form the basis fo r experience based setting management o f outdoor recreation areas. To test the assumptions a sample o f wilderness users was surveyed and divided into experience groups based on differences in the specific experiences they desire. These experience groups were then tested fo r differences in their activity and setting preferences. The study was conducted at the Bridget Wildern...
Monitoring of Wilderness lakes for potential acidification requires information on lake sensitivity to acidification. Catchment properties can be used to estimate the acid neutralizing capacity (ANC) of lakes. Conceptual and general linear models were developed to predict the ANC of lakes in high-elevation (> or = 2170 m) Wilderness Areas in California's Sierra Nevada mountains. Catchment-to-la...
Non-native plant invasions can change communities and ecosystems by altering the structure and composition of native vegetation. Changes in native plant communities caused by non-native plants can influence native wildlife species in diverse ways, but the outcomes and underlying mechanisms are poorly understood. Here, we review and synthesize current information for the Intermountain West of th...
appearing in Cronon’s oft-cited collection Uncommon Ground were focused more on coming to terms with the consequences of the cultural mediation of our knowledge of nature and models of ecological change in postwar environmentalism, Cronon’s own dismantling of the meanings and images associated with the American wilderness idea suggested that the earlier conservation movement was also implicated...
Several of the most important conservation prioritization approaches select markedly different areas at global and regional scales. They are designed to maximize a certain biodiversity dimension such as coverage of species in the case of hotspots and complementarity, or composite properties of ecosystems in the case of wilderness. Most comparisons between approaches have ignored the multidimens...

A systematic review was carried out to prepare a checklist of the mammalian species northeastern India. The region is located between two prominent biodiversity hotspots, Himalaya and Indo-Burma. Though it only 8% country, supports almost half country’s total wild flora fauna. Ongoing developmental activities such as construction roads, electrification, mining in around wildlife habitats have t...
