Working in conjunction with principal
Federal agencies the USFWS and NOAA have
produced updated data on more recent trends
of wetlands in the coastal watersheds to
help prioritize conservation planning
efforts and contribute additional
information on coastal wetland trends. This
report updates and expands previous
information on coastal wetland loss by
incorporating new data for the coastal
watersheds of the Atlantic, Gulf of Mexico
and Great Lakes and in addition, providing
information for the Pacific coast along the
States of Washington, Oregon and California.

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

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

An analysis of the extent of flooding was determined
by the comparison of MODIS imagery between pre-flood
and flood crest conditions.
