Structure of the montane taiga forests of West Khentii, Northern Mongolia
montane taiga elevation deadwood regeneration
2015/4/14
Studies were undertaken to investigate the composition, structure and diversity of four different types of North Mongolian montane forest near the southern border of the taiga. These forest types, cla...
Long-term silvicultural experiment with transformation of the mixed stand structure
production regeneration species composition stand transformation
2015/3/27
The paper summarizes the main characteristics of a mixed stand during 80-year transformation to the mixed stand with permanent selective structure. The initial main stand was mostly composed of conife...
Different approaches to the classification of vertical structure in homogeneous and heterogeneous forests
height variability forest status survey NFI structural classification
2015/3/19
The paper shows difficulties in the evaluation of the forest status when considering forests with different height structure (uneven-aged forests). It is the main problem in categorizing such forests....
Diameter structure of the stands of poplar clones
diameter distribution function frequency distributions of diameters poplar clones Robusta I-214 Weibull function
2015/3/19
The construction of a continuous mathematical model of frequency distributions of the diameters of trees of poplar clones Robusta and I-214 in dependence on tree diameter and mean diameter of stand is...
Differences in the structure, species composition and diversity of primary and harvested forests on Changbai Mountain, Northeast China
broadleaved-Korean pine mixed forest forest structure species composition species diversity
2015/3/19
Broadleaved-Korean pine (Pinus koraiensis) mixed forest is a typical vegetation type in the eastern Eurasian continent. We compared the structure, composition and diversity of a primary forest and a l...
Horizontal structure of forest stands on permanent research plots in the Krkonoše Mts. and its development
Clark-Evans index forest stands Hopkins-Skellam index horizontal structure K-function Krkonoš e Mts. Pielou-Mountford index
2015/3/19
Horizontal structure on 38 permanent research plots is described for juvenile growth and developmental phases (natural seeding, advance growth, plantations) and tree layer of a parent stand. Hopkins-S...
Structure and development of forest stands on permanent research plots in the Krkonoše Mts.
forest development mountain forest structural diversity
2015/3/19
The research is focused on structure and development of forest stands from 5th to 8th forest vegetation zone in the Krkonoše Mts. The forest stand diversity according to tree species composition ...
Assessment of tree layer biomass and structure using aerial photos in lake catchments of the 妘mava Mts.
allometry altitudinal gradient Bohemian Forest
2015/3/16
The combination of georeferenced colour aerial photos and limited field measurements of individual trees was used to determine tree stand biomass in forests of prevailing Norway spruce. The technique ...
A study on the variation of morphological characteristics of silver fir (Abies alba Mill.) seeds and their internal structure determined by X-ray radiography in the Beskid S筪ecki and Beskid Niski mountain ranges of the Carpathians (southern Poland)
Abies alba X-ray seed viability
2015/3/16
The variation of the morphological characteristics and internal structure of silver fir (Abies alba Mill.) seeds from 4 stands growing at the altitude of 625?50 m in the Beskid S筪ecki and Beskid Niski...
The relation between the microscopic structure and the wood density of European beech (Fagus sylvatica L.)
beech juvenile wood mature wood vessels rays density
2015/3/12
The aim of this study was to compare the structure of beech juvenile and mature wood in relation to wood density. The comparative analysis between juvenile and mature wood examined the diameter of ves...
Structure of coarse woody debris in Lange-Leitn Natural Forest Reserve, Austria
forest association habitat fungi oak broadleaved forest
2015/3/12
The amount, variability and quality of coarse woody debris (CWD) in an oak-dominated natural forest reserve in Austria were studied in 2006. The average volume of CWD (snags and logs) was 107.3 m3/ha,...
