One of the ordinary methods to protect, rehabilitate, and enhance an ecosystem function in arid and semi-arid areas of the world is sand dune stabilization using biological practices. Plantation of species on the soil plays a great role in sustainable management of the ecosystem. This research studies the effects of cultivation of Haloxylon ammodendron and […]
There are some barriers for rangers to take part in range plan projects and evaluation. Their participation is very useful for range managers to plan and provide solutions for solving problems. This study aims at comparing barriers of participating from rangers and experts point of view in Lar moor rangelands, Tehran, Iran. In this research, […]
The main objective of an ecosystem sustainable management is to preserve its capacity to respond and adapt to current disturbances and/or future changes, and maintain the provision of environmental goods and services. Two very important properties linked to this objective are the ecosystem resilience and resistance to disturbance factors. The objective of this paper is […]
Plant biomass is an important factor for determining arid and semi-arid rangelands capacity. Due to the lack of proper and annual sampling of rangelands, there are no suitable data to determine biomass, range condition and proper range management operations. Plant biomass is one of the measurable attributes that can be assessed in rangeland studies. Since […]
Erosion is one of the important social-economic problems in Iranian catchments that have been posed by surface water vastness and runoff production. So, the study of water resources, soil erosion and effective factors is of high importance. Gully erosion also extends in many parts of Iran and its study particularly in viewpoint of sediment yield […]
In recent years, studying the dietary preferences and livestock grazing behavior has attracted lots of attention due to manage and improve the efficiency of rangelands. So, in this study the foraging behavior and diet selection of Tali goat was investigated in the Chabahar Rangeland during 2008-2010. Data were collected and analyzed for speeds of livestock, […]
In order to study of ecological and phenological traits of Ferulago angulata as an important medicinal plant, this research was conducted in Hezar Mountains and Bondareh Henza in Kerman province, Iran. Random samples of this plant were taken and their vegetation habitat conditions and their growth characteristics including height of collar leaves, height of flower […]
This research was conducted to investigate the factors contributing to the failure in the forestry and rangeland by-product cooperative companies in Lorestan province, Iran. A descriptive-correlative research design was used. The statistical populations were 1100 people divided into two groups of experts from natural resource agency in Lorestan province and members of cooperative companies. The […]
Vetiver grass (Vetiveria zizanioides) is known to be survived under the diverse soil and water conditions. In order to study the effects of salinity stress on the seedling growth of the desired species, a completely randomized design was conducted with 3 replications. Seeds were sown in the salty-soil plots in the greenhouse. Salinity levels were […]
Soil organic matter has positive consequences eht rof quality and productivity of soil and also environment, agricultural and biological sustainability and conservation of biodiversity and soil. Organic matter plays an important role in the physical and chemical processes of soil and thus, it is of a great effect on the spectral characteristics of soil. This […]
