Modelling the demographic sustainability of pure beech plenter forests in Eastern Germany

Study of ectomycorrhizal fungi with beech trees in highland beech forests (Farim, Mazandaran province)

In this study, the ectomycorhizal fungi from beech trees in highland beech forests of Farim (Mazandaran province) were identified based on extraction of DNA from roots and sequencing the ITS region of nuclear ribosomal DNA. For this purpose, in the altitude of 1500-2100 meters A.S.L, 30 plot and one plant per each plot were selected randomly and samples were taken from roots in depths of 10 cm ...

Investigating the Structure of Beech Stands in the Gap Making Phase (Case study: Asalem Forests, Guilan)

Forest structure consider the spatial arrangement of trees characteristics such as age, size, species, gender and so on is.This study aimed to investigate the structural diversity of three one-hectare stands in the gap making phase, were studied. For this purpose, three sample plots with a one hectare area were selected in Asalem beech stands which belonged to the structural features of the gap...

Sustaining Oak Forests in Eastern North America: Regeneration and Recruitment, the Pillars of Sustainability

Oak cover types comprise half of the forestlands in the eastern United States. There is a great desire to sustain these highly valued forests. Unfortunately, reports of the successional replacement of oak are all too common, as they are throughout the world. Sustaining the oak resource requires the ability to both regenerate and recruit oak into the overstory as dominant mature trees. Too often...
