WHY PROTECT OLD-GROWTH FORESTS?

Within past five years Finnish forest industry, Forest and Park Service, forest owners' associations and some individuals have been bringing accusations against Finnish NGOs accusing us of spreading misleading and wrong information about Finnish forests. Despite of these accusations there have not been one single example of this kind of "wrong information" - and will not be. There is no reason for Finnish NGO's to invent own "opinions" on old-growth forest protection - results of official researches etc. are enough.

FINNISH ENVIRONMENT INSTITUTE:

The present network of forest reserves is inadequate in most parts of Finland

  • "Protected areas are needed to preserve biodiversity of forests, because managed forests are are mainly used for intensive tree production. The present network of forest reserves is inadequate in most parts of Finland (excluding Forest Lapland) in maintaining biodiversity of forests. On the basis of the present work, forest reserves should cover about 10% of the forest land (south of Forest Lapland).
  • Preserving natural, old-growth forests is important, as they are essential for several species groups. The estimate of the 10% of forest land to be protected was based on the critical thresholds of habitat fragmentation, on the systematic reserve selection to consist of all species in a particular group (land birds), on the minimum proportion of old-growth forests in the forest landscape and on the predictions of ecological models."

    MINISTRY OF THE ENVIRONMENT:

    Forestry has made the life of many demanding species extremely difficult. The numbers of species living in herb-rich forests and, in particular, in old-growth forests have declined markedly.

  • As a result of the intensified use of timber, trees are grown in general realtively young stands of the same age. The main species in commercial forests are pine, spruce and birch; there is a little of decaying wood.
  • Areas of wild forest are fragmented. The building of forest roads has brought mechanical logging to previously almost virgin areas.
  • Silviculture is extended to mires as well, which have been drained with a wiew to producing timber on peatlands. Originally, as much as a third of the country`s total surface area was covered with mires; now almost half of them, the majority in southern Finland, have been drained.
  • All this has made Finland a pioneer in efforts to secure sustainable timber production. It has, however, also made the life of many demanding species extremely difficult. In-depth studies reveal that forests shelter a good 40 percent of all Finland`s threatened plant and animal species. The numbers of species living in herb-rich forests and, in particular, in old-growth forests have declined markedly.

    FOREST AND PARK SERVICE:

    Due to human activities, every 15th known species in Finland is in danger of disappearing. In almost fifty percent of the cases, forestry is the main cause.

  • Old-growth taiga forests constitute one of Finlands original ecosystems. Their future is being determined now. The large number of threatened forest species is an indication that the ecological threshold has already been crossed beyond which logging endangers the ecosystem and causes extinctions.
  • There is little pristine old-growth taiga forest left, but there is a lot of commercial forest. Consequently, every time some of the former is cut, Finlands forest ecosystem becomes that much less diverse.
  • Old-growth forests are biologically considerably richer than commercial ones and they have a different species assemblage.
  • There are over 135 threatened species inhabiting old-growth forests, 64 of them being incapable of surviving elsewhere. The number of species preferrring, or compeletely dependant on, natural forests is far greater than the number favouring commercial forests.
