This Site in Lapland consists of six distinct areas of aapa mires and raised bogs divided by the Luiro River and other small streams. They are among the most important mires in Finland: the area is very biodiverse, containing the most extensive pristine rich birch fen area in the country and the two largest raised bogs in northern Finland. Nationally endangered plant species such as Lapland hook moss (Hamatocaulis lapponicus) and long seta hump moss (Meesia longiseta) are found. The area is also important for threatened bird species such as the nationally endangered Northern pintail (Anas acuta), garganey (Anas querquedula) and tufted duck (Aythya fuligula). Four priority wetland habitat types are listed under the European Union’s Habitats Directive; these provide carbon storage, flood control and water purification services. The main threats to the area are hunting, and drainage activities carried out on the margins of the Site.
