- There are sign crayfish in about 200 lakes and streams in Värmland, but there are only permits for seven lakes, says Jenny Monsén, environmental manager at the County Administrative Board in Värmland.

Signal crayfish carrying the disease plague is one of the biggest threats to river cancers. In the cross-border project, the goal is to produce an action plan that creates opportunities to preserve the crayfish in Swedish and Norwegian waters.

- They do not have as much signal crayfish in Norway and are keen to protect the waters at the border and it is also important in Värmland where there are signal crayfish in many waters while Värmland is a core area for the crayfish in Sweden, explains Jenny Monsén.

Eliminate signal crayfish and cancer plague

The hippopotamus project is funded with approximately SEK 7 million from the EU's cross-border cooperation program.

It is hoped that the project will develop methods for locating and eliminating signal crayfish and cancer plague in cross-border areas.

In Värmland, water within an area within Eda municipality down to a little south of Skillingmark is to be included in the project.
