Site details
Site description: The park covers Gop³o lake and surroundings, as well as the Skulskie lakes (Skulskie, Skulska Wieœ, Czartowo) that are part of the Noteæ river system. Gop³o lake (25 km long) has flat, unforested shores with extensive beds of reed Phragmites. There are some islands (25 ha), covered mainly with reed. The surrounding area is covered mainly by wet meadows, fields and small forests.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: During autumn passage a total of 20,000 or more waterbirds stage regularly at the site, mainly wildfowl, and especially geese Anser. Breeding species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (one pair). A total of 198 species have been recorded, including 74 waterbirds.
Delineation rationale: 2004: site area has been reduced from 12,700 ha to 9885 ha.

Threats
Summary of threats to biodiversity at KBA: The drainage of adjoining land has resulted in a lower water-level in the lake. Agriculture has resulted in nutrient pollution of the lake, through fertilizer run-off from fields. Reed-harvesting is also a threat (`Other'). Fisheries, angling and sailing cause disturbance to birds, and hunting is a problem.
