Compacted soil has lower water infiltration and hydraulic conductivity, which contributes to increased runoff erosion on slopes. The aim of the present study was assess sediment three skidding trail longitudinal gradients (15%, 25%, 35%) different levels machine traffic (low, medium, high), over a two-year period following impact in Hyrcanian forest, Iran. results show that gradient intensity have significant effect bulk density total porosity skid trails. average amount varied significantly...
We address two main challenges facing the implementation of sustainable forest management (SFM) in Hyrcanian Iran: inconsistent policy and use outdated science techniques. propose Sustainable Forest Management Model (SHFMM) as best currently available solution to achieve improved northern forests Iran. The suffers from a lack scientific knowledge state-of-the-art technologies. There is pronounced difference mindsets older new-school forestry scholars regarding how approach these...
A field production study was conducted for a manual harvesting system using chainsaw in Caspian hardwood forest site. selective cut performed on 42-hectare tract with an average slope of 30 percent. Felling time per tree most affected by diameter at breast height and the distance among harvested trees. The gross net rate 20.6 m3 26.1 hour/one person, respectively. unit cost considering 1.05 USD/m3 0.81 USD/m3, significant variables included (D) trees (L) expenditure model. This regression...
The purpose of this article is Artificial Neural Network (ANN) modeling using ecological and associated factors with forest degradation to predict the ecosystem, thereby enabling us assess environmental impacts projects as an Environmental Decision Support System (EDSS). Results Multi-Layer Feed-Forward (MLFN), trained for Optimized Forest Degradation Model (OFDM), indicate that performance OFDM more than other models. Changes in management activities higher value sensitivity analysis help...
Natural treefall gaps have a substantial role in maintaining soil and plant diversity old-growth forests. However, the amount of information on effects recovery physical chemical properties compacted soils is scarce. We tested hypothesis that natural accelerate restoration by enhancing biological microbial activity topsoil after period five years. Five years ground-based skidding operation Hyrcanian forest, levels were compared among different treatments including canopy with an area 200 m2...
Along the coastal strip of tropical and subtropical regions, mangrove forests extend as one most productive ecosystems.Iran is considered western habitats these communities in Asia.Unfortunately, recent years, despite their economic ecological importance, have been threatened mainly due to human activities, which necessitate need for protecting developing ecosystems.Ex-situ conservation, aims transfer a species right place preservation development, effective ways forests.It obvious that...
It has been widely recognised that the participation of different groups people is crucial to urban forest management. This paper aimed focus on motivating factors and conditions foster in Also, main constraints which limit were explored. Therefore, a survey using researcher-designed questionnaire was used gain information from visitors. Exploratory factor analysis categorise all effective into summarised factors. Using principal component analysis, it found most important encouraging...
Sustainable forest management is known as the most effective type of management. This mode aimed at enabling sustainable and comprehensive development in forest-related sectors. Practicing forests requires powerful tools order to ensure achieving objectives and, same time, direct processes a way. Forest plan suitable means carry out this monitoring. Though, tool set motion, scheme. certain proper criteria indicators practice. The have various applications within plan, including their...
The Hyrcanian (Caspian) forest in northern Iran has a richness of biological diversity, with endemic and endangered species, diverse range economic social conditions. With focus on low impact timber extraction small scale tree harvesting, the proportion mule logging recently increased. objective this study is to assess efficiency operations forests through comprehensive time study, further attempt identify opportunities for improvement. research was carried out Namkhaneh district Kheyroud...
