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:

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
Grassland	good (> 90%)	good (> 90%)	favourable
Forest	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	slow but significant deterioration	high
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Natural system modifications	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	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
Human intrusions and disturbance	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
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
