We summarize available information on Pacific walrus haulouts from available reports, interviews with coastal residents and aviators, and personal observations of the authors. We provide this in the form of a georeferenced database that may be queried and displayed with standard geographic information system and database management software. The database contains 150 records of Pacific walrus haulouts, with a summary of basic characteristics on maximum haulout size, age-sex composition, season of use, and decade of most recent use. Citations to reports are provided as a bibliographic database.

These heatmaps show a top 3 stressor or service, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor or service across the landscape. This map shows the percentage of participants from each county and municipality who ranked Shifting Climate Zones as a top 3 ecosystem stressor in the Montane Ecosystem Functionality category in their region. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for...

This dataset describes groundwater quality monitoring wells in the vicinity of the Badger Army Ammunition Plant in Sauk County, Wisconsin, and information associated with each unique well. This includes the values used for mapping plume boundaries, concentration trends for contaminants in each individual well, and monitoring optimization results from the Monitoring and Redediation Optimization System (MAROS) analysis.

In 2007, American Wildlands (Bozeman, MT) initiated a "Priority Linkage Assessment" (PLA) through which we have identified, cataloged and prioritized the threats to, and opportunities for, maintaining connectivity in the U.S. Northern Rockies (Montana, Idaho and Wyoming). The process involved interviewing wildlife movement and connectivity experts from state and federal agencies, and independent biologists with proven knowledge of wide-ranging wildlife. The experts were asked to use their professional and personal experience in the field (knowledge of related scientific studies and their own field research) to identify important areas of wildlife connectivity ("linkages" - defined as as a specific area through which...

Wildlife carcasses recorded by Montana Department of Transportation, Idaho Department of Fish & Game, and U.S. Fish & Wildlife Service were aggregated to the nearest mile marker for major roads of the U.S. Northern Rockies. WGA connectivity flowlines were intersected with the road network and attributed to the nearest mile marker, along with their connectivity ranking, which indicates their expected relative importance to maintaining westwide connectivity. Values for potential risk factors, including average annual daily traffic (AADT), functional class, number of lanes, road surface width, landscape condition of surrounding habitat, ruggedness of surrounding landscape, and topographic position relative to surrounding...

In 1976-1981, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaii Forest Bird Surveys (HFBS; Scott, J.M., S. Mountainspring, F.L. Ramsey, and C.B. Kepler. 1986. Forest bird communities of the Hawaiian Islands: their dynamics, ecology, and conservation. Studies in Avian Biology 9:1-431). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in Hawaii during the past two decades. Unfortunately, these estimates and range maps are now seriously outdated, hindering modern conservation decision-making efforts...

This layer represents the major road network of the U.S. Northern Rockies. It was created by merging Montana Department of Transportation "on-system" routes with Idaho Transportation Department "state highway system" routes, creating consistent attribute fields, then clipping to the U.S. Northern Rockies study area boundary.
