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
Wattled Crane Bugeranus carunculatus	VU	resident (-)	present	A1
Blue Crane Anthropoides paradiseus	VU	resident (-)	present	A1
Knysna Turaco Tauraco corythaix	LC	resident (1998)	present	A2, A3
Forest Buzzard Buteo trizonatus	NT	resident (1998)	present	A3
Grey Cuckooshrike Ceblepyris caesius	LC	resident (1998)	present	A3
Olive Bushshrike Chlorophoneus olivaceus	LC	resident (1998)	present	A3
Yellow-throated Woodland-warbler Phylloscopus ruficapilla	LC	resident (1998)	present	A3
Bush Blackcap Sylvia nigricapillus	VU	resident (1998)	present	A1, A2, A3
Orange Ground-thrush Geokichla gurneyi	LC	resident (1998)	present	A3
White-starred Robin Pogonocichla stellata	LC	resident (1998)	present	A3
Chorister Robin-chat Cossypha dichroa	LC	resident (1998)	present	A2, A3
Buff-streaked Chat Campicoloides bifasciatus	LC	resident (1998)	present	A1, A3
Gurney's Sugarbird Promerops gurneyi	NT	resident (1998)	present	A3
Swee Waxbill Coccopygia melanotis	LC	resident (1998)	present	A3
Forest Canary Crithagra scotops	LC	resident (1998)	present	A2, A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2006) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Wattled Crane Bugeranus carunculatus	29 / 15 (adults)	100	good
Blue Crane Anthropoides paradiseus	12 / 15 (adults)	80	moderate

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70–90%)	moderate (70–90%)	poor
Forest	moderate (70–90%)	moderate (70–90%)	poor
Grassland	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Natural system modifications	likely in short term (<4 years)	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	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	high

Habitat	% of IBA	Habitat detail
Forest	56
Shrubland	30
Wetlands (inland)	13
Grassland	-

Land use	% of IBA
nature conservation and research	100
