Forestry Best Management Practices

Wetlands

Wetlands are areas where water is at, near, or above the land surface long enough to be capable of supporting aquatic or hydrophytic vegetation and which has soils indicative of wet conditions.  Iowa wetlands are diverse resources that include marshes, bogs, floodplain woodlands, wet meadows, low prairies and fens.

Wetlands provide many functional values in the ecosystem, among them:

· Shoreline Protection.
· Flood Protection.
· Water Quality Protection.
· Groundwater Recharge and Discharge.
· Wildlife and Plant Habitat.

Forestry BMPs in wetlands protect water quality and minimize changes to the surface and subsurface water.  Changes in the surface and subsurface water movement can affect the health of the wetland ecosystem and its flood protection function.

Activities in wetlands are often subject to municipal, county, state and federal permits and regulatory requirements.  If you suspect your project may involve a wetland and want to know what regulations apply, contact:

· Your County NRCS office,
· IDNR-EPD, Water Quality Section*
· U.S. Army Corps of Engineers*

*See Appendix A:  Resource Directory, Wetlands Section for more specific information.
 

BMPs for Wetlands:

  • Follow all planning BMPs in Chapter 2. Advance Planning
    Avoid locating roads and landings in wetlands.

  • When constructing roads in wetlands, see Appendix C: Woodland Roads - Federal Requirements for Woodland Roads in Wetlands, pg. 56.

  • Woodland management activities in wetlands should occur on frozen ground to minimize rutting.

  • For activities in wetlands, consider allowing more flexibility for completion dates in timber sales contracts to allow time to complete logging activities during firm or frozen ground conditions.

  • Do not move slash from upland sites into a wetland.

  • Keep slash out of open water.

  • Avoid equipment maintenance and fueling in wetlands.  Clean all spills promptly.  See Chapter 7.  Fuels, Lubricants, Wastes and Spills.
