Regeneration of pedunculate oak on the eastern border of its distribution range under the canopy of other tree species
The analysis of the seed regeneration of the pedunculate oak which observed on the eastern border of the species' distribution range (the Southern Urals) under the canopy of scots pine and silver birch is presented in the article. Despite the absence of parent trees in the nearest stands, the undergrowth and young are quite numerous (1,633 individuals per ha), they are represented by plants of different ages, show a relatively high radial increment (up to 4,8 mm per year) and a small proportion of individuals with growth and development disorders (23,7 %). The conclusion is made about the role of the of the pedunculate oak seeds distribution outside the oak forests and the species potential to expand of the distribution range in favorable ecological conditions.
