This report delineates reasonable objectives, based upon the best scientific and commercial data available at the time of its release, for the conservation and survival of greater sage-grouse. Individual team members contributed by providing technical information and data, participating in critical discussions, providing critical reviews and edits, or authoring sections...
What do you say when you have only a minute to explain to a municipal official why keeping track of the number of bird species found in a park may help make decisions about park management? Talk of significant differences among treatments or testing theory will likely meet with glazed...
North American bird populations have declined throughout the past half century. The majority of studies quantifying these declines have focused on spring and summer breeding birds; not the season of scarcity, winter. We re-surveyed 7 large study plots in Douglas fir forests initially surveyed in winter during the late 1960s...

Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...
Rainfall runoff erosivity (R) is one key climate factor that controls water erosion. Quantifying the effects of climate change–induced erosivity change is important for identifying critical regions prone to soil erosion under a changing environment. In this study we first evaluate the changes of R from 1970 to 2090 across...
