The Efficiency of Mechanization in Weed Control in Artificial Regeneration of Oriental Beech (Fagus orientalis Lipsky.)
In this study which has been conducted in Akçasu Forest Range District of Devrek Forest Directorate; 3 methods (weed control with labourer power, cover removal with Hitachi F20 Excavator, and weed control with agricultural equipment mounted on a Ferguson 240S agriculture tractor) were utilized in weed control efforts in regeneration of degraded oriental beech forests have been compared. In this...
متن کاملEvaluation of non-destructive Meyer method for determination of bark volume of beech (Fagus orientalis Lipsky) in different geographical aspects
The non-destructive Meyer method was evaluated to determine the bark volume of beech (Fagus orientalis Lipsky) stands in north of Iran. The sample size was 185 standing trees collected from 4 geographical aspects (north, south, west and east) aspects. The constant k values and bark thickness (2e mm) of 185 standing trees were used to calculate the bark volume by the Meyer method. In this study,...
متن کاملClassifying Oriental Beech (Fagus orientalis Lipsky.) Forest Sites Using Direct, Indirect and Remote Sensing Methods: A Case Study from Turkey
Determining the productivity of forest sites through various classification techniques is important for making appropriate forest management decisions. Forest sites were classified using direct and indirect (site index) and remote sensing (Landsat 7 ETM and Quickbird satellite image) methods. In the direct method, forest site classifications were assigned according to edafic (soil properties), ...
متن کاملDetermination the structure of oriental beech, Fagus orientalis Lipsky stands (Case study: Asalem watershed forests, north of Iran)
Modification of stands’ structure and managing them using silvicultural methods close to nature and single selection system require information on status of structure, determining the target diameter, basal area and suitable volume to result in long-term equilibrium and sustainability. So, this study was conducted using the selection sample statistical method by selecting five 1-ha sample plot...
متن کاملInfluence of gap size and development stages on the silvicultural characteristics of oriental beech (Fagus orientalis Lipsky) regeneration
We studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, Langa forest, watershed 36: Kazemrood) of the Caspian beech forest in N Iran. Two transects, each 2 m wide, were laid along the longest (N-S) and shortest (E-W) axis of each gap. Five micro sample plots, each 4 m2, were established: one at the center, and one at each corner. Q...
متن کاملRemoval of Lead from Aqueous Solutions using Fagus orientalis Lipsky: Box-Behnken Experimental Design
Fagus orientalis Lipsky tree leaves, which are abundant in Iran, were evaluated for removal of lead from aqueous solutions. The optimization strategy is carried out by using two level full factorial designs. Results of the two levels full factorial design (2) based on an analysis of variance demonstrated that the initial pH, contact time and concentration of biomass are statistically significan...
