Restoration and management tasks

In the course of the project many different restoration and management tasks will be performed. The restoration of Puurijärvi Lake, including the raising of the water level and excavation work, is the largest of these tasks. Restoration of shore meadows and flood plains, as well as restoration of marshes and forests, will also be carried out during the project. The living conditions of the birds at Raijalanjärvi Lake will also be improved by feeding them.

Why is the natural environment to be restored and managed?

The aim of restoration and management work is to improve the quality of protected environments and the living conditions of various species. The background to the natural diversity of wetlands is usually some kind of human activity. The lowering of lakes in order to drain surrounding agricultural areas is the underlying reason for the formation of many Finnish wetland areas. However, in the long term, many of these kinds of bird lakes are at risk of becoming marshy and overgrown - a process which is accelerated by a general trend towards eutrophication and, amongst other things, the drainage of shore areas. When the lakes become overgrown, valuable species that are characteristic of wetlands disappear.

The open, low-growing shore meadows of wetlands are also usually the result of the use of the area. Shores have been used for grazing and grass has been harvested from them. Reed beds and bushes have grown on open shore meadows that have been grazed or mowed, and then many species have become endangered.

The conservation of the natural features of wetlands requires regular management or restoration. In assessing the necessity for restoration and for the conservation of wetland countryside, consideration must be given to the fact that a similar environment is no longer created in the same way as it was previously. Land use is currently controlled and restricted so that conservation of diverse wetland habitats requires investment in the management and restoration of the remaining areas.

Part of the project's restoration work will lead to restoration of the areas' natural states and development in accordance with those states. The aim of the restoration of mires is to return drained mire to its natural state, and to restore the primordial landscape at the same time. The aim of the restoration of forests is to accelerate the return of woodland that was formerly commercially forested to something resembling its natural state. The natural features of these environments require that their natural state be enhanced so that after the restoration work, the areas can be left to evolve without regular management.
