Lake of Seven Islands Nature Reserve (Rezerwat pyzyrody "Jezioro Siedmiu Wysp"). 03/01/84; Warminsko-Mazurskie; 1,618 ha; 54°18'N 021°35'E. Added to the Montreux Record, 4 July 1990. Nature Reserve, Natura 2000, BirdLife IBA. The site, located on the border with the Kaliningrad region of Russia, includes a freshwater lake colonized by submerged vegetation and overgrown by reedbeds, associated marshland, meadows, woodland and moraine islands. An important inland staging site for migratory waterbirds, including geese and ducks, the site supports several species of breeding birds and rare mammals. Two northern tree species reach the southern limit of their distribution here. Human activities include forestry, as well as intensive agriculture in the surrounding areas. Threats to the site include urban and domestic effluent, nutrient-rich agricultural inflow, and vegetation encroachment into the marsh. Subject of a Ramsar Advisory Mission in 1989. Significantly extended in 2007. Removed from Montreux Record, 5 November 2007. Ramsar site no. 285. Most recent RIS information: 2007.
