Integrated Noxious Weed Management After Wildfires, Natural Resources Conservation Service Jan 2001

Integrated Noxious Weed Management After Wildfires, Natural Resources Conservation Service

All U.S. Government Documents (Utah Regional Depository)

The ecosystems of the west are adapted to a long history of wildland fires that varied in frequency and severity. Over the last 100 years or more, though, fire suppression efforts, human settlement patterns and other land use practices have changed the composition and structure of the forests and grasslands of the West. Where once we typically had periodic low-intensity fires of low severity, we now experience damaging fires that can be both intense and severe. Severe fires can substantially affect the environment. Lack of vegetation on burned hillsides increases the likelihood of flooding and soil erosion from rain and …

A Management-Oriented Classification Of Pinyon-Juniper Woodlands Of The Great Basin, Neil E. West, Robin J. Tausch, Paul T. Tueller, United States Department Of Agriculture, Forest Service, Rocky Mountain Research Station

All U.S. Government Documents (Utah Regional Depository)

Pinyon-juniper woodlands occupy about 18 percent (7.1 million ha, 17.6 million acres) of the land area of the Great Basin (Tueller and others 1979). The associated tree species are found over a wide range of environmental conditions extending from communities representative of the upper fringes of the Mohave Desert to communities found at the lower fringes of high mountain forests. Over this spatial and elevational range, communities associated with pinyon-juniper woodlands are highly variable, with complex distribution and compositional patterns. This variability is due to climatic changes occurring over the last 10,000 years and to variation in current environmental conditions …

Department Of Energy Programmatic Spent Nuclear Fuel Management And Idaho National Engineering Laboratory Environmental Restoration And Waste Management Programs Final Environmental Impact Statement, Volume 1, Appendix D, Part B, United States Department Of Energy

All U.S. Government Documents (Utah Regional Depository)

The methods used to perform the analyses in the environmental impact statement have been refined in the time since the environmental assessment was prepared. This occurred partly because of the larger number of naval spent nuclear fuel assemblies analyzed and the wider scope of sites and methods of storage to be evaluated, and partly because additional time was available to implement the refinements. In addition to refinements in the methods for performing the calculations, some minor changes in the calculational models were made in order to establish a high degree of consistency with the analytical methods used for the other …

This appendix addresses the interim storage of spent nuclear fuel (SNF) at two U.S. Department of Energy sites, the Nevada Test Site (NTS) and the Oak Ridge Reservation (ORR). These sites are being considered to provide a reasonable range of alternative settings at which future SNF management activities could be conducted. These locations are not currently involved in management of large quantities of SNF; NTS has none, and ORR has only small quantities. But NTS and ORR do offer experience and infrastructure for the handling, processing and storage of radioactive materials, and they do exemplify a broad spectrum of environmental …
