Forest roads play an important role in providing access to forest resources. However, they can significantly impact the adjacent soil and vegetation. This study aimed evaluate effects of road geometry (RG) on chemical biochemical properties soils assist environmentally friendly planning mountainous areas. Litter layer, canopy cover, organic carbon (SOC) stock, total nitrogen (TN), activity dehy...

The Cloud Ocean phenomenon in the Hyrcanian Forests, listed UNESCO World Heritage List, is one of most stunning yet lesser-known ecotourism destinations that has recently attracted attention adventure tours. However, increasing number ecotourists visiting these sites expected to threaten sensitive ecosystem sites. Therefore, this study aims conceptualize sustainable behaviors for off-road fores...

In this research, we used the integration of frequency ratio and adaptive neuro-fuzzy modeling (ANFIS) to predict landslide susceptibility along forest road networks in Hyrcanian Forest, northern Iran. We began our study by first mapping locations during an extensive field survey. addition, then selected landslide-conditioning factors, such as slope, aspect, altitude, rainfall, geology, soil, a...

Environmental gradients are important factors that can potentially influence the genetic diversity and differentiation of populations. The present study examines effect environmental heterogeneity Hyrcanian forests on populations Circaea lutetiana L. (Onagraceae). Using morphometrics, scanning electron microscopy (SEM) leaf epidermis, molecular markers, we analyzed among nine from environmental...
