Main classes of birch MAIN SPECIES OF GENUS BETULA (BIRCHES) Among the 60 species of the genus Betula, we could emphasize the following: Main species of birch in Europe and Asia Silver Birch: (Betula pendula Roth = Betula alba = Betula verrucosa Ehrh) deciduous tree or shrub in the famil...
birchbrowsingmooseplant-animal interactionSwedenIn Sweden, moose (Alces alces) feed to a large extent on birches (Betula pendula and B. pubescens). This study examined responses of juvenile birches to moose browsing and the responses of moose to browsed trees. Following browsing, the birches ...
(Acer rubrum), striped maple (Acer pensylvanicum), red oak (Quercus rubra), paper birch (Betula papyrifera), yellow birch (Betula alleghaniensis), and uncommon species was expressed with a tree species influence index (TSII) based on the size of the individual trees of each species and ...
A dynamic volume and biomass growth model system for even-aged downy birch stands in south-western Europe This study develops some components to complete a management-oriented dynamic model system for simulating current and future volume and biomass of even-age...

Downsizing the training set from 30% to 2.5% of all trees had only a marginal effect on the performance of classifiers. The intensity features were dependent on the absolute and relative sizes of trees, especially for birch. The results suggest that leaf size, orientation, and foliage density ...
As a result of verifying applicability as national factors using the investigated factors, it could be assumed that the stem density (0.47 g/ cm 3 ) and biomass expansion factor (1.29 aboveground) in coniferous trees and the stem density (0.65 g/ cm 3 ) and biomass expansion factor (1.22 ...
It refers to the tree’s heavy wood. A hop hornbeam is a type of birch tree, and the wood from its European counterpart was typically used toyokeoxen. Because it was sturdy and thick, the wood served as a “beam” to yoke “horned” beasts of burden. Of course, some kept it more...

, downy birch (Betula pubescens Ehrh.), and common hazel (Corylus avellana L.) growing in coppice-with-standard systems in Lower Saxony, Germany. The parameterization was based on measurements of over 950 trees sampled from two forest sites. The sampled trees were felled and separated into ...
Interspecific competition between adult trees In the present work, one-sided interspecifc competition was found between some species of adult trees (≥4 cm DBH) in this temperate forest (Table 4). The one exception was for Q. liaotungensis and A. mono where symmetric competition was found to...
