The Oak genus (Quercus L.) is one of the most important genera of beach family (Fagaceae) that has ecological and economical importance. Chestnutleaf oak (Quercus castaneifolia C.A. Mey.) is native to Iran and distributed in Hyrcanian forests. Pure and mixed stands of this taxon have covered about 6.5 % of Hyrcanian forests. This study was undertaken to evaluate the effects of ecological factor...

Human demand for food and energy has led to significant changes in the level of reactive nitrogen (Nr) released atmosphere then deposited biosphere. This study aimed investigate artificial N deposition's impact on forest floor soil chemical properties an oak (Quercus castaneifolia C. A. Mey) plantation north Iran. Twelve plots 200 m2 (20 m × 10 m) were set up area. Four treatments considered: z...

initial growth of quercus castaneifolia (c.a.meyer.) seedling in competition with rubus fructicosus l. was investigated in a caspian lowland intervened forest located in noor city, north of iran. the research was conducted as factorial experiment in three replications. for this purpose, seedlings of 3 and 5 mm in collar diameter (cd) were planted in areas a (covered with rubus), b (without rubu...

Abstract Key message A vegetation analysis revealed the extent of recolonization by native a 25-year-old Cupressus spp. plantation in northern Iran. young indigenous Quercus-Carpinus community replaced conifers low-slope areas with deeper, heavier, and more fertile soils. Context Reforestation degraded or clear-cut-harvested lands can modify site conditions, facilitating succession reestablishi...
