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...

the application of stepwise multivariate-linear regression models for determination of particleboard properties based on structural factors was studied. poplar (populus alba), beech (fagus orientaleis) and hornbeam wood (carpinus betulus) with dry density of 460, 630 and 790 kg/m3,respectively, were used as raw materials. three levels of boards target density (520, 620 and 720 kg m-3) and urea ...

aim of this research was evaluated and compared of density (number tree per hectare), basal area and volume characteristics for estimation of tree species diversity in degraded forests. in order to, 73 hectares of kouhmian forests was inventory based on random systematic pattern with circular plots (10r and 26 plots). in each plot species, dbh and number of tree were measured and recorded. to e...

the aim of this study was to develop a methodology to identify suitable habitat of the eurasian nuthatch (sitta europea) at kheyrood forest, northern alborz, iran. this study was carried out during spring to summer 2008. with attention to the area and topographic condition of kheyrood forest, patom, namkhane, gorazbon, cheler and baharbon were selected as data collecting series. the present stu...
