WCBF2014 Critical Biodiversity Areas’(CBAs) and ‘Ecological Support Areas’ (ESAs) in Matzikama (CBA_and_ESA_terrestrial_Matzikama.shp)
Identified ‘Critical Biodiversity Areas’(CBAs) and ‘Ecological Support Areas’ (ESAs) from the Western Cape Biodiversity Framework (Kirkwood et al., 2010), updated in 2014 (Pence) to more accurately reflect conditions relevant to land-use decision making. The Western Cape Biodiversity Framework (WCBF) provides an edge-matched, wall-to-wall coverage of all standard CBA categories to inform land-use decision making. Areas have either been formally assessed as part of a recognised Systematic Biodiversity Plan or only have ‘known’ CBA and ESA features indicated.
Matzikama Municipality has been divided into two on the basis of where fine scale planning was and was not done. Please see CBA_and_ESA_DMA01.shp for the remainder of Matzikama CBAs and ESAs

- Purpose
-
All Critical Biodiversity Area (CBA) data for the Western Cape were updated to more accurately reflect: where CBAs were intentionally identified within agricultural fields, where CBAs have been lost to agricultural expansion (between 2007 and 2011), where CBAs are potentially rehabilitating from agricultural land-use, and where CBAs have now been secured into the Protected Area Network.

Step 1: CBA data updated with DAFF field data
? Best available CBA layers were sourced from either the Western Cape Biodiversity Framework 2010 municipal datasets or the Updated Fine-Scale Biodiversity Planning project municipal datasets held by CapeNature.
? CBA records were isolated from the broader set of CBAs plus ESAs, ONAs, No Natural Areas and PAs (from the “Category” field in the original attribute tables).
? A “New_CAT” (New Category) field was added (type = text or string).
? The new CBA-only data layers were unioned (ArcMap 10.2.1) first with the 2007 DAFF field dataset and then the 2013 DAFF field dataset1 (wc_fields_20070621_I_utm34wgs.shp and WcFb_2011Spot5_2013_UTM34S.shp, respectively).
? Following the unions, all non-CBA records where first deleted and then a series of queries were used to identify places (i.e., records) where: (1) CBAs do not overlap with agricultural fields, (2) CBAs overlap with fields in 2007 only, (3) CBAs overlap with fields in 2011 only, and (4) CBAs overlap with fields in both 2007 and 2011.
? The “New_CAT” field was populated to reflect these combinations of attributes:
o CBA only
o CBA and field in 2007
o CBA and field in 2011
o CBA and field in both 2007 and 2011
? Later these categories became:
o CBA
o CBA (potentially rehabilitating agric land)
o CBA lost to agric landuse
o CBA (known agric landuse)
? Renamed “HabCon” field “HabCon_org”
? recalculated area
Step 2: ESAs then merged with CBAs - (Kirkwood et al., 2010), updated in 2014 (Pence) to more accurately reflect conditions relevant to land-use decision making.
