The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Cape Spurfowl Pternistis capensis	LC	resident	1998	present	A3
Cape Rockjumper Chaetops frenatus	NT	resident	1998	present	A1, A2, A3
Victorin's Warbler Cryptillas victorini	LC	resident	1998	present	A2, A3
Cape Bulbul Pycnonotus capensis	LC	resident	1998	present	A3
Cape Sugarbird Promerops cafer	LC	resident	1998	present	A2, A3
Orange-breasted Sunbird Anthobaphes violacea	LC	resident	1998	present	A2, A3
Protea Canary Crithagra leucoptera	NT	resident	1998	present	A1, A2, A3
Cape Siskin Crithagra totta	LC	resident	1998	present	A1, A2, A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
