Article history: Received 14 November 2005 Received in revised form 24 April 2006 Accepted 26 May 2006 Available online 31 July 2006 Classic rangeland theory advocates stocking rangelands at relatively lowand constant levels. This theory has been labelled inappropriate for savanna rangelands, because savannas are strongly influenced by stochastic processes. Opportunistic strategies that force a...

A study was conducted to determine foraging efficiency of cattle, mule deer, and elk in response to previous grazing by elk and cattle. Four enclosures, in previously logged mixed conifer (Abies grandis) rangelands were chosen, and within each enclosure, three 0.75 ha pastures were either: 1) ungrazed, 2) grazed by cattle, or 3) grazed by elk in mid-June and mid-July to remove approximately 40%...

State-led policies of pastoralist removal from protected areas, following the fortress model biodiversity conservation, have been a common practice across parts Asia and Africa. In Himalayan region South Asia, restrictive access communities areas compensated by state through “eco”-tourism. this paper, we critique current conservation adopted in Indian Himalaya, which focuses on conservation-pas...

Based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. This research was carried out in a part ofhighland mountainous rangeland of Mount Alborz Range in Iran. Diversity and richnesswere assessed as an ecosystem health indicator. The study area was locate...

The San Francisco Bay Area in California, USA is a highly heterogeneous region in climate, topography, and habitats, as well as in its political and economic interests. Successful conservation strategies must consider various current and future competing demands for the land, and should pay special attention to livestock grazing, the dominant non-urban land-use. The main objective of this study...
