Site description A diverse area west of Helsinki comprising many types of forest, small bogs, numerous lakes, ponds, hills, glacial ridges and rocky ledges. The most typical habitat is nutrient-poor heathland with Pinus sylvestris; patches of herb-rich deciduous forest and old, natural mixed forest are scarcer. Overall, the cover and continuity of forest is very good compared to most of southern Finland. Recreational activities are common all-year-round, however, these are mainly restricted to a wide network of natural and wooded tracks; some parts of the area remain relatively unused.

Key Biodiversity Phylloscopus trochiloides (15-25 pairs), Glaucidium passerinum (10-20 pairs), and Ficedula parva (10-20 pairs) also breed.
