Construction to Reduce Mosquito Breeding Habitat Moving Forward at Bandon Marsh

Bandon, Ore. – Ducks Unlimited and the U.S. Fish and Wildlife Service will begin work to add tidal channels to drain mosquito breeding habitat at Bandon Marsh National Wildlife Refuge on July 15. This work is part of Service’s Integrated Marsh Management Approach to control mosquitoes at the refuge through long-term habitat modification and mosquito control treatments.

Ducks Unlimited awarded a contract to Magnus Pacific to construct 46,000 linear feet of new tidal channels on the Ni-les'tun Unit of the Refuge beginning this month. Small channels up to two feet wide by two feet deep will drain breeding pools that salt marsh mosquitoes require to breed. This will also improve tidal flow within the marsh. Excavation equipment to be used will be specialized to allow operation on soft marsh surfaces without causing significant damage or creating new depressions.

"Improving tidal flow throughout the restored tidal marsh in the Ni-les'tun Unit of the Refuge will greatly reduce mosquito breeding habitat while improving fish and wildlife habitat," said Refuge Project Leader Roy Lowe.

Ducks Unlimited has been working closely with Refuge staff to design and engineer the new channel system, with funds provided by the U.S. Fish and Wildlife Service and the Oregon Watershed Enhancement Board. Construction is scheduled to be completed by mid-September. The U.S. Fish and Wildlife Service will continue to work with Coos County Public Health to monitor and control mosquitoes on Bandon Marsh using the larvicide Bti until permanent habitat modifications are completed and are properly functioning.
