Two fungi, V. heterodoxa and P. vaccinii, are found to have impact on the leaf coverage of bilberry plants. When studying vegetation or forest ecosystems, assessors should, therefore, be aware of the biotic impact of pathogens on plants.

Structural changes in the sawmilling industry imply more wood transport as distance between sawmills is increasing. One of the factors that determines the potential for economies of scale is the trade-off between reduced production costs and increased transport costs. The methods used in this study are based on geometric properties of wood procurement areas.The effects of the distribution of forest (area coefficient) and the road net (winding coefficient) upon average transport distance was explored, and considerable regional variation was found.The transport net factor (t) is the product of the area coefficient (a) and the winding coefficient (w) and gives a relative measure of the potential for efficient procurement logistics with respect to the distribution of productive forest area and the road net. The transport net factor is estimated for two wood procurement areas in each of four regions.When studying the sawlogs procurement in regions with different density of sawlogs buyers, average transport distance increases relatively more in areas where several buyers are competing for a limited timber supply than in areas with few competitors.
