Grazing on natural rangelands, which are areas dominated by native vegetation that are used for livestock grazing, can achieve desired vegetation outcomes, preserve native habitat, and economically benefit multiple stakeholders. It is a powerful tool that can be manipulated to reduce wildlife declines and benefit ecosystems. However, the benefits of conservation grazing systems on many wildlife...

In grazed habitats is a tradeoff between competition (decreases with the grazing intensity) and disturbance (increases). This may give tradeoffs between plant life stages. The seed production can be assumed to decrease at high disturbance intensities because of herbivory of reproductive organs, but also at high levels of competition (low grazing intensity) because of resource limitation. The es...

To reach the desirable ecosystem management, determining the animal dietselection, which is one of the components of rangeland ecosystem, is important. Therefore, inorder to determine the grazing behavior and diet selection of sheep and goat, the uplandrangeland of northern part of Alborz was selected. In this study, the first weeks of July andAugust of 2009 were chosen for the grazing period o...

Soil degradation caused by overgrazing is a worldwide problem. The degradation of an overutilized area occurs mainly where animals prefer to spend extra time because of the attractants that are around gateways, water sources, along fences or farm buildings. High grazing pressure decreases plant density which results in changes of the botanical composition of a pasture. The effect that grazing h...

Intensification of fires and grazing by large herbivores has caused population declines in small vertebrates in many ecosystems worldwide. Impacts are rarely direct, and usually appear driven via indirect pathways, such as changes to predator-prey dynamics. Fire events and grazing may improve habitat and/or hunting success for the predators of small mammals, however, such impacts have not been ...

Chaparral lands of central Arizona are important for water production. They are also used as grazing lands for livestock and as habitat for wildlife. An understanding of the relation of grazing to runoff and erosion is thus essential to the development of management systems for sustained high yields. This paper reports the effects of grazing on runoff and erosion as determined on four experimen...

overgrazing and inappropriate use of taleghan rangelands has led to poor and very poor condition for almost all vegetation types. taking the importance of rangelands in forage production and other benefits into consideration, management of these rangelands and improving their condition seems essential. the present research was conducted using data integration of vegetation, condition, slope, so...

Measuring the impact of livestock grazing on grassland above-ground net primary production (ANPP) is essential for grass yield estimation and pasture management. However, since there is a lack of accurate and repeatable techniques to obtain the details of grazing locations and stocking rates at the regional scale, it is an extremely challenging task to study the influence of regional grazing on...

abstract. rangelands are mainly used for grazing the livestock in iran, it is essential to specify grazing suitability of rangelands in each region of country, so that it may improve the management policies and approaches for planning and designing current and future plans. the aim of this research was to determine the rangeland suitability for sheep grazing in the watershed of sadegh abad, ker...
