Growth analysis of the lower layer trees in forest stands under conversion in the Starohorské vrchy Mts.: A case study

The case study analyses the structure and dynamics of diameter growth on example two fir-spruce forest stands under conversion to a selection forest. In series 51 circular research plots (size 500 m2), biometric characteristics (tree species, at breast height, height) all stems with above 8 cm were registered. From selected stems, we collected cross-sections 178 tree cores in total performed age analyses. addition, for lower layer trees, assessed competition by neighbouring stand quantified index. results confirmed differences structure, despite similar distributions investigated stands, as well spruce fir layer. Nevertheless, was not proven significant factor trees.
