This workshop is part of a broader research project aimed at better understanding how communities can engage in the process of wind energy development. The research is funded through a National Science Foundation grant (#SES 0724672) to Roopali Phadke at Macalester College. This report was prepared by a research team from Macalester College. Throughout the day of the workshop, the research team collected demographic data about participants, gauged their familiarity with wind energy, and elicited their perceptions about landscape impacts. This was done through the use of interactive keypad polling, photographic analysis within focus groups, open-ended writing exercises and a final evaluation. The data were brought...
Geothermal energy, carbon sequestration, and enhanced oil and gas recovery have a clear role in U.S. energy policy, both in securing cost-effective energy and reducing atmospheric CO2 accumulations. Recent publicity surrounding induced seismicity at several geothermal and oil and gas sites points out the need to develop improved standards and practices to avoid issues that may unduly inhibit or stop the above technologies from fulfilling their full potential. It is critical that policy makers and the general community be assured that EGS, CO2 sequestration, enhanced oil/gas recovery, and other technologies relying on fluid injections, will be designed to reduce induced seismicity to an acceptable level, and be developed...

Synopsis: This study analyzed the effects of vegetation change on hydrological fluctuations in the Columbia River basin over the last century using two land cover scenarios. The first scenario was a reconstruction of historical land cover vegetation, c. 1900. The second scenario was more recent land cover as estimated from remote sensing data for 1990. The results show that, hydrologically, the most important vegetation-related change has been a general tendency towards decreased vegetation maturity in the forested areas of the basin. This general trend represents a balance between the effects of logging and fire suppression. In those areas where forest maturity has been reduced as a result of logging, wintertime...

USDA-ARS researchers have put together high resolution ARC-GIS layers for intertidal bathymetry and distance to mouth as well as eelgrass, burrowing shrimp and oyster aquaculture habitats in Willapa Bay, Washington for this project. We await results of bathtub modeling exercise and climate scenario projections to integrate and validate models to examine effects of SLR and temperature and salinity changes on these habitats and engineering species. We have also assembled a historical layer representing native oyster (Ostrea lurida) habitat in Willapa Bay and are in the process of assembling data for oyster aquaculture and potential native oyster habitats in Coos Bay, Yaquina Bay, and Netarts estuaries in Oregon.
Long-term, non-contact river velocity measurements have been made using a UHF RiverSonde system for several months at each of two locations having quite different flow characteristics. Observations were made on the Cowlitz River at Castle Rock, Washington from October 2003 to June 2004, where the unidirectional flow of the river ranged from about 1.0 to 3.5 m/s. The radar velocity was highly correlated with the stage height which was continually measured by the U. S. Geological Survey. The profile of the along-channel velocity across the water channel also compared favorably with in-situ measurements performed by the Survey. The RiverSonde was moved to Threemile Slough, in central California, in September 2004 and...
The Habitat Evaluation Procedures (HEP) were used to evaluate pre- and postconstruction habitat conditions of the U.S. Army Corps of Engineers Bonneville project in Oregon and Washington. The project directly impacted 20,749 acres of wildlife habitat. Seven evaluation species were selected with losses and gains expressed in Habitat Units (HU's). One HU is equivalent to 1 acre of prime habitat. The evaluation estimated a gain of 2,671 HU's of lesser scaup wintering habitat. Losses of 4,300 HU's of great blue heron habitat, 2,443 HU's of Canada goose habitat, 2,76? HU's of spotted sandpiper habitat, 163 HU's of yellow warbler habitat, 1,022 HU's black-capped chickadee habitat, and 1,622 HU's of mink habitat occurred...
The purpose of the pilot project is to trial different methods and vendors of wind power forecasting to determine the best approach to forecasting wind power in Alberta in the future. Three vendors were chosen with global forecasting experience; AWS Truewind (New York), energy & meteo systems (Germany), and WEPROG (Denmark). Each vendor will forecast for 12 geographically dispersed wind power facilities for a year (May 07 to May 08) providing a forecast covering the next 48 hours refreshed hourly. ORTECH Power was chosen to perform the quantitative analysis of the results analyzing methods, timeframes and geographical locations. Phoenix Engineering was chosen to collect all the necessary meteorological data required...

Fish occurrence data to support high-resolution distribution models and test various community and macroecological hypotheses have not been available at the national scale. We present IchthyMaps, a database of high-quality historical fish occurrences covering fishes of the conterminous United States. Designed on the principles of metacommunity ecology, IchthyMaps is a compilation of presence records from atlases up to 1990, at the resolution of the 1:100,000 National Hydrography Database Plus (NHDPlus) inter-confluence stream segment, readily aggregated into hierarchically coarser units (e.g. hydrologic unit code 8-digit and 12-digit watersheds). IchthyMaps contains about 606,550 presence records for 1,038 species...

Conclusions:Chemical concentrations, turbidity, changes in microclimate, and sediment production were affected to varying degrees by forest harvesting. No significant differences were found between pre-harvest and post-harvest concentrations except for calcium which was 5 times higher and sodium which was 20 times higher in the harvested watersheds. Concentrations declined over the 3 year post-harvest span.Turbidity and suspended sediment increased with road construction but declined rapidly to nearly background levels after 2 years. Air temperature increased after harvesting in all of the smaller watersheds but stream temperature was not affected.Thresholds/Learnings:

Conclusions: Report identifies regional patterns of habitat disturbance, land use practices, and population trends relative to greater sage-grouse. In general, the most important landscape characteristics influencing sage-grouse populations are the proximity of leks (areas in which males perform to nesting habitat for and The report examined findings from studies that indicate several area and distance specific conservation thresholds for maintaining viable sage-grouse habitat. Thresholds/Learnings: Male sage-grouse prefer sod-forming grasses or bare ground for leks; female sage-grouse prefer dense sagebrush stands surrounding leks for nesting; gentle terrain characterized by <10% slope; <5% of existing sagebrush...
As electricity demand increases, policymakers must make decisions about which energy resources will meet future demands. Much of the recent literature has focused on the contribution of new coal power plants to carbon emissions (Milford et al., 2005; Milford et al., 2007; MIT 2007). However, policymakers and industry are increasingly interested in job creation and economic development analyses to understand the full impacts of new electricity generation projects.1 Additionally, economic development impacts are often a critical piece in building public support for wind power projects. The purpose of this research is to look at the specific factors that drive wind-power-related economic development and to better understand...

Conclusions: The amount of upstream impervious area affects downstream fish habitat quality, channel stability, and water quality. The use of riparian buffers can reduce the magnitude of urban impacts, however, they cannot fully mitigate the impacts of upstream development in the watershed. Threshold percentages of impervious areas , as well as the percentage of forest cover in a watershed appear to be the most effective indicators of watershed health. Thresholds/Learnings: Impervious areas should be kept at or below 10% of a watershed, and forest cover should be maintained at a minimum of 65% in order to effectively mitigate the impacts of urbanization and development on watersheds.

Emerging applications of ecosystem resilience and resistance concepts in sagebrush ecosystems allow managers to better predict and mitigate impacts of wildfire and invasive annual grasses. Soil temperature and moisture strongly influence the kind and amount of vegetation, and consequently, are closely tied to sagebrush ecosystem resilience and resistance (Chambers et al. 2014). Soil taxonomic temperature and moisture regimes can be used as indicators of resilience and resistance at landscape scales to depict environmental gradients in sagebrush ecosystems that range from cold/cool-moist sites to warm-dry sites. We aggregated soil survey spatial and tabular data to facilitate broad-scale analyses of resilience and...
