The national dataset was clipped to the WLCI envelope by USGS staff. No other processing was performed on the dataset. This map layer is commonly called Bailey's ecoregions and shows ecosystems of regional extent in the United States, Puerto Rico, and the U.S. Virgin Islands. Four levels of detail are included to show a hierarchy of ecosystems. The largest ecosystems are domains, which are groups of related climates and which are differentiated based on precipitation and temperature. Divisions represent the climates within domains and are differentiated based on precipitation levels and patterns as well as temperature. Divisions are subdivided into provinces, which are differentiated based on vegetation or other...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including...

This part of DS 781 presents data for the habitat map of the seafloor of the Offshore of Santa Cruz map area, California. The vector data file is included in "Habitat_OffshoreSantaCruz.zip," which is accessible from http://dx.doi.org/10.5066/F7TM785G.Using multibeam echosounder (MBES) bathymetry and backscatter data, potential marine benthic habitat maps were constructed. The habitats were based on substrate types and documented or "ground truthed" using underwater video images and seafloor samples obtained by the USGS. These maps display various habitat types that range from flat, soft, unconsolidated sediment-covered seafloor to hard, deformed (folded), or highly rugose and differentially eroded bedrock exposures....

This part of the Oregon OCS data release presents marine mammal observations from cruise 2014-607-FA in the Floating Wind Farm survey area. The survey was conducted using 12 hour day operations out of Charleston Harbor near Coos Bay, Oregon. The cruise plan consisted of 23 days on site split between sonar mapping and video ground truth surveying. Activities parsed out to nine days of sonar mapping, three days of video surveying, eight days of no operations due to weather, and three days mobilizing and demobilizing (table 1). Typically the Snavely would transit out to the survey area in an hour at a speed of 20 knots. Marine Mammal observations were made during the multibeam sonar mapping portion of the cruise only....

Habitat Conservation Plans (HCP) are planning documents required as part of an application for an incidental take permit under section 10(a)(1)(B) of the Endangered Species Act (ESA) of 1973. They describe the anticipated effects of the proposed taking, how those impacts will be minimized, or mitigated; and how the HCP is to be funded. HCPs can apply to both federally listed and non-listed species, including those that are candidates or have been proposed for listing. Conserving species before they are in danger of extinction or are likely to become so can also provide early benefits and prevent the need for listing.

This shape file represents an ecological boundary for the Crown of the Continent Ecosystem (CCE) as defined by the Crown Managers Partnership (CMP). The CMP developed the boundary through a series of meetings held in 2008, including a meeting between the CMP and non government organizations working in the Crown on July 23, 2008. The purpose of this exercise was to develop an ecological justification for the CCE, to enable analysis and tracking of the ecosystem from an ecological health perspective. The CMP notes that this extent does not represent the true economic, social and cultural impact on the CCE from surrounding urban areas. In Alberta the eastern boundary was delineated by the Foothills Fescue Subregion...

The Grizzly Bear Recovery Zone (GBRZ) for the Greater Yellowstone Ecosystem (GYE) delineates the area inside the GYE where demographic and habitat criteria were applied, monitored, and evaluated to achieve recovered status of the Yellowstone grizzly bear population. The GBRZ was established by the U.S. Fish and Wildlife Service (USFWS) in 1993 as part of the Recovery Plan for grizzly bears in the lower 48 conterminous United States. The recovery zone boundary identifies the known distribution of bears at that time and encompasses seasonal habitats needed to support a recovered population. The GYE recovery zone spans portions of Montana, Idaho and Wyoming and includes parts of 5 National Forests (Beaverhead-Deerlodge,...

The Colorado River is the dominant water source for the southwestern United States, crossing through seven states before reaching Mexico. The river supplies water to approximately 36 million people, irrigates nearly six million acres of farmland within and beyond the basin, and contributes an estimated 26 billion dollars each year to the region’s recreational economy. Yet the Colorado River’s water supply is already fully allocated, meaning that the economic and environmental health of the region is closely tied to the river’s streamflow. Climate projections for the Southwest show a future marked by chronic drought and substantial reductions in streamflow. The region has already been impacted by climate change,...

To understand potential climate change impacts on ecosystems, water resources, and numerous other natural and managed resources, climate change data and projections must be downscaled from coarse global climate models to much finer resolutions and more applicable formats. This project conducted comparative analyses to better understand the accuracy and properties of these downscaled climate simulations and climate-change projections. Interpretation, guidance and evaluation, including measures of uncertainties, strengths and weaknesses of the different methodologies for each simulation, can enable potential users with the necessary information to select and apply the models.

The Conservation Strategy Management Area (CSMA) is an area within which a delisted Yellowstone grizzly bear population was managed with the objective to maintain a stable to increasing population. The CSMA was formalized in the 2007 Federal Rule (72 FR 14866) which removed the Yellowstone distinct population segment from Federal protection as a threatened species under the Endangered Species Act. The CSMA was delineated as the area from within which the Yellowstone grizzly bear population size was estimated and sustainable mortality thresholds and demographic criteria were applied. The decision to replace the CSMA boundary with the Demographic Monitoring Area was first approved by the Yellowstone Ecosystem Subcommittee...

Fire in the western U.S. poses one of the greatest threats to human and ecological communities alike. In fact, fire management is the largest single expenditure of land management funds on federal lands. Now, climate change is altering wildfire patterns. Climate change in the West is creating warmer and drier conditions, resulting in an increase in the amount of dead vegetation available to fuel fires. This project sought to assess the vulnerability of forests in the southwestern U.S. to climate change and wildfire, in order to understand how these ecosystems might become altered as a result. Researchers (a) examined how climate change impacts wildfires in the region, to better understand fire risk; (b) identified...

The Distinct Population Segment (DPS) boundary is an area formalized in the 2007 Final Delisting Rule (72 FR 14866) which designates the Greater Yellowstone Ecosystem (GYE) population of grizzly bears (Ursus arctos horribilis) as a single and distinct population from the remaining populations in the lower 48 States. The U.S. Fish and Wildlife Service applied the DPS policy based on the discreteness and significance of the Yellowstone population segment in relation to the remainder of the taxon in the conterminous 48 States.
