Hurricane winds are one of the most important abiotic factors in shaping structure forest and processes that occur it. The aim research was to determine regeneration changes stands caused by windstorm 1983. research, based on stand tables from years 1982, 1984, 1989 2014, carried out nine permanent plots Bia?owie?a Forest. mean number trees (MNT) taller than 1.30 m decreased 13.7% after windsto...

Since the early 2000s, reports on declining hornbeam trees (Carpinus betulus) are spreading in Europe. Two fungi involved decline phenomenon: One is Anthostoma decipiens, but other etiological agent has not been identified yet. We examined morphology, phylogenetic position, and pathogenicity of yellow fungal isolates obtained from Austria, Georgia Switzerland, compared data with disease norther...

Introduction: Due to the non-developed mechanization situation, chainsaw is a widely used tool in Iranian forests. This tool can trigger unwelcome disorders (e.g., white finger syndrome) due to the transmitted vibrations from its handle to the body members. Characterizing these vibrations can result in minimizing the intensity of these disorders. This study aims to investigate the effect of dif...

This paper documents data on standing dead trees (snags) in the pine-spruce (Norway spruce Picea abies, Scots pine Pinus sylvestris) natural stand in Bialowieza National Park (BNP) in northeast Poland. Trophically, this mostly coniferous stand represents one of the poorest habitats of the BNP, and this stand has never been cut. There are few tree species of significance, i.e., Scots pine, Norwa...
