Many species of wildlife depend on riparian habitats for various life-history functions (e.g., breeding, foraging, overwintering). Although this unique habitat is critical for many species, delineations of riparian zones and buffers for various taxa are lacking. Typically when buffer zones are determined to mitigate edge effects, they are based on criteria that protect aquatic resources alone a...

Habitat suitability index (HSI) models are traditionally used to evaluate habitat quality for wildlife at a local scale. Rarely have such models incorporated spatial relationships of habitat components. We introduce Landscape HSImodels, a new Microsoft Windowst (Microsoft, Redmond, WA)–based program that incorporates local habitat as well as landscape-scale attributes to evaluate habitats for 2...

Dead wood is an important component of the forest for many species. In many locations, however, the presence of dead wood has declined, and there is a need to make what is left more suitable for the myriad of creatures dependent on this material. In this paper, I will summarize the value of dead wood for these species and describe methods for improving the dead wood component of the forest to m...

Barbed and woven wire fences, common structures across western North America, act as impediments to wildlife movements. In particular, fencing influences pronghorn (Antilocapra americana) daily and seasonal movements, as well as modifying habitat selection. Because of fencing's impacts to pronghorn and other wildlife, it is a potentially important factor in both wildlife movement and habitat se...

Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limi...

one of the most struggling issues for conservationists and wildlife managers is the climate change. this can be the necessity to develop climate condition indicators. due to the limited movements and special habitat conditions, pikas can be considered as reliable climate indicators. in this study, the most important climatic factors defining the distribution of this species were investigated to...
