The aim of the present study was to analyse the impacts of different logging intensities after five years from logging including non-logged, low (3.4 felled stems per hectare), medium (5.2 felled stem...
In this study, 39 generalized height-diameter prediction models were developed for Oriental beech (Fagus orientalis Lipsky) in the Hyrcanian forest in Iran. Data were collected from 75 permanent sampl...
In northwestern Algeria, the production of Aleppo pine (Pinus halepensis Mill.) seedlings in four nurseries is hindered by the damping-off disease. Results obtained indicated that Fusarium spp. are co...
The present paper evaluates the height, diameter and stem volume of parental tree progenies. These Norway spruce progenies are compared with the control estimated from tables. The control was overperf...
Wild cherry is one of the noble hardwood species that increase the biodiversity of our forests and at the same time it could increase the income for forest owners. The preconditions for achieving thes...
Vegetative propagation of forest tree species is of great importance not only for breeding programmes but also for the conservation of valuable populations of tree species. Important is also a possibi...
The research was focused on exploring the dynamics and forms of regeneration processes and structural diversity of the Norway spruce virgin forest in Babia hora NNR in relation to altitude. In each ...
The paper describes modelling of forest development and its utilisation for forest management planning, specifically modelling of growth mensurational variables of the two main commercial species – sp...
Partitioning gross rainfall (GR) into throughfall (TF), stemflow (SF), and interception loss (I), which has a very significant effect on water balance and the nutrient cycle in forest ecosystems, was ...
We examined the species composition of soil seed banks (to 5 cm depth), using germination tests, for the Ooyamazawa riparian forest in the Chichibu Mountains. The canopy of this forest is dominated by...
This study examined the environmental conditions that were required to maintain a threatened species, Salix hukaoana. Twenty-five plots were set up in the riparian zone along the Yubiso River, and for...
Biotechnology in forest tree breeding research in Japan is summarized including some important research held in abroad. In DNA analysis it is very important to select adequate kind of marker for each ...
Increasing interest in non-timber forest products (NTFPs) has led to their greater recognition in sustainable forest management planning. This is evident in local resource management plans for the Ro...
Seed rain studies provide valuable information for forest researchers monitoring exotic species invasions. Plant species move through forests primarily as seeds, and this dispersal is critical to futu...
Western spruce budworm (Choristoneura occidentalis) is a defoliator of Douglas-fir throughout the tree’s range in British Columbia. Although recent defoliation levels within the Coast Forest Region (c...
