Polycyclic Aromatic Hydrocarbon (Pah) Contamination In Urban Soils: Testing And Management, Melissa Chilinski, Paul Grossl, Melanie Stock

All Current Publications

Polycyclic aromatic hydrocarbons (PAHs) are a large class of chemicals and common environmental pollutants. Understanding which PAHs and soil test levels may impact human health is an important aspect of gardening and micro-farming, particularly in urban environments that are at increased risk of soil contamination. Land use histories, such as sites associated with vehicle and industrial emissions, burning, and dumping, can elevate concentrations of PAHs in soils. This fact sheet provides instructions on assessing your site for PAHs that may present health risks to humans, testing the soil, and first steps for interpretation and management.

Management Innovations For Resilient Public Rangelands: Adoption Constraints And Considerations For Interagency Diffusion, Gwendŵr R. Meredith, Mark W. Brunson, Stuart P. Hardegree

Environment and Society Faculty Publications

Maintaining healthy rangeland ecosystems requires adaptive co-management at the landscape scale. Because the majority of western rangelands are publicly owned, it is critical that federal land management agencies work together in generating and sharing information. Promotion and communication of rangeland management innovations among agencies is one means of sharing information. Two rangeland management innovations, the Weather-Centric Restoration Tool and Interpreting Indicators of Rangeland Health, were studied in order to better understand agency adoption decisions and barriers to diffusion of the innovations across agencies. Using a mixed qualitative methodology, we interviewed land managers across the floristic Great Basin and in southeastern …

Modelling Eurasian Beaver Foraging Habitat And Dam Suitability, For Predicting The Location And Number Of Dams Throughout Catchments In Great Britain, Hugh A. Graham, Alan Puttock, William W. Macfarlane, Joseph Michael Wheaton, Jordan T. Gilbert, Róisín Campbell-Palmer, Mark Elliott, Martin J. Gaywood, Karen Anderson, Richard E. Brazier

Watershed Sciences Faculty Publications

Eurasian beaver (Castor fiber) populations are expanding across Europe. Depending on location, beaver dams bring multiple benefits and/or require management. Using nationally available data, we developed: a Beaver Forage Index (BFI), identifying beaver foraging habitat, and a Beaver Dam Capacity (BDC) model, classifying suitability of river reaches for dam construction, to estimate location and number of dams at catchment scales. Models were executed across three catchments, in Great Britain (GB), containing beaver. An area of 6747 km² was analysed for BFI and 16,739 km of stream for BDC. Field surveys identified 258 km of channel containing beaver …

The HMAs included in this complex are Lost Creek, Stewart Creek, Green Mountain, Crooks Mountain and Antelope Hills (See Area Map, Appendix 2). The EA is a site-specific analysis of potential impacts that could result with the implementation of a …

Evaluating The Effectiveness Of Grassbed Treatments As Habitat For Juvenile Black Bass In A Drawdown Reservoir, D. R. Ratcliff, Wayne A. Wurtsbaugh, J. Zustak

Watershed Sciences Faculty Publications

Many reservoirs in arid regions experience highly variable water levels caused by seasonal inflow fluctuations and designated outflow requirements. At Shasta Lake, California, managers plant cereal-grain grassbeds on exposed drawdown shorelines to increase juvenile fish habitat, localize productivity, and increase invertebrate fish prey. To determine the efficacy of these plantings, the abundance of juvenile black basses Micropterus spp. (20–55 mm standard length) and the amount of periphyton and macroinvertebrate prey were compared among three treatment types: (1) planted grassbeds of cereal barley Hordeum vulgare; (2) artificial rope grassbeds, which eliminated physical deterioration and nutrient release; and (3) nonplanted control sites …

Salt Creek is the largest drainage in the Needles district of Canyonlands National Park. The creek supports one of the most important riparian ecosystems in the park. It is also the heart of the Salt Creek National Register Archeological District, the area with the highest recorded density of archeological sites in the park. A tributary canyon contains the spectacular Angel Arch, a well-known geologic formation that for many years has been a destination point for park visitors. In 1998 the U.S. District Court for the State of Utah ruled, in a lawsuit filed by the Southern Utah Wilderness Alliance, that …

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 …

Environmental Assessment For Wild Horse Gathering Outside Wild Horse Herd Management Areas, United States Department Of The Interior, Bureau Of Land Management

Environmental Assessments (WY)

The Bureau of Land Management is responsible for the welfare of wild horses. The wild horse program is under constant scrutiny by the public for actions concerning wild horse management and gathering. Within the Rawlins field office (RFO) there is a substantial acreage of "checkerboard" lands. Approximately 50 percent of these lands are BLM-administered public lands and 50 percent are private lands controlled by many private entities. The northern portition of the gather area contains this type of land pattern.

Management Alternatives And Environmental Assessment, Mormon Row Historic District Grand Teton National Park, Wyoming, United States, Department Of The Interior, National Park Service

Environmental Assessments (WY)

Few people visiting Mormon Row today realize that the six remaining homesteads constitute about a fifth of those that once defined the Mormon Row community. Time and the harsh climate have taken an extreme toll. Most structures that remain stand abandoned and in need of repair. The farms are not interpreted and most visitors probably do not even know that the historic area is within the boundaries of Grand Teton National Park. Nevertheless, the area receives a light but steady amount of visitation. Visitors remark about inadequate parking, lack of interpretation, the deteriorated condition of many of the historic structures, …

Management For The Red Gulch Dinosaur Tracksite Big Horn County, Wyoming, Environmental Assessment, United States Department Of The Interior, Bureau Of Land Management

Environmental Assessments (WY)

A review of existing land-use planning decisions is being conducted to evaluate how to best manage public lands, resources, educational opportunities, and other values associated with the recent discovery of dinosaur tracks on BLM-administered public lands near Shell, Wyoming. The tracks were not addressed in the Washakie Resource Management Plan (RMP) which was completed in 1988. A review of BLM's planning decisions for the discovery area is needed to evaluate the adequacy of existing management prescriptions for the protection of the tracks and related values.
