Data-set 11:

Mature, natural or seminatural pine-dominated forests in state lands of northern Häme, Finland

Sampling frame: Pine-dominated mature forests on dry to mesic sites in the state lands of the municipalities of Kuru, Ruovesi and Ikaalinen. Only stands which have not been treated by loggings during the last 50 years were included.

Field methods: 0.5 hectare study plots (transects).

Selection of study plots: Metsähallitus (Forest and Park service) provided a list of suitable stands. Of these Timo Kuuluvainen half-randomly selected the stands to be studied. The place and direction of the transect was randomized inside each stand.

Amount of data: 10 independent study plots. The sample plots included altogether 1272 dead trees, of which 735 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. Kaija Helle, Milla Hilli, Timo Kosonen, Ville Selonen and Petteri Tolvanen assisted for various periods.

Time and duration of field work: August - November 1999, altogether about 10 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:
In the municipality of Ikaalinen two sample plots on the Multiharju-ridge of the Seitseminen National Park.
In the municipality of Kuru three study plots in the Petäjäjärvi Nature Protection Area and one study plot north of the Petäjäjärvi Nature Protection Area. In addition one study plot west of the Seitseminen National Park.
In the minucipality of Ruovesi two sample plots in the Susimäki Nature Protection Area and one sample plot in the Helvetinjärvi National Park.

Notes: Specimens are identified and data saved in a data-base.
