The site was identified as important in 2016 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
Corncrake Crex crex	LC	breeding	2011-2015	6-12 breeding pairs	C6
Black Tern Chlidonias niger	LC	breeding	2011-2015	75-92 breeding pairs	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2017) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Corncrake Crex crex	5	6	breeding pairs	100	favourable
Black Tern Chlidonias niger	60	75	breeding pairs	100	favourable

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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Unknown	low
