In the western Algerian steppe, public authorities have carried out actions aimed at rural development (agricultural programs) and combating desertification (grazing reserves) to counter significant rapid loss of vegetation cover pastures by overgrazing, consequent impacts on local livelihoods. Rogassa area, these impacted land tenure ancestral collective way use access. These changes caused tr...

Drylands occupy 6.15 billion hectares (Bha) or 47.2% of the world's land area. Of this, 3.5 to 4.0 Bha (57%-65%) are either desertified or prone to desertification. Despite the low soil organic carbon (SOC) concentration, total SOC pool of soils of the drylands is 241 Pg (1 Pg = petagram = 10(15)g = 1 billion metric ton) or 15.5% of the world's total of 1550 Pg to 1-meter depth. Desertification...

In the pine forests of Mexico, disturbances are primarily due to cattle, horses, goat, and sheep grazing, particularly in communal grazing lands. The most evident low tree recruitment, invasive shrubs establishment, species composition changes, invasion weeds dispersed mainly by livestock. Sierra de Zapalinamé is a mountain range natural protected area northeast Mexico. We conducted current stu...

Soil is the fundamental component of each terrestrial ecosystem, so consequences land management regime on soil health and productivity should be evaluated. To this end, long term effects livestock grazing were studied in three systems north-eastern Iran, comprising unlimited grazing, managed a rangeland where was prohibited. First, properties including pH, EC, bulk density contents phosphorus,...

The species composition of grazing lands can be influenced by livestock and grazing pressure. A study on manure seed bank was conducted in Ghinchi highland Research Site in Ethiopia between 1995 and 1997. The data on species composition and life-form of the plants germinating in pots receiving air dried manure were compared with species composition of experimental plots in natural grassland sub...

A move by the US government to preserve more public lands as wilderness has been welcomed by environmentalists but has angered ranchers, sportsmen and energy companies that fear access to land will be reduced. The new policy, initiated at the end of last year, directs the Bureau of Land Management to survey its vast holdings from Alaska to Arizona in search of unspoilt wildlife areas. The agenc...

Efforts to curb elephant poaching have focused on reducing demand, confiscating ivory and boosting security patrols in elephant range. Where land is under multiple uses and ownership, determining the local poaching dynamics is important for identifying successful conservation models. Using 2,403 verified elephant, Loxodonta africana, mortality records collected from 2002 to 2012 and the results...

Natural grassland productivity, which is based on an individual plant's aboveground biomass (AB) and its interaction with herbivores, can obviously affect terrestrial ecosystem services and the grassland's agricultural production. As plant traits have been linked to both AB and ecosystem success, they may provide a useful approach to understand the changes in individual plants and grassland pro...
