem services. The second presents case studies to illustrate the range of uses to which wetlands are put. The third provides a tool for the assessment of the livelihood value of wetlands and the fourth a protocol for the quantification and valuation of wetland ecosystem services. In addition, the sustainability of and the ecosystem services realised from wetlands in the Kamiesberg uplands that have been used consistently for several generations have been assessed and improved management suggested.
