The site was identified as internationally important for bird conservation in 2000 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Red-backed Shrike Lanius collurio	LC	breeding (1994)	51–55 breeding pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Common Crane Grus grus	1 / 1 (breeding pairs)	100	favourable
Montagu's Harrier Circus pygargus	1 / 2 (breeding pairs)	50	unfavourable

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation (management category)	% coverage of IBA
1985	Frøslev Mose	Fredet ved afgørelse, exl. Kirkeomgivelser (IV)	14
1992	Aabenraa Kommune	§3 beskyttet natur (alle søer, moser, vandløb, heder, enge mv) (IV)	17

Habitat	% of IBA	Habitat detail
