This study was conducted in Alzzazah area which lies approximately 25 km East of El-Dmazein city, the capital of the Blue Nile State, Sudan. This study was carried out at the end of the autumn 2015. The aim of the study was to evaluate the impacts of continuous grazing on the rangeland of the study area. To determine this effect, two range sites were selected to represent the rangeland in the s...
assessment process of vegetation cover by remote-sensing images should be based on understanding of the vegetation indices. vegetation indices are widely used for assessing and monitoring ecological variables such as vegetation cover, above-ground biomass and leaf area index. the aim of the present research was to study of the aster data capabilities to estimate the vegetation cover percentage ...
The Grasshopper Integrated Pest Management Project (GHIPM) WDS a S15 million projccllhat lasted from 1986 La 1994 to identify, develop, and implement rangeland grasshopper management tactics within the Framework of Integrated Pest Management (lPI\'I) in the western United Stales. Computer simulation has been used La fulfill many original objectives for GHIPM and help bridge the gap between theo...
Water plays a critical role in beef cattle production. Current methods used to estimate the blue water footprint of are largely based on generic values that do not make provision for different production systems within regions. Total cycle measurements should therefore be considered accurately assess grazing natural rangeland. The aim study was measure intake extensive Bonsmara Marikana Thornve...
since last decades, there has been a growing interest in the human/social dimensions of natural resources governance especially the structure of social networks in achieving to successful co-management of natural resources. network analysis as a suitable tool in optimum planning of the “network management” of rangeland in regional scale, can improve inter-organizational decision-making and coor...
Domestic goats are raised for meat, milk and hair production, in herds for rangeland weed control, and as pack animals. Domestic sheep, goats and wild bighorn sheep are all susceptible to a multifactorial pneumonia. We sampled 43 herd goats from 7 herds and 48 pack goats from 11 herds for viral and bacterial serology, parasitology, and Pasteurellaceae microbiology. The goats in this study were ...
We examined changes in rangeland health in the semi-arid woodlands of eastern Australia at fixed sites between 1989 and 1999. Over the 11-year period there were significant declines in the quality of the vegetation, and changes in plant species were driven largely by seasonality, and to a lesser extent, amount of rainfall. Three indices of rangelands health (composition, function and stability)...
