[ 1 ] - ارزیابی روش نمونه برداری فاصله ای نزدیک ترین فرد به منظور برآورد تنوع زیستی در اکوسیستم جنگلی ارسباران

Species diversity protection will ensure the protection of natural processes and ecological values. Appropriate information on the condition and location of endanger species will facilitate the management and conservation of forest areas. The present study was conducted in Arasbaran forests for the purpose of evaluating two sampling methods including circular sampling (1000 m2 area) and the nea...

[ 2 ] - تأثیر گردشگری طبیعت بر ویژگی‌های ساختار و تنوع‌زیستی جنگل ارسباران

تنوع زیستی به‌عنوان یکی از پر اهمیت‌ترین معیارهای مدیریت گردشگری پایدار شناخته شده است و بازدید از مناطق جنگلی یکی از مهم‌ترین فعالیت‌ها‌ در بخش گردشگری طبیعت محسوب می‌شود. بنابراین توجه به این دو موضوع در کنار یکدیگر، کمک قابل توجهی به جنبه‌های مدیریت جنگل خواهد کرد. مطالعه حاضر به منظور درک بهتری از اثرات گردشگری در مناطق جنگلی ارسباران بر ساختار و تنوع زیستی این اکوسیستم صورت گرفت. نمونه‌برد...

[ 3 ] - Effect of Stand Structural Characteristics on Natural Regeneration of Acer Campestre L. in Arasbaran Forest

Natural regeneration is one of the key aspects of forest sustainability and a tool to decide on restoration programs in forest areas. The purpose of this study was to investigate the quantity of natural regeneration of Acer campestre L. as one of the most important tree species in Arasbaran forests and its relationship with elevation changes and structural characteristics in the natural stands....

[ 4 ] - Estimation of Density using Plotless Density Estimator Criteria in Arasbaran Forest

    Sampling methods have a theoretical basis and should be operational in different forests; therefore selecting an appropriate sampling method is effective for accurate estimation of forest characteristics. The purpose of this study was to estimate the stand density (number per hectare) in Arasbaran forest using a variety of the plotless density estimators of the nearest neighbors sampling me...

[ 5 ] - Investigation of the Allometric Models in Estimation of Poplar (Populus deltoides) Height

One of the most important issues in forest biometrics is the use of allometric functions to estimate the tree height by using diameter-height models. Measuring the total height of trees is usually a complex and time-consuming process. In allometric functions, the diameter is measured directly but the height of the tree is an estimate of an allometric model, which will be more accurate if the cr...

[ 6 ] - The effect of ecophysiography on the quantitative characteristics of DBH, height, basal area, crown diameter and canopy area of trees in mountain forest communities (Case study: Oak-hornbeam community in Arasbaran forest)

Ecophysiography is the geography of the earth and the relationship between physiography and the ecosystem. Ecophysiography is a basis for planning processes to study the characteristics of terrestrial systems concerning the interactions between terrestrial physiography and living organisms. Due to the current state of ecosystems and the increase in natural disasters for ecosystem sustainability...
