Forest types mapping is one of the most necessary elements in forest management and Silviculture treatments. Traditional methods such as field surveys are time-consuming and cost-intensive. Improving satellite data sources and classification methods offer new opportunities for obtaining more accurate forest biophysical maps. This research compares performance of three non-parametric and tree-ba...

We studied the modern pollen rain in two different landscapes from Hyrcanian lowland forests up to slopes of Alborz Mountains Gilan province for first time. Pollen traps were installed one year and moss samples collected along altitudinal transects 100 1800 m 2300 elevations. The results counting environmental DNA barcoding (metabarcoding) compared 32 locations. In total, 81 vascular plant spec...

Engineering applications can be used to mitigate the adverse effects of soil compaction and amend compacted soils. Previous literature has highlighted beneficial interventions such as litter mulching incorporation on skid trails. However, little is known about effectiveness these alternatives in restoring forest quality after logging. The objective this study was properly elucidate above mentio...

The Hyrcanian forests of Iran are mainly managed with the single-selection silvicultural technique. Despite significant ecological benefits associated selection cutting, this type forest management leads towards more challenging situations where it is difficult to maintain and practice successful forestry than in even-aged systems. Therefore, study provides relevant tools form models estimate l...

Background and objectives: Plants belonging to the genus Tilia L. (Tiliaceae) are often tall beautiful trees which are considered for various medicinal potentials of their flowers and leaves. The present study was an attempt to investigate the phytochemical constituents of Tilia rubra subsp. caucasica leaves from the hyrcanian forests of north of Iran. Methods: Chromatography on Silica gel (nor...

Pterocarya fraxinifolia (Lam.) Spach., a relict tree species of the Juglandaceae family, is native to the Great Caucasus, Anatolia, and to the Hyrcanian forests of the southern Azerbaijan and Northern Iran. In this study, the phylogenetic relationship of the species, sampled in selected Iranian populations, and the global biogeography of the genus Pterocarya were addressed. Leaves were collecte...

The patterns of diversity Lepidoptera and its relationship with environmental characteristics in the Hyrcanian forests northern Iran have not been investigated so far, while such studies are extremely effective restoring forest biodiversity. This study aimed to assess relationships between vegetation abundance Darabkola forest, Sari district (Mazandaran province, Iran). Light trapping yielded a...
