The site was identified as internationally important for bird conservation in 2007 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 List	Season (year/s of estimate)	Size	IBA criteria
Smew Mergellus albellus	LC	passage (2006)	10–30 birds	C6
Common Crane Grus grus	LC	breeding (2006)	7 pairs	C6
Arctic Loon Gavia arctica	LC	breeding (2005)	3–5 pairs	C6
Eurasian Bittern Botaurus stellaris	LC	breeding (2006–2007)	2–4 males	C6
Common Tern Sterna hirundo	LC	breeding (2005)	29–47 pairs	C6
Tawny Owl Strix aluco	LC	breeding (2006)	15–20 pairs	C6
Osprey Pandion haliaetus	LC	breeding (2005)	5 pairs	C6
European Honey-buzzard Pernis apivorus	LC	breeding (2006)	3–6 pairs	C6
Western Marsh-harrier Circus aeruginosus	LC	breeding (2006)	2–4 pairs	C6
White-tailed Sea-eagle Haliaeetus albicilla	LC	passage (2006)	5–20 birds	A1, C1, C6
Black Woodpecker Dryocopus martius	LC	breeding (2005)	14–18 pairs	C6
Red-backed Shrike Lanius collurio	LC	breeding (2006)	10–15 pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Arctic Loon Gavia arctica	5 / 15 (pairs)	34	very poor
Osprey Pandion haliaetus	5 / 10 (pairs)	50	poor
White-tailed Sea-eagle Haliaeetus albicilla	1 / 1 (pairs)	100	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Agricultural expansion and intensification	likely in long term (>4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	A management plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
2000	Solgens centrala övärld	Naturreservat (IV)	9
2011	Solgens norra övärld	Naturreservat (IV)	11
2011	Solgens södra övärld	Naturreservat (IV)	4
