Wetland Types Ineligible for the
Missouri Agricultural Wetland Mitigation Bank Pilot Project

As identified and defined in (MO-180-V-NFSAM, Third Ed., Supplement MO1, October, 1997):

MISSOURI CATEGORICAL EXCLUSION AREAS:

  • Calcareous Fen - Wetlands saturated primarily by discharge of ground water. Fens
    are rarely inundated and often have a sloped surface. The soil may be dominated by
    deposits of calcium carbonate rich sediments (marl). Calcareous fen communities
    commonly have rare, threatened, and endangered species.
  • Bog - Peat accumulating wetlands characterized by deep saturated peat soils or a
    floating sedge/sphagnum mat.
  • Cypress/Tupelo Swamp - Bottomland permanently or seasonally inundated, and
    forested predominantly with bald cypress and swamp tupelo.

MISSOURI RED FLAG AREAS:

Wetlands that are, or that the manipulation of, would adversely impact areas: · Within a historical or archeological site as identified by SHPO.

· Protected by the American Indian Religious Freedom Act.

· Protected by the Ancient Graves and Marked Graves Act.

· Created, restored, or preserved for Clean Water Act (Sect. 404) purposes.

· Supporting a State or Federal threatened or endangered species.

          · Part of a hazardous waste site identified by USEPA or State EPA.

· Identified by the state as a natural or scientific area of importance.

          · A floodway, and project impacts will raise flood elevation above limits of county
            FEMA ordinances.

· Non-calcareous fens - fens w/o calcium or bicarbonate rich sediments.

· Impacted by channelization that results in a swampbuster violation.

· State and Federally listed wild and scenic rivers.

          · Mature bottomland woodland - "mature" definition will be based on "best  professional judgement" of the evaluation team relying on site characteristics and species composition.

 

ADDITIONAL WETLANDS IDENTIFIED BY THE MBRT

· Sedge meadows - Wetlands saturated to the surface for extended periods and
dominated by sedges.

· Moss-lichen wetlands - See Classification of Wetlands and Deepwater Habitats of the
United States, Cowardin, Et al. FWS/OBS-79/3!, December 1979.
