ABSTRACT Contemporary conservation planning emphasizes target driven approaches for systematic identification of priority areas for biodiversity conservation. Budgetary constraints facing conservation agencies, particularly in developing countries, requires that the maintenance of existing reserves and the delineation of new reserves occurs in the most cost-effective manner possible, but little is known about whether the resources allocated to conservation areas reflects their conservation importance. The aim of this study was to quantify the conservation importance of every existing conservation area within the South African province of Mpumalanga and relate their importance to their current protection status. Using geographic information systems and associated conservation planning software, I assessed the spatial distribution of 336 key biodiversity features and calculated conservation importance based on an area’s contribution to feature targets. The province has 161 conservation areas including the Kruger National Park, categorized into 3 conservation area types based on legal protection status. Results indicate that while these areas contribute more to provincial biodiversity targets than non-conservation areas, a large proportion of biodiversity is found in informally protected areas such as conservancies and heritage sites. Conservation importance (determined through site irreplaceability) was 0.18, 0.04, and 0.10 for informal Type 3, semi-formal Type 2, and formally protected Type 1 conservation areas, respectively.
