Forests and mires

Puurijärvi Lake

The forests and mires of the Puurijärvi-Isosuo area will be restored to their natural state. The mires will be restored by blocking ditches and by removing tree stands from about two hundred hectares. The forests will be treated in an area of several dozen hectares. Decayed wood will be produced and growth space for deciduous trees will be opened up by the removal of planted conifers.

The natural state of mire areas in many places has been changed by drainage, the main aim of which at one time was to increase the area of land under forest management. The drainage of mires has affected water management.Mires have dried out in places, which has had a detrimental effect on the living conditions of many species that require a marsh habitat.

The area's woodlands have also been used for forestry. Logging and forest planting have been carried out in them. This has affected the structure of the forests and the age of the tree stands. In general, woodlands that have been used for forestry lack the phases of life of tree stands, such as decayed wood, that are found in natural-state evolution. Many forest species which are rare and few in number favour or require ancient or natural state forests for their habitat.
