BIOMETRIC CHARACTERISTICS OF WOLVES TREES IN OAK SAPLINGS IN THE SULęCIN FORESTRY DISTRICT

Keywords: silviculture, sessile oak, nurture of common oak, wolves trees, sapling stand, diameter, height
Abstract:

Analyses were conducted in the Sulęcin Forest District. Measurement plots were established in two oak dominated saplings (Quercus robur L.), at the age of 17 years growing at different forest site types. The share of the so-called wolf trees was low (4%) and varied from 222 to 267 individuals per hectare. In this paper we presented the measurement of tree height (h), diameter of the breast height (d1.3), slenderness (m/cm) for all living trees (D-w). These results were compared to the results obtained for the groups of trees (D-r, D-s and D-p). It was stated that wolf trees (D-r) dominate in size, independently of the forest site type. On average, they are 35% higher than the other trees. They are also thicker, almost twice, than the rest of trees. Silvicultural operations (tending treatments) in saplings should take into consideration the influence of the wolf trees (D-r) on the other trees, as well as on the stand structure.
