Collection of 4 assessments for Upland Streams and Rivers. The Condition Index ranks stream segments according to how well they meet the Desired State described qualitatively and quantitatively in the draft Integrated Science Agenda (v4). From the Condition Index, 3 assessments are derived that rank opportunities for management and restoration of conditions included in the Condition Index – Watershed Land Use, Riparian Cover, and Stream Meander. Watershed Land Use management opportunities are based on the proportion of undisturbed land in the contributing (i.e. cumulative) watershed such that stream segments meeting the Desired State are considered Maintenance opportunities (values 5-6). Those that do not meet the...

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. The Protection Opportunity action map for the Upland Hardwood (Woodland) habitat system ranks pixels (250-m) based primarily on the Upland Hardwood (Woodland) Condition Index such that unprotected sites within healthy landscapes are ranked higher than those in very fragmented landscapes. Ranks are increased by information on existing partner interest (i.e. stated priority areas), elevated risk of change by 2060, and predicted occupancy of a majority of species identified in the GCPO LCC’s draft Integrated Science Agenda (v4)....
Integrating spatial data for predicting the influence of altered hydrologic and thermal conditions on fish and macroinvertebrate assemblage traits and taxa across stream
Stream hydrology and temperature are among the most influential regulators of life-history traits and community structure of aquatic organisms. Hydrologic and thermal gradients strongly affect individual fitness and ultimately species success by imposing fundamental constraints on behavior, metabolic rates, reproduction, growth and ecological interactions. Stream hydrology and water temperature are also among the most frequently altered components of lotic systems due to human activities and other environmental disturbance. Despite their critical role in sustaining native aquatic biodiversity, few studies have examined the cross-scale influence of hydrology and water temperature on freshwater biota using a multi-species...

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 the presence, quantity and quality of the Open Pine habitat system (includes longleaf, shortleaf and loblolly systems) within the 5 sub-geographies of the GCPO LCC region. Once ranked, watersheds were classified (e.g., “Top 10%”) based on the proportion of the total Open Pine area (current + potential) contained within the...

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. The Management Opportunity action map for the Tidal Marsh habitat system ranks pixels (10-m) for 3 general classes of conservation actions. Maintenance pixels (values 7-9) are currently estimated to meet the site condition Endpoints in the GCPO LCC’s draft Integrated Science Agenda (v4). Enhancement pixels (values 4-6) are those that are currently classified as Tidal Marsh but do not meet the site condition Endpoints in the Science Agenda. Restoration pixels (values 1-3) are those that are currently in a different land use but...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
