The site was identified as important in 2004 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
Common Tern Sterna hirundo	LC	breeding	2001	250 breeding pairs	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2013) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Common Tern Sterna hirundo	260	9	breeding pairs	4	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%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

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	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
2004	Kalviu atkuriamasis sklypas	Atkuriamasis sklypas	97
2006	Kalvių karjeras	Special Protection Area (Birds Directive)	97

Habitat1	Habitat detail	% of IBA
Wetlands (inland)	Standing freshwater	95
Forest	Native coniferous woodland	3
Artificial/Terrestrial	Arable land	2

Land use	% of IBA
energy production and mining	100
