Overview
Tysjöarna is composed of two lime lakes and marl fields surrounded by calcareous fens, open and wooded fens and wetland forest. The calcareous fens hold a rich and typical flora, with populations of Schoenus ferrugineus, Carex jemtlandica, Carex capillaris and the orchids Gymnadenia conopsea, Cyperipodium calceolus and Ophrys insectifera. The first observation in Sweden of the rare moss Bryum wrightii was made here in 1992. The Site is important for migratory water fowl and for breeding birds including the globally endangered common pochard Aythya farina, and a number of nationally endangered species such as the ruff Philomachus pugnax and the garganey Anas querquedula. The calcareous lakes and the Semsån stream provide important spawning areas and nursery habitats for several fish species including the burbot Lota lota, northern pike Esox lucius, perch Perca fluviatilis and Eurasian minnow Phoxinus phoxinus. The Site is frequently visited by bird watchers; three bird-watching towers and three resting places are accessible through boardwalks and footpaths. The main threats to its ecological character are of low impact. Under the EU Life project “Life to ad(d)mire”, restoration activities were carried out to raise the water level of the lakes, which had orginally been lowered by a ditching project in the late 19th century.
