Livestock grazing potentially has substantial influence on fuel characteristics in rangelands around the globe. However, information quantifying the impacts of grazing on rangeland fuel characteristics is limited, and the effects of grazing on fuels are important because fuel characteristics are one of the primary factors determining risk, severity, continuity, and size of wildfires. We investi...
Long-term studies can broaden our ecological understanding and are particularly important when examining contingent effects that involve changes to dominance by long-lived species. Such a change occurred during the last century in Southwestern (USA) ponderosa pine (Pinus ponderosa) forests. We used five livestock grazing exclosures established in 1912 to quantify vegetation structure in 1941 an...
Awareness of rangelands plants palatability is required for estimating available forage to animals in all plant communities. In this research recording method was used to determine species palatability in rangelands of Deh- Shiekh in Kohkiloyeh and Boyer Ahmad Province. Three perennial species including Gundelia tournefortii, Bromus tomentellus, Hordeum bulbosum and two annual species of Agelup...
Frequent and intense defoliation of grasses has been associated with the evolution of “grazing morphotypes” that exhibit a variety of vegetative traits correlated with improved grazing resistance. While recovery from a seed bank is not considered an important grazing resistance mechanism, relatively little is actually known regarding seed (caryopsis) production in grazing morphotypes of caespit...
1. Wetlands as Grazing Grounds 1.1. Wetlands and Traditional Seasonal Grazing: La Puna, Argentina–Bolivia–Chile– Peru 2. Grazing in Wetlands: Should this Threat be Prohibited? 2.1. Maintaining Biodiversity through Semi-Extensive Grazing: Palo Verde National Park, Costa Rica 3. Integrated Grazing Management in Wetlands: New Approaches 3.1.

Nigeria is one of the most malnourished and hunger ridden in the league of developing countries; according to reports of Food and Agricultural Organization (FAO) of United Nations estimated daily animal protein intake for developing countries averaged at 4.5 g/head/day at the beginning of this century which has hardly risen to 10 g/head/day into the second decade of the century in Nigeria. This...
Executive Summary Livestock in Ethiopia has an important economic, functional, and cultural significance. Various functions of livestock include dairy production, meat production, draught labor and transportation. Economically, livestock production accounts for nearly 80% of farmer income 1 in the country. In addition, livestock serves as a “savings account” or a way of building assets. Cultura...
Growing pearl millet and cowpea in combination with raising ruminant livestock is widely practised in the Sahel. In this farming system, livestock feeding depends mostly on rangeland, fallows and cropland grazing. Nutritional constraints to grazing ruminants stem primarily from feed scarcity and seasonal fluctuations in feed supply associated with low rainfall and poor soil fertility. Low feed ...
in recent years, studying the dietary preferences and livestock grazing behaviorhas attracted lots of attention due to manage and improve the efficiency of rangelands. so,in this study the foraging behavior and diet selection of tali goat was investigated in thechabahar rangeland during 2008-2010. data were collected and analyzed for speeds oflivestock, covered distance, time of grazing, restin...
Prescribed fires are used to manipulate and manage rangelands, but effective monitoring techniques are needed to ensure that management goals and objectives are being met. The application of an effective fire program on rangelands is not a simple task. Overgrazing by livestock since the early development of the livestock industry has altered the vegetative complex on most rangelands with an inc...
