Where train tracks bisect moose habitat, trains may collide with moose, impacting the local population and creating a safety concern for rail traffic. Understanding the patterns underlying these collisions, is critical for helping managers choose the right mitigation methods to reduce mortality on railways. Our objective was to analyze the long−term temporal patterns of moose−train collisions. We...
The intermediate cuttings have an important impact on the stand structure and productivity. Choosing the right method of the treatment performance is the decision, which is fundamental in shaping tree stands stability. The radial increment, apart from the natural growth potential of particular species, is influenced by many abiotic, biotic and anthropogenic factors, among which one can distinguish...
One of the main tasks for the forest managers is to form the highly productive stands, and it is mainly performed by applying intermediate cuttings during the stand development. As the impact of thinning on the premature Scots pine, commercially most important species in Lithuania, has not been sufficiently investigated yet, our objective was to evaluate the impact of such treatments on the growth...
The aim of the study was to apply the forest soil trophic index (ITGL) in the assessment of post−agricultural soil under naturally regenerated silver birch (Betula pendula Roth.) stands. The study was conducted in Mazowieckie region (central Poland) in 10 locations (tab. 1). In each location we established 4 study plots with naturally regenerated silver birch of different age. The age of the investigated...
The objective of the study was to determine the impact of selected soil properties on site index of oak (Quercus sp.) stands in the Międzyrzec Forest District (eastern Poland). We utilised data rom the soil−habitat survey, which provided information about physical and chemical properties of soils and stand descriptions for 21 oak stands (tab. 1). The collected data served to determine site index (SI),...
The objective of the study was to determine the quantitative and valuable potential of wood resources of black locust (Robinia pseudoacacia) and Douglas fir (Pseudotsuga menziesii) in individual regional directorates of the State Forests (RDSFs) in Poland. We used data from the State Forests Information System database (values for the end of 2014) to determine the amount of the resources of the analysed...
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised information available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In...
The paper presents the dendrochronological analysis of silver firs (Abies alba Mill.) growing in the canopy layer of the forest stands. We searched for the similarities in the rhythm of radial growth of studied trees and we analysed the response of these stands to the increment disturbances related to the occurrence of adverse climatic factors and the pressure from industrial pollution. The research...
The main aim of the study was to compare the radial growth of Persian walnut and Schrenk spruce trees growing under the same ecological conditions in the Sary-Chelek range of the Tien-Shan Mountains, as well as to analyse the response of these species to the selected climate factors in line with the altitude gradient. Four study plots were established at the altitude of 1350, 1400, 1450 and 1500 m...
