The site was identified as important in 2010 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
Great Snipe Gallinago media	NT	breeding	2005-2009	4-10 males	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2009) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Great Snipe Gallinago media	10	10	males	100	favourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	poor (40-69%)	poor (40-69%)	very unfavourable
Forest	poor (40-69%)	moderate (70-90%)	very unfavourable
Artificial/Terrestrial	very poor (< 40%)	very poor (< 40%)	very unfavourable

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
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Energy production and mining	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
No known threats	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	No management planning has taken place	Some limited conservation initiatives are in place	low
