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
Flood plain marsh is a community dominated by graminoids, herbs, and shrubs occurring within a river or stream flood plain. This community is disturbance dependent, or it will quickly succeed to a woody dominated community. In many locations, especially in Florida, fire may provide the necessary disturbance vector. Flood plain marsh adapted species typically sprout readily following fire.
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.
Mechanism
Stand killing disturbance including scour, deposition, and/or fire.
