Identifying major drivers of deforestation and forest degradation has been an important task at the present context of Reducing Emissions from Deforestation and Forest Degradation “REDD+”. At present, many bilateral and multilateral projects are carrying out pilot activities for the REDD+ in developing countries and many Asian countries are being engaged in this process. Asian countries namely ...
Silvopasture practices are being advocated as a means of maintaining pine forest acreage in the southeast United States; however, scientific data on the design and management for optimum tree growth are lacking. Studies were conducted near Booneville AR to determine the effects of weed control, irrigation, soil fertilization and protection from cattle grazing on the establishment of loblolly pi...
To modeling of Suitability Iranian Oak site to establish coppice regenerations, chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, southern Zagros forest, and southwest Iranian state was selected. To modeling Suitability Iranian Oak used the physiographic element, soil depth, climatology and distance from village selected. To this study used the raster formats by pixel...
World-wide population declines have sharpened concern for amphibian conservation on working landscapes. Across the Sierra Nevada's national forest lands, where almost half of native amphibian species are considered at risk, permitted livestock grazing is a notably controversial agricultural activity. Cattle (Bos taurus) grazing is thought to degrade the quality, and thus reduce occupancy, of me...
introduction ownership is an important element for sustainability development in natural resource management. rangelands vegetations are important factor for produce in traditional herding therefore recognition of different utilization methods and management of this vegetation resource production for animal grazing and rangelands condition is very important. so this research carried out in 2009...
Drought and grazing rangelands play an important role in changing the structure of vegetation and losing the biodiversity of natural ecosystems. In this research, in order to determine the effects of drought and livestock grazing on the vegetation structure of rangelands located in the Nakhab Forest of South Khorasan Province, species abundance, biodiversity, and range condition and trend were ...
Daegwallyeong is a mountain pass at an altitude of 832 m, which has been designated conservation area because its essential role in Korea’s forest ecosystem. Simultaneously, this considered suitable place for grazing due to the cool temperature during summer. Some areas have converted grassland livestock feeding, and scale continued increasing. Although more ecofriendly than industrialized faci...
Rangelands in Saudi Arabia extend over more than 175 m.ha. (about 75% of country land area) while woodland forests occupy only 2.7 m.ha. and are limited to the south western highlands. The diversity in landscape has been reflected in terrestrial plant species diversity. Range vegetation as well as forest understory vegetation has long history of grazing by livestock and wildlife herbivores. In ...
After a brief description of the framework of the model developed to simulate vegetation dynamics, fire propagation and agents' behaviour, the role-playing game rules are presented and related to the different points they are supposed to deal with: climatic hazard, animal grazing, forest management, grazing duty, financial support. The results of several sets of game sessions are analysed accor...
