This dataset is one of a dozen or so datasets that provide the basis for a vulnerability assessment of the Great Northern LCC that examines land use and climate changes at landscape scales, for the full LCC boundary. It provides a measure of vulnerability based on biome velocity and using hydrological-based analysis (hierarchical watersheds). The values range from 0 to 1 and are unitless, where Vhw = Eh x (1-Aw). The original floating point values ranging from 0-1.0 were multiplied by 100 and converted to integer format for this dataset.
Boundary of Mississippi River Basin derived by dissolving WBD HU-4, July 2012 version.

Despite the lack of surface flows, the Colorado River riparian corridor in Mexico has proven to be ecologically resilient. Floods in the 1980s and 90s in the region brought back large swaths of native riparian habitat, which still persist today in some areas along the river. Because the historic floodplain is extremely important for agricultural production and therefore the local economy, habitat maintenance must be integrated with continued utilization of lands and water for this purpose.The riparian, marsh, and open-water areas found in Reach 4 provide critical habitat for both migratory and resident riparian bird species. Due to its ecological importance, the riparian corridor and Reach 4 in particular have been...

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitoring the overall condition of the watershed, and by combining stream and soil monitoring within watersheds, the response of Adirondack ecosystems to environmental disturbances such as acid rain and climate change can be better understood. For example, the unexpectedly slow reversal of stream acidification from decreased atmospheric...

The NHDPlus Version 1.0 is an integrated suite of application-ready geospatial data sets that incorporate many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,000-scale NHD), improved networking, naming, and "value-added attributes" (VAA's). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first broadly applied in New England, and thus dubbed "The New-England Method". This technique involves "burning-in" the 1:100,000-scale NHD and when available building "walls" using the national Watershed Boundary Dataset (WBD). The resulting modified...

This project provides a regional assessment of sugar maple health and associated soil conditions in the Adirondack Region of New York, where sugar maple are a major component of the forest. The focus of the study is to develop an improved understanding of relationships among watershed characteristics, soil chemistry, and acidic deposition effects on sugar maple trees and other tree species that grow in association with sugar maple, which are one of the most highly valued tree species in the northeast. Project results are therefore important for the management of sugar maple in the Adirondack region where acidic deposition has lowered the nutritional status of soils by depleting calcium, a key nutrient for trees.Purpose...

Forest cores are derived by applying an inverse buffer (-100m) to forest patches to represent the area of contiguous interior forest habitat. Forest patches are defined as areas of contiguous natural cover bound by non-natural edge or linear fragmenting features (roads, railroads, transmission lines, natural gas pipelines). The following land cover types were selected from the 2006 National Land Cover Database (NLCD) to define “natural cover”: deciduous forest, coniferous forest, mixed [deciduous-coniferous] forest, scrub-shrub, woody wetland, and emergent wetland. Forest patches were delineated based on non-forest edge (from the NLCD) and the following linear fragmenting features:electric transmission lines (from...

The purpose of this data set is support resource allocation decisions (i.e. where to invest conservation effort) within the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative. It represents a relative ranking of HUC12 watersheds according to the quantity and quality of habitat as described in the GCPO LCC’s draft Integrated Science Agenda (v4). Watersheds (HUC12) were ranked by calculating the length-weighted average Management Opportunity scores within them. Because the 3 actions are identical for Med/Low-gradient Streams & Rivers of the coastal plains and Upland Streams & Rivers, (and because some watersheds contain both system types), we considered these systems simultaneously and calculated only...

This data release supersedes Thorson, J.M., Dunham, J.B., Heck, M.P., Hockman-Wert, D.P., and Mintz, J.M., 2020, Stream Temperature in the Northern Great Basin region of Southeastern Oregon, 2016-2019: U.S. Geological Survey data release, https://doi.org/10.5066/P924MOCB. This dataset includes hourly stream and air temperature data from 124 sites throughout the Northern Great Basin region of SE Oregon. Data loggers were deployed June through September of 2016 and downloaded each subsequent summer through 2021. The SE_OR_Stream_Temps and SE_OR_Air_Temps files contain temperature data (in C°) by logger serial number and site for the study period. The SE_OR_Wet_Dry delineation file contains daily flow status estimates...

In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA), the USGS Columbia Environmental Research Center, and the U.S. Environmental Protection Agency (USEPA) National Rivers and Streams Assessment (NRSA). One of the objectives of the RSQA, and thus the MSQA, is to characterize the relationships between water-quality stressors and stream ecology and to determine the relative effects of these stressors on aquatic biota within the streams (U.S. Geological Survey, 2012a). To meet this objective, a framework of fundamental...

This data set is a complete digital hydrologic unit boundary layer of the Subbasin (12-digit) 6th level for the entire United States, clipped to the Northeast. A hydrologic unit (HU) is a drainage area delineated to nest a multi-level, hierarchical drainage system. Its boundaries are defined by a hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surfaces waters. An HU can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. HUs are only synonymous with classic watersheds...
