Wpływ szlaków zrywkowych na wzrost i rozwój drzew z nimi sąsiadujących

The paper presents research on dbh, height and biosocial structure of trees growing close to strip roads. Also, the length and height of tree crown were analysed. The studies comprised the trees localised along the strip roads as well as those growing 3 and 6 m away. The strip roads were cut 6 years before in the course of an early thinning in a pine stand. The thinning was conducted in three technological variants, which differed, among other things, in the width of the strip roads. The results confirmed the statistical significance of difference among some of the investigated traits.
