Data-set 9:

Venehlampi study area, Russian Karelia

Sampling frame: 4 x 8 km area within the planned Kalevala National Park, Northwestern Russian Karelia.

Field methods: 0.5 hectare study plots (transects). Three randomly selected study plots were enlargened into a size of 1 hectare.

Selection of study plots: The study area was transected by five parellel lines. Stady plots (transects) were placed on random points along these lines, so that the starting point of each transect was plased on the line, and the direction of the transect was randomized. The points hitting open mires were abandoned.

Amount of data: 27 independent study plots, altogether 15 hectares. The sample plots included altogether 5264 dead trees, of which 3230 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: In 1998 Mariko Lindgren, Toni Pöntelin and Sanna Honka. In 1999 Mariko Lindgren, Olli Manninen, Ismo Eriksson, Kirsi Eskelinen, Iira Nuutinen and Matti Ikonen.

Time and duration of field work: August 29. - September 5. 1998 and 4.-12. September 1999. Altogether about 20 days (about 87 per-person field days and about 18 per-person travelling 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.

In 1998 field-period the financing covered the salary of Lindgren and travel and food -expences of the field team. In 1999 the financing covered only the salary of Lindgren.

Notes: Dead-tree data is saved in a data-base. Identification of specimens is still going on.
