We present research results of timber skidding by a Timberjack 450C skidder in the path cutting of pine trees in Shafaroud watershed. Time studies were conducted to quantify the productivity and perat...
The paper informs about partial results gathered and processed in the framework of the international research project “Learn for Work”, Leonardo da Vinci programme. The goal of the research project wa...
This article summarizes basic estimates of productivity and trend analysis of one of the principal introduced forest tree species in the Czech Republic, i.e. Douglas-fir (Pseudotsuga menziesii [Mirbel...
The transformation process of even-aged forest stands to irregular forest stands on waterlogged sites after 20 years effort was analysed. Data from two 1-ha PRP was analysed with special focus on stru...
A growing need for the evaluation of prospects and sustainability of forest resources calls for the availability of harmonized data on forest distribution. We described and evaluated nine datasets pro...
One of the factors in planning forest roads is average skidding distance which is calculated in projects from the map, according to forest road density, however it has a low accuracy. In this study re...
A road network in forest lands provides easy access to forest resources for extraction, regeneration, protection and recreation activities. Erosion from forest roads and skid trails is a major concern...
The paper deals with the issue of mapping the age composition of stand groups using hyperspectral imagery acquired by the AISA Eagle VNIR sensor in the Bíly Kříž locality in the Moravian-Sil...
Among other important factors, vegetation cover strongly affects the hydrological processes in mountain catchments. In this paper, we present the results of field infiltration measurements at the loca...
Average skidding distance for forest stands is an important parameter for the determination of the optimum road density and spacing. In this research the real mean skidding distance and theoretical me...
Information on the historical background of the present forest conditions is needed for proper decisions on forest management. Disturbances play a major role in the formation of forest structure and c...
GPS Trimble JUNO ST was tested at 16 points under forest canopy. The measurements were done on three different dates of the growing seasons in 2007 and 2008. On each date, 4 recordings were measured i...
The article describes natural, combined and artificial regeneration on 38 permanent research plots in both Czech and Polish part of the Krkonoše Mts. The attention is paid to species composition,...
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...
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 ...
