    Key achievements and progress towards National Biodiversity Assessment 2018
    (2017-06-21) van Deventer, Heidi; Smith-Adao, Lindie; van Niekerk, Lara; Foden, Wendy
    The National Biodiversity Assessment (NBA) is central to fulfilling SANBI’s mandate to monitor and report regularly on the status of the country’s biodiversity. It is a collaborative effort to synthesise the best available science on our biodiversity to inform policy and decision-making in a range of sectors, and contribute to national development priorities. The NBA focusses specifically on high-level indicators such as threat status and protection level for species and ecosystems. However, it also endeavours to capture the challenges and opportunities embedded in South Africa’s rich natural heritage by looking at biodiversity in the context of social and economic change and the relationship between people and their environment. SANBI does not have all the capacity required to undertake the NBA in-house, and draws substantially on contributions of time and other in-kind resources from a wide range of partners over the course of the 5-7 year cycle. This is important not only for completing the work, but also for the collective ownership of the NBA by the biodiversity science community in South Africa. The NBA is a multi-author and multi-stakeholder project. This overview presentation will highlight key achievements to date on the journey to NBA 2018 (to be published in 2019). It will look at significant advancements since NBA 2011 and touch on what is unlikely to be achievable for this NBA. While many presentations at the Biodiversity Planning Forum each year relate in some way to the NBA, this presentation will attempt to highlight those that are not necessarily covered in detail in other presentations.

    Refinement of spatial data on wetlands for the Mpumalanga Highveld region
    (SANBI, 2015-06-25)
    Much funding and specialist time has already been invested by WRC, CSIR, DWA and SANBI in the collaboration that generated the Atlas of Freshwater Ecosystem Protected Areas in South Africa: maps to support sustainable development of water resources, and its supporting technical and implementation manuals. The National Freshwater Ecosystem Protected Areas (NFEPA) project was a tremendous step forward in consolidating existing knowledge and generating new knowledge on the distribution, type and condition of freshwater ecosystems. However, experience in using the maps has shown that there is room to improve the underlying data (particularly the wetland layers) used to identify the Freshwater Ecosystem Priority Areas (FEPAs). This has implications for the confidence that can be attached to the information on ecosystem typing, condition and threat status generated by the project. The NFEPA project team acknowledged that, being of a national scale, the datasets would not be completely accurate at fine scale and that there was an ongoing need to refine these datasets over time, using more localized approaches. The Mpumalanga Highveld region of South Africa contains one of the highest concentrations of FEPAs in the country. The unique grassland and wetland association within the area is host to numerous threatened and conservation-worthy species and ecosystems. The area is also the source of several of the country’s major rivers, which collectively contribute 26% of South Africa’s natural mean annual runoff and 28% of its available water yield. Beneath the surface, the Mpumalanga Highveld straddles coalfields that are estimated to collectively contain 51% of national recoverable coal reserves. Under the WRC, a project was initiated to groundtruth and refine the current data layers of the extent, distribution, condition and type of wetlands ecosystems in the Mpumalanga Highveld coal belt. This talk will discuss tools and the methods used for the groundtruthing process. It will also showcase the improved data products and some of the statistics arising from this work.
