Plug-in hybrid electric vehicles (PHEVs) have the potential to be an economic means of reducing direct (or tailpipe) carbon dioxide (CO2) emissions from the transportation sector However, without a Climate policy that places a limit on CO2 emissions from the electric generation sector, the net impact of widespread deployment of PFIEVs on overall US CO2 emissions is not as clear. A comprehensive analysis must consider jointly the transportation and electricity sectors. along with feedbacks to the rest of the energy system. In this paper, we use the Pacific Northwest National Laboratory's MiniCAM model to perform an integrated economic analysis of the penetration of PFIEVs and the resulting impact oil total U.S. CO2...

As the United States moves closer to a national climate change policy, it will have to focus on a variety of factors affecting the manner in which the country moves toward a future with a substantially lower carbon footprint. In addition to encouraging renewable energy, smart grid, clean fuels and other technologies, the United States will need to make substantial infrastructure investments in a variety of industries. Among the significant contributors to the current carbon footprint in the United States is the use of coal as a major fuel for the generation of electricity. One of the most important technologies that the United States can employ to reduce its carbon footprint is to sequester the carbon dioxide ("CO2")...

BLM REA CBR 2010 Greater Sage Grouse - Maximum connectivity value of sage grouse leks (reclassified)
Scorecard analysis for the terrestrial conservation element Greater Sage Grouse and current landscape permiability using circuitscape. The analysis is based upon location data using the lek locations (CBR_TS_C_175855_GSG_BreedingDensity100_poly). The cost surface is derived from the landscape condition score of current condition (CBR_DV_N_NATURESERVE_LANDSCAPECON_2010.img). This layer represents the maximum current value which has been reclassed all values that are > 1 = 1 and converted a 0-100 scale for analysis within a GIS. NatureServe’s ecological integrity framework provides a practical approach to organize criteria and indicators for this purpose (Faber-Langendoen et al. 2006, Unnasch et al. 2008). This framework...

This model provides one view of ecological integrity for the ecoregion, based on a model of near-future landscape condition, which has been summed into the 4x4km grid cells. Anthropogenic stressors come in many forms, from regional patterns of acid deposition or climate-induced ecosystem change, to local-scale patterns in agricultural drainage ditches and tiles, point-source pollution, land-conversion, and transportation corridors, among others. To be effective, a landscape condition model needs to incorporate multiple stressors, their varying individual intensities, the combined and cumulative effect of those stressors, and if possible, some measure of distance away from each stressor where negative effects remain...
BLM REA CBR 2010 Near-Future Scenario Footprint Assessment Change Agent/Grazing Allotments Intersect
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM grazing allotments (GAs) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) represented in the near-future (circa 2025)development scenario intersect with the areas of public land that are leased to private entities for grazing by livestock. It does not model actual response or condition of the GAs to the CAs. The data intersects two primary classes of information: The CAs consist of 20 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise...
These data were compiled in support of the 'Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants' project, supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis. The project working group compiled data for non-native insects herbivorous on three or fewer North American conifer families. Data were synthesized from existing resources for a variety of insect traits, traits of their North American conifer host trees, divergence time between the North American host trees and the host tree in the insects' native range, and native insects that feed on the same North American...
Federally owned and managed public lands occupy approximately 30 percent of the land area of the United States, and anywhere from 50 percent to more than 80 percent of the land area of many of the western states. Determining the appropriate use of these lands involves balancing objectives related to economic, recreational, and conservation interests. This paper examines established and emerging conflicts within and across these objectives through both a narrative discussion of specific topics and a series of case studies. The authors find that new challenges, including pressures to devote portions of public lands to renewable energy project development and the multifaceted threats presented by climate change, will...

Miscanthus is a newly introduced crop grown primarily to produce biomass for energy production and the area grown in the UK is anticipated to increase. Major differences in crop management from conventional arable crops have led to speculation that miscanthus may also have effects on farmland biodiversity. Six miscanthus fields were paired with six of a conventional crop, winter wheat, and bird diversity and abundance were compared in winter and during the breeding season along with potential food sources. Miscanthus fields had a greater abundance and diversity of birds than did wheat in winter and summer. In winter, the greater numbers of birds in miscanthus fields were probably attracted by the shelter provided...
Increased interconnection has been highlighted as potentially facilitating the integration of wind generation in power systems by increasing the flexibility to balance the variable wind output. This paper utilizes a stochastic unit commitment model to simulate the impacts of increased interconnection for the island of Ireland with large penetrations of wind generation. The results suggest that increased interconnection should reduce average prices in Ireland, and the variability of those prices. The simulations also suggest that while increased interconnection may reduce carbon dioxide emissions in Ireland, Great Britain would experience an increase in emissions, resulting in total emissions remaining almost unchanged....

High-temporal resolution meteorological output from the Parallel Climate Model (PCM) is used to assess changes in wildland fire danger across the western United States due to climatic changes projected in the 21st century. A business-as-usual scenario incorporating changing greenhouse gas and aerosol concentrations until the year 2089 is compared to a 1975 - 1996 base period. Changes in relative humidity, especially drying over much of the West, are projected to increase the number of days of high fire danger ( based on the energy release component (ERC) index) at least through the year 2089 in comparison to the base period. The regions most affected are the northern Rockies, Great Basin and the Southwest - regions...
Important policy issues concerning the mitigation of impacts from construction and development affecting wetlands are under examination by the U.S. Congressional Office of Technology Assessment, the Environment and Public Works Committee of the U.S. Senate, and the National Wetlands Technical Council. The issues divide into two main parts: (1) how the current strategy to simplify federal regulation of wetlands is limiting the success of mitigation; and (2) how to change the present strategy for mitigation under the U.S. Clean Water Act, if at all. Requirements for site-specific analysis of impacts and their mitigation requirements are being replaced by simple, uniform national guidelines on impact mitigation; these...
MBR Assessment Desert Tortoise Habitat Connectivity Model - normalized and converted to a 0-100 scale. This data is a model of potential habitat connectivity for the Mojave desert tortoise (Gopherus agassizii) for the Mojave Basin and Range ecoregion. Methods for developing this data set: The connectivity modeling software Circuitscape 3.5.7 was used to develop the desert tortoise model. The two inputs needed to model tortoise habitat connectivity with this software were developed in ArcGIS 10. Habitat Input: The USGS model for desert tortoise habitat potential was used to create a series of 167 points representing tortoise habitat throughout the Mojave Basin and Range ecoregion. Areas with high habitat potential...
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with sensitive soils (SS) in the Central Great Basin and Range ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas that were modeled by NatureServe to represent nine types of sensitive soils. It does not model actual response or condition of the SS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others...
This assessment raster is used to answer management questions (MQs) about where the Sage Grouse conservation element (CE) overlap with change agents (CAs). This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) and invasive annual grasses intersecting with Sage Grouse habitat. It does not model actual response of the CEs to the CAs; those more complex issues are addressed in different MQs and through different models. Areas for restoration/enhancement were indentified base upon the 3 quartile values (50>LC2025<=75, .5>AG<=.75). Areas of the CE distribution that are not overlapped by the 2025 development scenario (which includes current and 2025 devt), and that are not overlapped...

This raster is used to answer the management question (MQ) regarding areas of low potential for renewable energy development (solar, wind, geothermal) that could potentially mitigate impacts to CEs from potential energy development in the Central Basin and Range Ecoregion. The value indicated in the raster represents a score between 0-100, the lower values indicating areas of poor landscape condition (ecological integrity). The higher the score, better landscape conditions are expected. Areas in the middle of the spectrum likely offer areas that present opportunities for mitigation under the logic that these areas are likely to be mildly impacted by change agents and therefore present opportunities for mitigation/restoration....

This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) represented in the near-future scenario (circa 2030) intersect with HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist...
