The expansion of native, woody plants is a global phenomenon with characteristics and effects that are often indistinguishable from exotic invasions. These expansions have largely been driven by altered fire regimes and favorable climatic conditions. In the Great Basin of western North America, expansion of conifers such as western juniper...
Understanding the effects of disturbance and restoration on a species’ habitat is essential for understanding the demographic rates and population trends observed in a species. Sufficient habitat provides the space and resources required for survival and successful reproduction, such as food availability, access to water, protection from predators, protection from...
The rapid expansion of western juniper into neighboring plant communities during the past 130 years has caused considerable concern because of increased soil erosion, reduced stream
flows; reduced forage production; altered wildlife habitat; changes in plant community composition, structure, and biodiversity; and the replacement of mesic and semi-arid plant communities...
The expansion of pion-juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel...
Access to BLM fuels reduction areas in the Klamath Falls Resource Area is limited to few roads in good travel condition. Many of the access roads, both system and non-system, are in poor condition due to rocky and/or seasonally wet ground conditions, requiring seasonal travel restrictions to prevent high impacts...
All streams in Oregon that are inhabited by salmon and trout have a statemandated
water temperature standard. However, temperatures of many streams,
especially during summer months, exceed the seven-day average maximum
temperature parameter (200 C for redband trout inhabited streams) accepted by the
Oregon Department of Environmental Quality. To date,...
