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...
Land managers have incorporated threats to biodiversity for nearly two decades, but very few efforts have included threats from future conditions and fewer still have assessed vulnerability to climate change. This project will address two themes: 1) providing foundational information about habitat fragmentation and connectivity and 2) identifying the degree of vulnerability of key habitats to climate change.For development of understanding broadextent, a landscape-level pattern of climate change is an important complement to approaches to estimate rangeshifts for certain key focal species. Ecological system types (i.e. coarsefilters) are widely used in conservation planning because they contain valuable resources...

Carbon Capture and Storage (CCS) is a critical part of the global effort to address climate change as CCS has the potential to achieve deep cuts in CO2 emissions to atmosphere from the use of fossil fuels. In this context, pre-combustion capture through Integrated Gasification Combined Cycle (IGCC) power plants with CCS is one of the key pathways to low emissions power generation. There are, however, very significant challenges to the development, commercialization and deployment of IGCC with CCS technologies. This article examines matters of cost, the need for government support to early movers, the attribution of economic value for carbon dioxide and various other regulatory, policy, technical and infrastructural...
A comprehensive list of 38 categories of anthropogenic drivers of change in marine ecosystems developed through expert workshops (S1) was assessed for data availability on a global scale. We intentionally did not further subdivide these categories into unique drivers (e.g. each specific type of pollutant) as this would lead to over-emphasis of certain activities when impacts are summed. We limited our analyses to anthropogenic drivers with pre-existing global coverage or those for which we could assemble or develop global coverage. Although many regional-scale data and data with a global scope but incomplete coverage exist for a variety of specific human activities, inclusion of these data would bias global comparisons...
Although the impacts of exotic plant invasions on community structure and ecosystem processes are well appreciated, the pathways or mechanisms that underlie these impacts are poorly understood. Better exploration of these processes is essential to understanding why exotic plants impact only certain systems, and why only some invaders have large impacts. Here, we review over 150 studies to evaluate the mechanisms underlying the impacts of exotic plant invasions on plant and animal community structure, nutrient cycling, hydrology and fire regimes. We find that, while numerous studies have examined the impacts of invasions on plant diversity and composition, less than 5% test whether these effects arise through competition,...
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM Herd Management Areas (HMAs) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) from the near-future scenario (circa 2025) that intersect with areas managed for wild horses and burros in the western US. It does not model actual response or condition of the HMAs 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 footprints (pipelines, roads, energy...
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 Mojave 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 assessment raster is used to answer management questions (MQs) about where the Bighorn Sheep conservation element (CE) overlap with change agents (CAs). This is a basic footprint assessment of anthropogenic features (urban development, roads, etc). 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
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...
