spatial height variability - Opis:
- The influence of artificial elliptical gaps (size 15 and 20 are) on height of young (6 and 10 year old) planted pedunculate oaks was investigated on fresh mixed−coniferous and fresh mixed−broadleaved forest site types. For each combination of age, site type and gap size four gaps were sampled. In each gap, 3 circular sampling plots of 3 m radius were placed in northern, central and southern part of gap. The analysis were carried out separately for 6− and 10−year−old oaks and proved that gap size did not have an influence on height of younger and older oaks. In both cases, site type influence had statistical importance, but the practical silvicultural importance of this difference was only for older oaks. The position within gap was not important for growth of younger oaks, but had an influence on the height of older ones in different manner in different site conditions. The mean height of older oaks growing in more fertile conditions had maximum value in the centre of artificial gaps and diminished towards the periphery. On less fertile site types older oaks were the lowest in the northern position and their height in southern and central part of gaps was comparable.
