An assessment of the freshwater natural capital in KwaZulu-Natal for conservation planning

Abstract

Freshwater conservation planning, while lagging behind terrestrial conservation planning, is beginning to be implemented in a complementary manner to the latter. Ezemvelo KZN Wildlife is currently preparing an aquatic conservation plan for the freshwater systems of KwaZulu-Natal. The development of a freshwater conservation plan requires an initial understanding of the broad characteristics of the resource and associated biodiversity. Within KwaZulu-Natal, which is water-rich relative to the remaining provinces in South Africa, there are approximately 585 000 ha of mapped freshwater wetlands, 17% of which fall within protected areas. At the 1:500 000 scale, there are in excess of 18 400 km of perennial and ephemeral rivers mapped, and just over 1 000 km (5.6%) of these fall within existing formal protected areas. The river systems feed into 79 estuaries covering a mapped area of over 30 600 ha, of which 41% amounting to almost 12 400 ha are found largely within protected areas, although this does not reflect the actual number protected.
