Bird Wetlands of Siikajoki. 02/02/04; Oulu; 2,691 ha; 64°52'N 024°48'E. Natura 2000 SPA, SCI, WHCP. The four main adjacent shore areas around Siikajoki consisting of capes, a river estuary, mires and shoals, which together form a unique wetland unit for breeding and migrating bird fauna. At the centre of the site is the Merikylänlahti sea bay characterized by coastal meadows in the process of turning into a gloe lake formation. In general the flora of the site contains two very special groups, the endemic species of the Gulf of Bothnia and the so-called Primula nutans (Siberian primrose) group of arctic species in isolation from the main distribution areas of the Arctic Ocean. The importance of the area is exceptional in migration periods. Increased recreation and extension of holiday dwelling constructions, as well as intensive hunting of waterfowl, are causing disturbance. Furthermore the planned road connection to Hailuoto Island threatens the northeastern part of the Ramsar site. Ramsar site no. 1508. Most recent RIS information: 2005.
