This layer depicts the status, or degree of disturbance, to plant communities on the main Hawaiian Islands. To more precisely identify areas where native species may presently be found, a map was generated that considers the following three categories of habitat quality: High, areas dominated by native vegetation; Medium, areas dominated by nonnative vegetation; and Low, highly modified landscapes. The primary source for mapping these three categories is the HIGAP land-cover classification (Gon, 2006). The High category includes all HIGAP land-cover classes that are considered to be either native dominated or mixed native and nonnative in order to represent those areas that have substantial native-species composition....

OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Science Analytics and Synthesis (SAS) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization) International Oceanographic Data and Information...

This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Data consist of spotted frog counts aggregated by date, location, and life stage, as well as data on environmental conditions at the time of each survey.

***This dataset is superseded by Adams, M.J., Pearl, C.A., McCreary, B., Galvan, S.K., and Rowe, J.C., 2019, Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2018 (final): U.S. Geological Survey data release, https://doi.org/10.5066/P9L2XC5B.*** This dataset contains information from mark-recapture surveys conducted in 2015 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts aggregated by date, location, life stage, and sex, as well data on environmental conditions at the time of each survey.
This database contains literature citations and associated summaries pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on the Oregon spotted frog (Rana pretiosa) and other listed/sensitive wetland-breeding amphibians in the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance. *HINT: If you are looking for the database SEARCH TOOL, scroll down to 'Attached Files' and download 'Annotated_bibliography_with_search_tool.accdb.'

The invasion of 40 million hectares of the American West by cheatgrass (Bromus tectorum L.) has caused widespread modifications in the vegetation of semi-arid ecosystems and increased the frequency of fires. In addition to well-understood mechanisms by which cheatgrass gains competitive advantage, it has been implicated in reducing arbuscular mycorrhizal fungi (AMF) abundance and taxa diversity. We evaluated this possibility at a high elevation site in a two-pronged approach. To test whether cheatgrass changed native AMF communities in ways that affected subsequent native plant growth, we grew cheatgrass and native plants in native soils and then planted native plants into these soils in a greenhouse experiment....

Calfifornia condor occurrence data, downloaded from USGS BISON. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, with relevant geospatial layers. Species occurrences are records of organisms at a particular time and location that are often collected as part of biological field studies and taxonomic collections. These data serve as a foundation for biodiversity and conservation research. BISON supports several data interchange formats to enable developers to write custom applications (http://bison.usgs.ornl.gov/services.html). The BISON...

The polygon (vector) feature class represents locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas (SFAs) in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The mineral-resources tracts are geographic areas that were assessed by the USGS and were determined to be geologically favorable for a deposit type of interest to a depth of 1 kilometer. Qualitative assessment methods outlined by the Bureau of Land Management (BLM) were used to develop tract boundaries and to assign a level of mineral-resource potential and certainty to each tract. The general process included (1) identifying possible mineral...

We used visual surveys to document the presence of all life stages of Cascades frog (Rana cascadae) at historically occupied sites. We surveyed 67 sites 1-2 times between May and August of 2018 and 2019. This effort was a continuation of 2001-2004 surveys conducted at the same site pool. This dataset includes counts of amphibians, reptiles, and fish observed during each site survey, as well as habitat covariates.

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the time each survey. Note that due to updates in access permissions, surveyed area within each site varies over time. Thus, counts are not comparable among year, as surveyed area was not held constant.

This table contains Carbon and Nitrogen stable isotope data for Silver Chub (Macrhybopsis storeriana), dreissenid mussels, and Hexagenia spp. mayflies from western Lake Erie in 2014. Samples were collected between May and September 2014 as part of both routine monitoring and a lake-wide coordinated monitoring effort. Silver Chub were collected in trawls; Hexagenia and Dreissenids were captured in benthic samples and taken from Silver Chub diets.

Trout Unlimited will extend its existing Adopt-a-Trout program to the Henrys Fork River, a tributary to the Green River in the Colorado River basin. The project will include work with the Wyoming Game and Fish Department and local schools to tag and monitor Colorado River Cutthroat trout movements to learn more about fish passage issues, areas of high entrainment, habitat use, and native and wild trout migratory patterns. Colorado River Cutthroat trout are native to the Henrys Fork River and occupy portions of the drainage; however, no data exists for Colorado River Cutthroat trout in the Wyoming portion of the Henrys Fork drainage to understand population dynamics and habitat restraints.FY2014Trout Unlimited will...

Data are included for laboratory studies evaluating the thermal biology of several freshwater mussel species and their host fish including dwarf wedgemussel (Alasmidonta heterodon), brook floater (Alasmidonta varicosa), creeper (Strophitus undulatus), eastern elliptio mussel (Elliptio complanata), tesselated darter (Etheostoma olmstedi), and slimy sculpin (Cottus cognatus). Thermal endpoints include critical thermal maximum, temperature preference, oxygen consumption rates, and clearance rates of organisms acclimated to a range of temperature treatments.

Interactions between geomorphic processes at multiple scales shape the distributions of habitats, species, and life stages that a river can support. Understanding these hierarchical processes may be helpful for proactive monitoring and restoration of native Western Brook Lamprey (Lampetra richardsoni) and Pacific Lamprey (Entosphenus tridentatus) in Pacific Northwest rivers. The processes creating thick, fine-grained sediment deposits that lamprey larvae rely on as rearing habitat were assessed in part through field sampling in the Umpqua River basin, southwestern Oregon, USA. Local factors, such as substrate, boulders, wood, and water, that control sediment erosion and deposition, affecting larval lamprey habitat,...
