An old marsh is being restored in Reisjärvi - the goal is to protect biodiversity

This fall, Metsähallitus will restore the bog in Ukonmurronneva in Reisjärvi. Swamps are one of the most degraded natural habitats in Finland.

An old swamp area with stunted forest. — With the thunderbolt, the trees have conquered the old open swamp after the drainage. In restoration, ditches are filled in and poorly grown trees are felled and left to rot in place. The goal is to return the bog back to its original open bog in the next few years.

Metsähallitus restores old swamp areas. One of the sites is Reisjärvi’s Ukonmurronneva, which, as a result of drainage, has changed from the original open swamp to a dense forest.

In addition to the thunderbolt, a nearby private nature reserve with a few streams flowing through it will also be restored at the same time.

In connection with the restoration, old trees are felled from the ditch lines and left to rot on the ground. After that, the ditches are filled.

The works will continue for about a month and can be used by hikers in the area, as the Peura trail runs on the west side of the area to be restored.

The work will be announced in the area with outdoor signs.

The goal of the works is to restore the water economy of the marsh as close as possible to the original one, and at the same time, the nature of the marsh is expected to gradually return to its former form.

Metsähallitus will monitor the success of Ukonmurronneva’s restoration in the coming years. There are also plans to continue restoring the marshes in the area.
