Abstract:

 


The purpose of this study was to analyze and to compare the data on the vital state and timber volume of primary weakly disturbed pine forests and of secondary pine forests formed under different kinds of anthropogenic impact, such as: selection cutting, clear cutting, aerotechnogenic pollution by wastes of timber, pulp and paper works. Objects were 137 permanent sample plots were launched in pine phytocenosises of different types (lichen, green-mossy) growing in taiga zone of the Komi Republic (European North-East of Russia). To estimate the vital state of tree stands, the index of stand disturbance was calculated by the formula for determining the weighted-mean class of damage to the trees comprising the stand. Primary and secondary pine forests formed under different kinds of anthropogenic impact were compared as to mean annual stems wood increment. It is shown the vital state of the secondary pine forests is inferior to that of the primary pine forests. Exposure to emissions from the pulp and paper industry leads to a decrease both in the vital state of stand and timber volume. Received during the first stage of researches results of plants biodiversity, structures, productivity and vital state condition of primary and secondary pine forests stands further will be used for assessment of a degree of various anthropogenic disturbances and ecological zoning of territory of the Komi Republic.

 

Keywords: Forest monitoring, forest felling, wood increment and volume.
