Waters and Wetlands Inventory – Coming Soon!
Often referred to as Version 2.0 of the
National Wetlands Inventory, the Surface
Waters and Wetlands Inventory provides more
inclusive geospatial data of all wetlands
and surface water features. This national
geospatial data product will contribute
substantially to improved modeling of flow
and water movement in surface water basins,
channels, and wetlands. For more

Product Summary web page.
of the Final National Wetland Plant List
The US Army Corps of Engineers, as part of an
interagency effort with the US Environmental
Protection Agency, the US Fish and Wildlife
Service and the US Department of Agriculture
Natural Resources Conservation Service, is announcing
the availability of the final 2012 National
Wetland Plant List (NWPL). The NWPL is used
to determine whether the hydrophytic vegetation
parameter is met when conducting wetland determinations
under the Clean Water Act and the Wetland Conservation
Provisions of the Food Security Act. The
list will become effective on 6/1/12.

Coastal Condition Report IV
The latest version of the National Coastal Condition
Report has been released by EPA. The reports describe
the ecological and environmental conditions in U.S.
coastal waters. They summarize the condition of ecological
resources in the coastal waters of the US and highlight
several exemplary federal, state, tribal, and local
programs that assess coastal ecological and water quality

2004 to 2009: Report to Congress on the status and trends
of our Nation's wetlands resources
This report is the latest in a continuous series spanning
50 years of wetlands data. It represents the most comprehensive

of Lands Inundated by the Flood Event of 2011
In April and May of 2011, flooding inundated
lands along the Ohio and Lower Mississippi Rivers.
Flood levels along portions of the Mississippi
River peaked at the highest levels since 1937.
An analysis of the extent of flooding was determined
by the comparison of MODIS imagery between pre-flood
and flood crest conditions.

Collection Requirements and Procedures for Mapping Wetland,
Deepwater and Related Habitats
With the adoption of new Federal Wetlands Mapping Standards,
the USFWS has developed an important
companion document (1MB PDF) that describes the
technical procedures and requirements for wetlands map
data. The document is intended to aid to organizations
or individuals mapping wetlands and applying the Cowardin
et al. classification system. This document explains
the appropriate application of wetland classification
and mapping process, and how to achieve the data quality
requirements now required in the new FGDC Standards.
System for Mapping Riparian Areas In The United States
standard (1.3MB PDF) is designed to guide current
and future riparian digital mapping projects. These
technical procedures serve as a reference for conducting
the image analysis work normally associated with mapping
riparian and associated habitats. A
riparian classification decoder and a
riparian classification system chart are also available.
Wetlands Mapping Standard
of the Interior Ken Salazar has announced the adoption
Wetlands Mapping Standard (PDF) that provides minimum
requirements and guidelines for wetlands mapping efforts.
The new standard is designed to guide current and future
wetlands digital mapping projects and enhance the overall
quality and consistency of wetlands data. Quality data
on wetlands are considered critical for planning effective
conservation strategies to benefit USFWS resources now
and in the future. (News
