Slenderness of 30-year stand larch (Larix decidua Mill.) and its relationships to other biometric parameters
Summary.

Introduction. Presented study is focused on the analysis of the correlation between slenderness (s) of larch (Larix decidua Mill.) and chosen biometric characteristics, growing at the mixed fresh coniferous forest site type.

Material and methods. Data were collected on three plots being the part of the permanent experimental plot of the Silviculture Department, located at the Siemianice Forest Experimental Station. Geographic location 51°12´N and 18°03´E.

Results. At the age of 30, the unattended larch tree stand has a two-layer structure. Trees characterized by the high values of the average slenderness index, s = 1.25 (m/cm). It was found that the average height (h) was 14.6 m, and the average diameter (DBH) – 12.15 cm. Results showed that s index is correlated with few biometric traits of trees. Additionally, it was found that the correlations of slenderness with other features of larch lose strength with the deterioration of biosocial position in the stand. The most strongly associated trait with slenderness is the tree breastbone (DBH) - independently of the biosocial position, followed by the width of the crown (dk ).

Conclusions. The 30-year-old larches growing in unmanaged stands, due to their large slenderness, are unstable, and thus may be less resistant to harmful effects of wind and snow.

Key words: silviculture, larch (Larix decidua Mill.), slenderness, height, diameter
