spatial height variability - Opis:
- The study presents spatial variation in the height of a 12−year−old oak regeneration in the north−south and east−west gradients in the cut patches with a similar width (28 m) but differing in length (33−70 m), with the longer side facing east−west direction. A comparison of the cut patches with an area of 7, 11 and 16 ares showed that oaks in large patches were on average 25% higher than in small patches and the diversity of trees in the WE and NS gradients depended on the size of the patch. In each case, the lowest trees occurred in the zone of strong root competition of shelterwood, whose influence decreased with the enlargement of the cut patches. The results of the study show that the establishment of large (15−20 ares) elliptical or rectangular patches whose area can be expanded by lengthening the axis in the east−west direction is the recommended method of pedunculate oak renewal in forest practice.
