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...

is when per capita production and consumption grow. This may occur when more hours are spent working; but more important, for the long-term, is new technology, which leads to higher rates of extraction and/or more effi cient use of resources. For most nations, economic growth refl ects a concurrent increase in population and per capita production and consumption, all facilitated by the developm...

Calibrated predictive relationships obtained from simple and multiple regression of thematic mapper or broad-band (BB) and 1.4 nm interval or narrow-band (NB) spectral data were evaluated for quantifying 11 rangeland components (including total vegetation, forb, grass, shrub, litter, and bare soil) and distinguishing among 6 long-term grazing treatments of sagebrush steppe. In general, all 4 da...

One hundred twenty crossbred steers (450 lb, +/37 lb) were stratified by weight and randomly assigned to one of two feeding blocks. The cattle grazed dormant rangeland for 56 days from October 12 through December 7. Each block was supplemented three times a week with the equivalent of 7 days of dried corn distiller’s grains (DDG) at 0, 0.25, 0.50, or 0.75% body weight (BW)/d on a dry matter bas...

Land degradation of alpine rangeland in Dachigam National Park, Northern India, was evaluated in this study using MODerate resolution Imaging Spectroradiometer (MODIS) land products. The park has been used by a variety of livestock holders. With increasing numbers of livestock, the managers and users of the park are apprehensive about degradation of the grazing land. However, owing to weak infr...

Rangeland monitoring aims to determine whether grazing management strategies meet the goals of sustainable resource utilization. The development requires an understanding manner in which animals utilize available vegetation. In this study, we made use livestock tracking, situ observations and Sentinel-2 imagery make rangeland scale vegetation conditions a semi-arid environment, better understan...

Climate finance investments and international policy are driving new community-based projects incorporating payments for ecosystem services (PES) to simultaneously store carbon and generate livelihood benefits. Most community-based PES (CB-PES) research focuses on forest areas. Rangelands, which store globally significant quantities of carbon and support many of the world's poor, have seen litt...

The aim of this project was to develop a conceptual framework and analysis tools to assess the adaptive capacity of community-based collaborative groups (CBCs), to test these tools by applying them to three rangeland collaboratives, and to identify factors that contribute to the adaptive capacity of CBCs. We developed a conceptual framework for assessing the adaptive capacity of CBCs and used t...

Herbivory and fire are natural interacting forces contributing to the maintenance of rangeland ecosystems. Wildfires in the sagebrush dominated ecosystems of the Great Basin are becoming larger and more frequent, and may dramatically alter plant communities and habitat. This synthesis describes what is currently known about the cumulative impacts of historic livestock grazing patterns and short...
