Data-set 7:

Old, intact or (only) selectively cut pine-dominated forests of state lands of southern Kuhmo

Sampling frame: Old, pine-dominated state-forests in southern Kuhmo. Only forests which have not been logged for the last 50 years have been included. Pine pogs and other paludified ares were excluded.

Field methods: 0.5 hectare study plots (transects).

Selection of study plots: Finnish Forest and Park Service provided a list of forestry compartments fullfilling the selection criteria. Of the listed compartments Timo Kuuluvainen selected 23 compartments "semirandomly" for the study. The location of a study plot, "transect", was randomized to each study-compartment so that the distance of the study plot from the compartment edge was, if possible, more than 50 meters.

Amount of data: 23 independent 0.5 hectare study plots, of which nine was intact and 14 selectively cut. The sample plots included altogether 2690 dead trees, of which 1741 were more than 10 cm thick.

Species included in the study: All wood inhabiting polypores and some other wood inhabiting fungi, see a list of target species.

Field workers: Mariko Lindgren. Riina Ala-Risku, Ismo Eriksson, Pia Juntunen, Tuuli Mäkinen, Olli Manninen and Katja Viberg assisted for various periods.

Time and duration of field work: August 20. - September 24. 1998. Altogether 17 days.

Funding: Part of the research project "Structure and dynamics of natural and managed boreal forest landscapes - Linking landscape pattern, stand structure and species diversity", financed by FIBRE (Finnish Biodiversity Research Programme), Academy of Finland. Specimen identification work has also been supported by the Mycology Department of Finnish Museum of Natural History, University of Helsinki.

Areas selected (sampled) for the study:
Selectively cut forests:

  • One study plot from the Jauhovaara nature protection area
  • Five study plots from the surroundings of Sortovaara, east of the Hiidenportti National Park
  • Eight study plots from the Jämäsvaara-Katajakankaat -area, south of the Kuhmo town center
    Intact forest:
  • Two plots from the Louhivaara old-growth forest protection area
  • One plot from the Honkavaara old-growth forest protection area
  • Six plots from the Ulvinsalo Strict Nature Reserve

    Results: Preliminary species results from the Jämäsvaara-Katajakankaat area has been given to the Forest and Park Service.

    Forest and Park Service has been informed about the findings of threatened species on the sample plots of all unprotected areas.
