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
White-winged Flufftail Sarothrura ayresi	CR	non-breeding	1998	30-50 individuals	A1, A4i
Southern Bald Ibis Geronticus calvus	NT	resident	-	present	A1

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 (2014) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Energy production and mining	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>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
