Description
The cypress-tupelo flood plain community tends to occur relatively close to the main channel in areas that are more frequently flooded and for longer periods of time.
Description
The flood plain bottomland hardwood forest tends to occur at some distance from the main channel in more stagnant backwater type settings that do not flood as often.
Description
This is a relatively wet site. Historically, these sites have been drained frequently to support a variety of land uses including forestry, agriculture, and development. This drained state is included in this STM because this state exists widely today across the landscape. Drainage of wetlands today is significantly regulated. NRCS is required to consider impacts to wetlands according to Federal laws including, but not limited to, the Clean Water Act, the Wetland Conservation provisions of the Food Security Act of 1985, and State, Tribal, and local laws. It is the policy of NRCS to protect and promote wetland functions and values in all NRCS assistance (National Environmental Compliance Handbook (NECH) 610.36).
Description
After land on this site has been drained, it is impossible to return fully to reference conditions that existed at that location prior to drainage, especially at locations that remained under active drainage management for long periods of time. Restoration efforts might include blocking and removing drainage structures, and revegetation.
Description
Any community on this site that has become salinized by the impacts of salt water inundation or intrusion. Saltwater intrusion is the movement of saltwater into freshwater systems. The process occurs mostly by lateral flow into areas adjacent to coastal waters or ditch systems that connect saltwater bodies. These ditch systems are designed to drain freshwater off of a site, but sea level rise and extreme tidal events push saltwater up these ditch systems and expose more of the landscape to salinization processes. Salinization can also occur as storm surge and/or extreme high tides push saltwater over the top of these terrestrial freshwater systems. Freshwater flooding can reduce salinization by flushing salts from the soil profile. Depending on the frequency and intensity of flooding, some salinization impacts may be only temporary in floodplain locations.
Mechanism
The drained state is included in this STM because this state exists widely today across the landscape. This transition is included to show how we got to where we are today. Drainage of wetlands today is significantly regulated. NRCS is required to consider impacts to wetlands according to Federal laws including, but not limited to, the Clean Water Act, the Wetland Conservation provisions of the Food Security Act of 1985, and State, Tribal, and local laws. It is the policy of NRCS to protect and promote wetland functions and values in all NRCS assistance (National Environmental Compliance Handbook (NECH) 610.36).
Mechanism
Sea level rise, tidal inundation, and soil saltwater intrusion.
