"This data layer represents information on the characteristics, extent, and status of wetlands in the Sacramento delta area. This metadata file incorporates new information to the metadata of the original source data. This new information is indicated in quotation marks." The National Wetlands Inventory (NWI) of the U.S. Fish & Wildlife Service produces information on the characteristics, extent, and status of the Nation's wetlands and deepwater habitats. The 'WETLANDS' coverages are digitized polygon coverages describing ecological taxa, arranged in a system useful to resource managers. They furnish units for mapping and provide uniformity of concepts and terms. Wetlands are defined by plants, soils and frequency of flooding. Generally, wetlands are lands whereby water saturation is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface. Five defined systems form the highest level of the classification hierarchy: Marine, Estuarine, Riverine, Lacustrine, and Palustrine. All but the Palustrine system are broken into subsystems in which classes are based on substrate material and flooding regime or on vegetative life form. Six classes are based on substrate and flooding regime: 1) Rock Bottom with a substrate of bedrock, boulders or stones; 2) Unconsolidated Bottom with a substrate of cobbles, gravel, sand, mud or organic material; 3) Rocky Shore with the same substrate as Rock Bottom; 4) Unconsolidated Shore with the same substrate as Unconsolidated Bottom; 5) Streambed with any of the substrates; and 6) Reef with a substrate composed of the living and dead remains of invertebrates (corals, mollusks or worms).
"This data layer was edited from its original source data set for inclusion in the Russian River Watershed Adaptive Management Plan (RRWAMP) and RRWAMP Baseline Watershed Assessment project. The intended use of this data layer in this project is to examine landscape or human factors to promote ecological health and sustainability within the Russian River watershed." This dataset was originally created as a need to map the State's resources, which include wetlands. As part of the mapping effort, there is a continuing need to map and/or update areas that have not yet been mapped.
The National Wetlands Inventory Center information is used by Federal, State, and local agencies, academic institutions, U.S. Congress, and the private sector.
TEALE Data Products
===================
Starting July 1, 2001 some of California's physical and cultural
geospatial information, formerly distributed by the Teale Data Center,
is being distributed to the public by the California Mapping
Coordinating Committee through servers at the California Environmental
Resources Evaluation System (CERES) in the Resources Agency and
National Aeronautics and Space Administration (NASA) Ames Research
Center.
There are no plans to actively maintain the currentness of these data
products. In fact, updates to these data typically result in the
creation of new data products, and is not represented as changes to
these data. These data should be considered a snapshot of data as
existed typically in the early and mid nineties.
AREA : The area of the polygon in square coverage units.
PERIMETER : The length of the polygon perimeter of the polygon
in coverage units.
NWI{BAY | DELTA}# : The software-assigned unique integer
identification number.
NWI{BAY | DELTA}-ID: A user-assigned identification number.
WTYPE: Values identifying wildlife type
HTYPE: Numerical value identifying habitat type
BAY: Identifies whether body lies within or outside the
bay
Space limitations require that the following table be split.
Section 1 shows Wildlife Habitat Type, NWI System/Class, and H Type.

There are large numbers of small (ponds, etc.) polygons throughout the coverage. Sliver elimination is almost impossible to perform without significant "real" data loss. Great care must be taken in processing these coverages. They push the capabilities of GIS systems. Attempts were made to subdivide large polygons. Occasionally more subdivision is required to prevent software failures. The attribute completeness seems to be good, considering the numbers of polygons present. Some assignments seem strange at first glance, i.e., sewage treatment ponds show up as freshwater, diked ponds. A few (4-5) gross labeling errors were encountered and corrected as per knowledge of field biologists working in the area (1991).
"Data were checked for spatial/geographic logic and consistency."

"This data layer was created for the Russian River Watershed Adaptive Management Plan (RRWAMP) and RRWAMP Baseline Watershed Assessment project through minor editing to the original source data. Data were clipped to the project study area boundary (rr_watershed_bndy.shp) and projected using ESRI's ArcGIS GeoProcessing tools; and renamed to the current file name."
