In the context of climate change and global warming, a growing number of studies reported lengthening of the growing season for most of the Northern Hemisphere, which is associated with increase of air temperature. Evidences of the increase of the growing season length were noted through satellite data and phonological and meteorological observations. This article presents the studies on the temporal...
Armillaria root disease is one of the most important diseases causing losses in forestry, horticulture, pomiculture and agriculture. Fungi from Armillaria spp. infest roots and stem base in trees and shrubs, causing white wood rot. In Poland the most common species include Armillaria ostoyae (Romagn.) Herink, found both in coniferous and deciduous stands, and A. gallica Marxm. et Romagn. found in...
OpenStreetMap (OSM) is a collaborative project covering the whole World with topographic data. Data are edited by volunteer users on the basis of satellite images, ortophotomaps and GPS traces, therefore are of diversified quality, especially completeness and positional accuracy. The aim of this study was to evaluate the usability of OSM forest data for Poland. We proved that positional accuracy,...
The paper presents the ideas of sustainable development with regard to the specific forest issues and management of its resources. We consider two main directions of forest use, which have the greatest impact on the condition of forest environment, i.e. logging and recreational use of the forest. This confrontation shows how effective the instruments of sustainable development are in collision with,...
Nanoparticles are gaining ever−wider application in plant production (for both agriculture and forestry), in the role of pesticides, as well as stimulators of plant growth and resistance. We sought to determine the efficacy of silver and copper nanoparticles (AgNPs and CuNPs respectively), used as seed dressings or subjected to foliar application, in affording protection from parasitic damping−off...
European mistletoe (Viscum album L.) is a semi−parasitic plant attacking selected tree species. It adversely affects the functioning of its hosts especially at water management level. Scots pine infestation by mistletoe subspecies Viscum album ssp. austriacum becomes more and more common. Mistletoe has been proven to have a negative impact on Scots pine cones, seedlings and seeds quality. Thus, we...
Cavities are important, natural components of forest ecosystems, conditioning the high level of biodiversity. They are formed either as a result of a natural process of wood decay caused by fungi or as excavations made by woodpeckers Picidae. Distribution and density of cavity trees are regionally diversified and dependent on species composition and age of the stands as well as the management way...
The purpose of the research was to develop and evaluate the accuracy of various methods for determining the volume of the butt−end (from 0 to 6 m) and middle (from 6 to 12 m) logs of silver birch. The material was collected on 84 samples plots established throughout Poland. On each plot, 2 to 10 trees (722 in total) were felled and measured using a cross−section method. The average age of the measured...
