The wetland Wallin’s Oasis
Together with the Åland Government, the Foundation has created a wetland near Kastelholm Castle in Sunds municipality. The wetland is signposted and is easy to visit. Link to Google Maps
Why a wetland?
A wetland works like a sponge that slows down water flow and acts as a filter for nutrients. Created wetlands are particularly effective in agricultural landscapes to reduce runoff from farmland before the nutrients reach the sea. Besides reducing eutrophication, they also benefit birdlife and biodiversity, since new valuable habitats are formed for aquatic plants, birds, amphibians, and other water-dwelling animals.
The purpose of Wallin’s Oasis is also to offer the public, especially children and young people, an opportunity to get to know a wetland and learn why wetlands are important and how they work. Åland’s Nature School regularly uses the wetland in its teaching. Three information boards next to the wetland explain why it was created, who Wallin was, about the plant and animal life in the wetland, and how a wetland functions.
Wallin’s Oasis is a joint project between the Baltic Sea Foundation and the Åland Government, with PAF and Ålandsbanken as funders.
