The site was identified as important in 2009 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
Spotted Crake Porzana porzana	LC	passage	2000-2009	3-5 individuals	C6
White Stork Ciconia ciconia	LC	non-breeding	2000-2009	1-10 individuals	C6
Common Kingfisher Alcedo atthis	LC	resident	2000-2009	2-3 breeding pairs	C6
Aquatic Warbler Acrocephalus paludicola	VU	passage	2000-2009	3-6 individuals	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

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

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Aquatic Warbler Acrocephalus paludicola	3	3	individuals	100	favourable
Sedge Warbler Acrocephalus schoenobaenus	1	2	females	100	favourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	poor (40-69%)	good (> 90%)	unfavourable
Wetlands (inland)	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
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Residential and commercial development	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 plan exists but the management planning process has begun	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
