THE DEPENDENCY OF THE QUALITY AND SIZE STRUCTURE AND OF THE VALUE OF TIMBER ON THE ORIGIN AND AGE OF STANDS
Anna Barszcz
ABSTRACT
Standing timber assessment shows that, in the area under research, it is spruce stands of artificial origin that are characterized by the best quality and value of timber. Rebuilt stands over 50 years old also gained high assessment with respect to the features under research. A relatively low assessment of timber quality in stands of natural origin may result from their advanced age and the fact of being protected as nature reserves. Timber quality in the area under research is also affected by the bedrock type and altitude.
Key words: timber quality, timber value, the origin and age of stands, stands of natural origin, monocultures, rebuilt stands..
