Presentation Transcript

  1. Wetland Habitats: EMWMF Haul Road Remediation • In 2005 a large haul road was constructed that resulted in loss of wetlands. • To compensate for those losses, new wetlands were created. Haul Road Remediation site

  2. Wetland Habitats: EMWMF Haul Road Remediation • An artificial channel was created to connect upper and lower Bear Creek, bypassing an old weir dam that had isolated the stream sections. • The area behind the weir was filled to create a new wetland habitat. Artificial channel Old weir Remediated wetland

  3. Bear Creek Wetland Habitats: EMWMF Haul Road Remediation A new stream section was designed to mimic existing Bear Creek.

  4. Wetland Habitats: EMWMF Haul Road Remediation A new wetland was created by filling the old Bear Creek channel behind the weir.

  5. Wetland Habitats: EMWMF Haul Road Remediation July 2006 July 2007 Vegetation established rapidly in the created wetland.

  6. Wetland Habitats: EMWMF Haul Road Remediation • Monitoring in 2007 indicated rapid establish-ment of a diverse wetland plant community.

  7. Wetland Habitats: EMWMF Haul Road Remediation • Monitoring in 2008 indicated continued improve-ment in percent cover of remediated plots.

  8. Wetland Habitats: EMWMF Haul Road Remediation • Good survival and growth of planted tree and shrub sprigs continued in 2008.

  9. Wetland Habitats: EMWMF Haul Road Remediation • Site will continued to be monitored in the future. • Hydrologic changes have resulted in some bypass of spring water to the wetland. • Engineers will evaluate potential modifications to the existing flow paths to the wetland. • Further management may be required to insure adequate hydrology and to control invasive plants.
