Wolkberg Forest Belt


IBA Justification

The site was identified as internationally important for bird conservation in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:
Species Red List Season (year/s of estimate) Size IBA criteria
Striped Flufftail Sarothrura affinis LC resident (1998) present A3

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2014) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2014 very poor high low
Whole site assessed? State assessed by Accuracy of information
yes habitat medium

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Grassland poor (40–69%) poor (40–69%) very poor

Natural system modifications happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Agricultural expansion and intensification happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Residential and commercial development happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Energy production and mining likely in long term (>4 years) some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Some of area covered (10–49%) A management plan exists, but it is out of date or not compre­hensive Some limited conservation initiatives are in place low
