Torronsuo National Park. 02/02/04; Southern Finland; 3,093 ha; 60°44'N 023°37'E. Natura 2000 SPA, SCI, National Park. The largest mire area still in natural state in Southern Finland, including a complex of five interconnected active raised bogs, bog woodland and pools. The middle parts are characterized by ombrotrophic, pine and hollow bogs. Wet fenny strips alternate with elongated dry hummocks, together with hundreds of small pools. Sedge fens and shrub-pine swamps occur on edges of mires and of forested islands. Only small areas of forest with mineral soil occur in the National Park. The site supports a valuable wetland bird fauna and is an important staging area for Cranes during migration periods, peak counts reaching 1,000 individuals in autumn. The lowering of water level and nutrients leaching from surrounding fields have caused eutrophication and overgrowing of Lake Talpianjärvi, which has been reduced by drainage to a marsh. Restoration of mires was carried out under an EU Life project in 1996-99 in an area of 150 ha. The wetland provides significant services such as maintenance of water quality, environmental education, scientific research, outdoor recreation and birdwatching. Ramsar site no. 1536.
