Restoration projects of lakes

Espoo lakes Pitkäjärvi and Lippajärvi are both eutrophic lakes and popular recreational areas located in the vicinity of Laaksolahti and Viherlaakso. Numerous restoration measures have been carried out in the lakes since the 1970s, including management fishing and oxidation, but there is still room for improvement in the ecological states of both lakes. Restoration plans were drawn for the lakes in 2019, and new restoration measures in accordance with the plans were launched in 2020. The project has received funding from the former Centre for Economic Development, Transport and the Environment (now the Economic Development Centre).

Lake Loojärvi is located in between the City of Espoo and the municipality of Kirkkonummi. A scattered loading study and restoration plan were prepared for Lake Loojärvi in cooperation with Kirkkonummi in 2020. 

Lake Matalajärvi is a small, eutrophic lake situated next to Lake Bodominjärvi. The lake is a part of the Natura 2000 conservation area and an important area for aquatic birds. The state of Lake Matalajärvi is monitored, and Metsähallitus has been studying its vegetation in recent years. As a part of bird conservation, small predator hunting is also carried out in the area. A management and usage plan is currently being prepared for Lake Matalajärvi as a part of the Nuuksio area’s management and usage plan.

Lake Hannusjärvi is a small, eutrophic lake situated in Kaitaa, Espoo. A management and usage plan for the lake was completed in 2021. The lake’s conservation and restoration is promoted by a local residents' association by the name of Espoon Hannusjärven suojelu.
