Geospatial data that is a derivative land cover product depicting woodland on topographic maps.
Important policy issues concerning the mitigation of impacts from construction and development affecting wetlands are under examination by the U.S. Congressional Office of Technology Assessment, the Environment and Public Works Committee of the U.S. Senate, and the National Wetlands Technical Council. The issues divide into two main parts: (1) how the current strategy to simplify federal regulation of wetlands is limiting the success of mitigation; and (2) how to change the present strategy for mitigation under the U.S. Clean Water Act, if at all. Requirements for site-specific analysis of impacts and their mitigation requirements are being replaced by simple, uniform national guidelines on impact mitigation; these...
The WetlandsRiparian Web Map Service provides access to the Montana Spatial Data Infrastructure (MSDI) Wetlands and Riparian Framework dataset. Included in this service are the wetlands and riparian mapping program status map as well as historic, provisional and final wetlands polygon, outline, and labels. Metadata and access to the datasets that support this service is available through the Montana GIS Portal - http://gisportal.msl.mt.gov Additional information about these data sets and information about the Montana Wetlands and Riparian Center is available at - http://mtnhp.org/nwi/
This dataset was created from the combination of SSURGO data. Component-level data from SSURGO were derived from the dominant component in each mapping unit (the unit that had the highest representative percent of the mapping unit). Numeric horizon-level data from SSURGO were derived from an average average across all horizons within a component, and an area-weighted average between components. This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely...
Geospatial data that is a derivative land cover product depicting woodland on topographic maps.
The U.S. Fish and Wildlife Service (Service) is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands. The Service's strategic plan for our vast national wetland data holdings is focused on the development, updating, and dissemination of wetlands data and information to Service resource managers and the public. The development of the Wetlands Master Geodatabase is in direct response to the need to integrate digital map data with other resource information to produce timely and relevant managment and decision support tools. Wetlands provide a multitude of ecological, economic and social benefits. They provide habitat for fish, wildlife and a variety...

Geospatial data that is a derivative land cover product depicting woodland on topographic maps.
The Wetland Reserve Program (WRP) is a voluntary program administered by the NRCS. It provides technical and financial assistance to private landowners and Tribes to restore, protect, and enhance wetlands in exchange for retiring eligible land from agriculture. For a site to be a wetland eligible for restoration, it must be in a zone with sustained or frequent flooding for a period of 7 consecutive days on average at least once every 2 years (a value termed the 7MQ2). This study calculated the 7MQ2 flows for all the U.S. Geological Survey streamgages within the selected study reaches. These flows were related to the stage discharge tables for each streamgage and a corresponding elevation was determined. By use of...

The Forest and Rangeland Ecosystem Science Center 's mission is to provide scientific understanding and the technology needed to support sound management and conservation of our nation's natural resources, with emphasis on western ecosystems. The scientists from FRESC capitalize on their diverse expertise to answer critically important scientific questions shaped by the equally diverse environments of the western United States. FRESC scientists collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide. Research activities are concentrated in Washington, Oregon, Idaho, Nevada,...
Files contain hydrodynamic and sediment transport data for the location and deployment indicated. Time-series data of water depth, velocity, turbidity, and temperature were collected in San Pablo Bay and China Camp Marsh as part of the San Francisco Bay Marsh Sediment Experiments. Several instruments were deployed in tidal creek, marsh, mudflat, and Bay locations, gathering data on water depth, velocity, salinity/temperature, and turbidity. Deployment data are grouped by region (Bay channel (main Bay), Bay shallows, tidal creek, or marsh/mudflat/upper tidal creek). Users are advised to check metadata and instrument information carefully for applicable time periods of specific data, as individual instrument deployment...
