An Approach for Analysis of Integrated Components on Available Forage in Semi-Arid Rangelands of Iran

This study describes the components of available forage in Vahregan watershed, Central Iran and highlight issues relating to forage endowment and environmental dynamics. In this study, proper use factor and palatability models and their components use to develop the model of available forage and measure it. The components climatic, topography, land systems, vegetation, land use and grass and sh...

Assessing Impact of Anthropogenic Disturbances on Forage Production in Arid and Semiarid Rangelands

Forage is one of the main products of rangeland ecosystems, which is threatened by different anthropogenic disturbances. This study was conducted to assess the impact of urbanization, rural development, agriculture extension, road construction and industry on forage production in an arid and semiarid rangeland using InVEST habitat quality model in spring 2018. In 14 rangeland types, thirty 2×1m...

Soil-Vegetation Relationships in Arid Rangelands (Case Study: Nodushan Rangelands of Yazd, Iran)

The objective of this research was to identify the vegetation-soil relationships in Nodushan arid rangelands of Yazd. 5 sites were selected for measuring the cover of plant species and soil attributes. Soil samples were taken in 0-10 and 10-80 cm layers. The species studied were Salsola tomentosa, Salsola arbuscula, Peganum harmala, Zygophylum eurypterum and Eurotia ceratoides. Canonical corres...

Mapping of forage Production in Poor Rangelands Haftkel Rangelands Using Sentile-2 Images

Background and objectives: Determining the exact amount of forage production can be of great help to rangeland managers and relevant specialists in determining proper stocking rate. With implementing proper sampling design, remote sensing data could be used to accurately estimate forage production due to the extent of rangelands areas, cost, time spent and other problems in data gathering from ...
