- ItemMaking CBA Maps: Considering previous biodiversity plans in CBA Maps(2017-06-21) Desmet, Philip; Hawley-McMaster, Greer; Berliner, Derek; King, ThomasThis presentation discusses the conundrum of incorporating previous spatial biodiversity plans into updated maps of Critical Biodiversity Areas (CBA Maps). The issue is that when updating CBA Maps is it acceptable/justifiable to discard all previous biodiversity plans to create a novel CBA Map OR must existing biodiversity plans take precedence unless there is good reason not to include a site? The protocol here is important for planning where there have been several biodiversity plans before. We discuss the problem and provide some working rules to solve the problem based on our experiences with the recent update of the Eastern Cape Biodiversity Conservation Plan. Clear guidelines for resolving this issue need to be incorporated into the technical guidelines for developing CBA Maps.

- ItemReviewing a systematic biodiversity conservation plan: Eastern Cape(2017-06-21) Hawley-McMaster, Greer; Desmet, Philip; Berliner, DerekThe draft Eastern Cape Biodiversity Conservation Plan (ECBCP2017) is about to be released for public review prior to finalisation and gazetting. The ECBCP2017 is a complete update of the 2007 plan that has benefited from many new spatial datasets. All estuaries, including micro-estuaries, and rivers (valley bottom wetland model from Nacelle Collins) are mapped as polygons. The NFEPA river condition and fish feature data has been updated with the Department of Water and Sanitation Present Ecological State/Ecological Importance and Sensitivity dataset. A new wetland layer comprising expertmapped polygons and National Geo-spatial Information topo-map data, was developed. In the terrestrial environment, the land cover has been significantly augmented with historic field data (SANBI and Richard Lechmere-Oertel), and mapped gullies from the Agricultural Research Council. Department of Agriculture, Forestry and Fisheries’ Forest Inventory polygons have totally replaced forest patches in the VEGMAP 2012. A new southern African biome climate-change response model (Guo, SANBI) and bush-encroachment mapping (Skowno, PhD dissertation) were included. The terrestrial MARXAN analysis used “intuitive” planning units based on land cover and hydrological catchments that better relate to observable discontinuities on the ground. The ECBCP2017 used improved biodiversity datasets; however, some data gaps remain with respect to threatened/rare species observations, modelled distributions and geographic areas. The expert mapping of important biodiversity features is still the most important biodiversity informant in the plan. The 2007 plan grappled with lack of data. The current plan grappled with the enormity of datasets in particular collating duplicate data and establishing/improving data accuracy. The map of Protected Areas and Conservation Areas has proved especially challenging in this regard. There are 31 other province-specific “spatial biodiversity plans” that needed to be considered in the current plan. The ECBCP2017 is part of a larger project to develop the Eastern Cape Biodiversity Strategy and Action Plan (ECBSAP). As such, the outputs from the spatial biodiversity plan are a key informant of the ECBSAP2017.
