one of the key factors in managing a rangeland is to determine the relative preference of its major plant species by thegrazing livestock. preference value of each plant species is affected by plant type, companion plants, availability byanimals, phenological stage, climate condition, and the livestock species. we investigated the grazing behaviour of anative goat (garizi) in the steppe rangela...

Miombo woodlands sustainability in east and south-central Africa is threatened by human activities, including overgrazing. This study investigated seasonal variations rangeland condition three grazed areas miombo eastern Tanzania. Transect lines were established across the grazing areas, sampling points identified marked at every 10% of length transect line. Sampling categorised different dista...

CARMA (CAse-based Range Management Adviser) is a system that integrates case-based reasoning with model-based reasoning for rangeland pest management. CARMA’s predictions of rangeland forage loss by grasshoppers were compared to predictions by 15 expert entomologists using either global or case-specific adaptation weights. Under both conditions, CARMA’s predictions were more accurate than CARMA...

In Mexico, the concepts of rangeland site and condition are not well known. For this reason, most rangelands private ranches on high plateau San Luis Potosí Zacatecas undergoing a process severe generalized deterioration. The purpose study was to survey characterize multi-branched sites three beef cattle Potosí-Zacatecas High Plateau, as assess their using quantitative ecological method complem...

overgrazing, via harvesting of forage species and decrease the other herbs, is of progressive factors in biodiversity destroying. in order to investigate the animal grazing impacts on changing of plant structure and diversity, we selected the comparison between this effect with exclosure area, and proving of the excluded area effects on plant diversity; two sites of kojour rangeland, mazandran ...

this research was conducted to recognize sibak-sardab watershed rangeland potentials, evaluate and determine of suitability classes for sheep grazing. in this research, we used the proposed method of fao (1992) and for information layers crossing used in geographical information system (gis). in this research, sensitivity to erosion, water resources and forage production are three basic compone...
