Forest- Data collected once using GIS prior to fish sampling. Our approach was to focus the study on smaller, headwater catchments because larger streams drained areas containing both hemlock and mixed hardwood forest, making forest-specific comparison intractable. In addition, most of these larger watersheds were impacted by humans (e.g., impoundments, agriculture, quarries) that could confound our assessment of the influence of hemlock. Even after limiting the study to headwater catchments, other possible confounding factors remained; we controlled for landscape variability (i.e., terrain and stream size) through the sampling design and we excluded others (i.e., minimum catchment area,beaver activity) through...

This layer respresents First Nations Reservations that occupy area in the Crown of the Continent Ecosystem or occupy area within a 50 kilometer buffer surrounding the border. The data is derived from Alberta and British Columbia data from GeoGratis, which was created in 2003 and revised in 2015; and Montana data from the US Bureau of Land Management (BMSC).

This shapefile maps the 2012 vegetation communities for all historic wetlands in the Rainwater Basin region of Nebraska, USA. Vegetation communities include cropped areas that rarely pond water, cropped areas that often pond water, bare soil or mudflat, standing water, moist soil species, wetmeadow species, grasses, reed canarygrass, river bulrush, cattail, and woody species. Communities are based on training data from 2012 field vegetation surveys of over 12,000 points. This map is an update of a RWB vegetation map created in 2004. These data were processed by Ele Nugent, Roger Grosse, and Andy Bishop with the Rainwater Basin Joint Venture (RWBJV), with help from RWBJV Geographic Information Systems Laboratory...

Working with the conservation partnership in the Central Loess Hills BUL, this project was designed to develop the necessary baseline data and species habitat models needed to guide targeted conservation. Development of a conservation portfolio for the Central Loess Hills required five separate, but equally important elements. The elements of this project were: 1) Develop a spatially accurate landcover that delineates key habitats for which at-risk species respond, 2) Analyze landcover to develop meaningful landscape indices that can be used to develop spatially explicit species habitat models, 3) Collect and compile occurrence data for priority species (greater prairie chicken, whooping crane, and waterfowl), 4)...

Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of the program's data (plus 1953 data) has been preserved in this data release. Original field surveys documented bank erosion, aggradation, and degradation at 60 cross-sectional transects at annual or biannual timesteps. Three river reaches also have long-term longitudinal channel bed surveys which document the distribution and development...

This region-wide coordinated bird monitoring program, supported by state, federal, tribal, nongovernmental organizations, and two statewide bird conservation partnerships, is designed to provide spatially-referenced baseline data for science-based biological planning and conservation design for the Great Northern LCC and its partners that is directly comparable with other landscapes and BCRs. We are requesting a third year of funding to continue sampling in BCR10 Montana and Idaho to enhance our ability to make robust inference to bird populations on grassland, shrublands, and riparian systems. These data currently are being used by project partners to develop spatially-explicit models that will allow assessment...

This dataset provides transboundary census information in the Crown of the Continent Ecosystem. In Canada the data are from the 2011 census collected at the dissemination block level, in the United States the data are assembled from the 2010 census. Data on total population and total dwellings in each census unit are available. This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE. For more information on the CMP and its collaborators,...
The National Conservation Easement Database (NCED) is a collaborative venture to compile easement records (both spatial and tabular) from land trusts and public agencies throughout the United States in a single, up-to-date, sustainable, GIS compatible, online source. The goal of the NCED is to provide a comprehensive picture of the privately owned conservation easement lands, recognizing their contribution to America's natural heritage, a vibrant economy, and healthy communities. Conservation easements are legal agreements voluntarily entered into between landowners and conservation entities (agencies or land trusts) for the express purpose of protecting certain societal values such as open space or vital wildlife...
Habitat condition, both acres flooded and timing of inundation, were determined using remote sensing images from Landsat 5 and 8 for the Lower Klamath Basin, the representative basin for the southern Oregon and northeast California (SONEC) region. The dataset includes proportional water coverage (acres) for 8,825 distinct patches in Lower Klamath over 6 different time periods (1984-89; 1990-94; 1995-99; 2000-04; 2005-09; 2010-16), with a total of 368,301 acres of possibly foreageable land.
