Halophytes may change different soil properties and nutrients availability by organic materials addition to soil and soil conservation against erosion agents. Destroying these lands and halophytes may have an undesirable effect on environment. To study the effects of physiographic position, plant...

Regarding the effects of climate change and the recent drought in Iran, it is necessary to assess the growth and production of poplar varieties under drought stress. In this research, 14 clones of black poplar (Populus nigra L.) were studied during 2001-2008 in Sanandaj, Kurdistan province....

This study was conducted to protect the genetic properties and propagation of 4000-year-old Abarkooh horizontal cypress (Cupressus sempervirens L. var. horizontalis (Mill.) Gord.) by tissue culture technique. In the first experiment, the effect of preparation time of explant (four seasons), medium...

Interspecific interaction of tree species is an important process in establishing spatial structure of species associations in ecosystems with low species diversity. This study was aimed to investigate the interspecific interactions of Montpellier maple (Acer monspessulanum L.) and two accompanying ...

Forest stand structural development occurs over time and is commonly studied based on initial, optimal and decay developmental stages. The purpose of this study was to evaluate the capability of non-spatial indices for differentiating among developmental stages of beechhornbeam stand in...

The purpose of this study was to investigate reforestation projects based on the principles of sustainable development in the Darabkola watershed in Mazandaran province. Therefore, a goal programming model was used for the consideration of multiple goals. A fuzzy hierarchical process was used to...

The fruit production and regeneration status of Emblica officinalis was studied under two harvesting regimes during 2015-16 in a semi-evergreen forest of Manipur. The fruit production varied significantly (p>0.05) between harvesting regimes and years, attaining higher values in low harvesting...

Water was considered an inexhaustible natural resource until reality has proven its reverse. Climatic changes increase the pressure on surface runoff and groundwater, amplifying regional differences. As such, the necessity to adapt to climatic changes implies applying certain biologic/silvicultural ...
