This shapefile is the official boundary of the Western Native Trout Initiative. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Western Native Trout Initiative, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

The NABat sampling frame is a grid-based finite-area frame spanning Canada, the United States, and Mexico consisting of N total number of 10- by 10-km (100-km2) grid cell sample units for the continental United States, Canada, and Alaska and 5- by 5-km (25km2) for Hawaii and Puerto Rico. This grain size is biologically appropriate given the scale of movement of most bat species, which routinely travel many kilometers each night between roosts and foraging areas and along foraging routes. A Generalized Random-Tessellation Stratified (GRTS) Survey Design draw was added to the sample units from the raw sampling grids (https://doi.org/10.5066/P9M00P17). This dataset represents the final 2018 NABat Sampling grid with...

This data release comprises a dataset that contains sample collection information and microsatellite genotypes, and another dataset that contains single nucleotide polymorphism (SNP) genotypes with sample collection information for populations of white-tailed ptarmigan across the species' range. There is also an additional file (accession numbers.xlsx) linking samples to accession numbers in Genbank. This data was collected in order to address the following: The delineation of intraspecific units that are evolutionarily and demographically distinct is an important step in the development of species-specific management plans. Neutral genetic variation has served as the primary data source for delineating units for...

The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections under the U.S. Geological Survey's project titled "Quick Assessment of Rare and Critical Metals in Ore Deposits: A National Assessment" (2008 to 2013) in an effort to begin an assessment of the Nations' previously mined ore deposits for critical minerals. Mineralized and altered rock samples were provided by the Colorado...

In 2016, with National Park Service support, several previously undated plutons were sampled in Glacier Bay National Park and Preserve along the west side of Glacier Bay for age determinations. Geochronologic analyses were conducted to determine the ages of the plutonic rocks in the Glacier Bay area. Five samples were collected by Frederic Wilson (USGS Alaska Science Center), from Dundas Bay and Geikie Inlet, and dated by laser ablation-inductively coupled plasma mass spectrometry U-Pb methods. The dates obtained ranged from approximately 112-118 Ma, indicating that these samples are younger than the Saint Elias plutonic suite (ca. 160 Ma-130Ma), which runs along the same trend as the sampled rocks to the south.
This project will provide a comprehensive synthesis of beaver recolonization science and techniques for successful reintroduction or population expansion through a thorough, in-depth, coordinated review of all North American beaver-related information, including identification of research gaps and data needs, and recommendations for project implementation. This information will be disseminated through a series of one-day workshops.

This project will create a targeted and easily understandable guide to tools that support landscape-level planning in the face of climate change for NPLCC partners. The guide will build on previous NPLCC research on decision support needs with an emphasis on tools currently in use in the region. A survey of NPLCC partners will discover who is currently using or planning to use tools in the region, tools they are using, how well these tools are meeting their needs, and regional and outside experts engaged in tool use. Additional tools research will provide information on tools not currently in use in the region that could also provide needed functionality.

The Tongass National Forest has identified resources that are important to stakeholders and vulnerable to climate-related stressors. Cooperators will review an action plan and convene a workshop to be held in Southeast Alaska in 2016. The workshop will foster collaboration between scientists, managers, and stakeholders. Workshop goals include: sharing information about climate-related stressors and effects on NPLCC Priority Resources in the Tongass National Forest; developing strategic priorities for improving understanding, reducing risks, and increasing adaptive capacity and resilience; coordinating support for increasing knowledge and informing resource managers
