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.

More information on the Integrated Marsh Management Approach can be found on the refuge’s mosquito web page www.fws.gov/oregoncoast/bandonmarsh/Mosquito.html.

Coos County plans to use airplane to treat Bandon Marsh Refuge with mosquito larvicide

Bandon, Ore. – This weekend, part of the Ni-les'tun Unit of the Bandon Marsh National Wildlife Refuge will be treated with Bacillus thuringiensis israelensis, or Bti, for the fourth time this season. The Bti is scheduled to be applied by an airplane. Neighbors should expect to see a very low-flying plane over the Ni-les'tun marsh this weekend. The aerial application of mosquito larvicide will not affect the nearby Coquille River or areas around the Ni-les'tun Unit.

The flight is scheduled for Saturday, June 14, weather permitting. Sunday, June 15, will be the fallback day if the flight needs to be rescheduled.

"Using a fixed wing aircraft, granular Bti will be applied from very low altitude reducing all drift. The application will take approximately three hours to complete," said Dan Markowski of Vector Disease Control International, the Coos County Public Health contractor that conducts the larvicide applications.

Some areas of the marsh will also be treated by hand with backpack spreaders.

A large portion of the marsh was flooded by the current high tide series and will need to be treated with the mosquito larvicide Bti. The mosquito larvae are only susceptible to Bti for a few days after they hatch, and must be treated during that time. Using the airplane to apply the mosquito larvicide is the most efficient way to treat such a large area, over 170 acres, of the marsh.

Bti is a naturally derived larvicide that kills mosquitoes in their aquatic immature life stages. Bti targets mosquito larvae and is not toxic to bees, moths, butterflies, fish, mammals, or birds.

All tidal marsh areas in the refuge where mosquito larvae exceed set threshold levels will be treated as necessary throughout the summer. Monitoring will be ongoing to determine when Bti treatment is necessary.

Funding provided by the Service was previously released to Coos County Public Health for monitoring and application of larvicide. The County hired a field technician to monitor for mosquitoes on the Refuge and nearby areas throughout the spring and summer. The County has also contracted with Vector Disease Control International to apply the larvicide Bti as needed.

Treatment of mosquitoes with larvicide is part of the Integrated Marsh Management Approach to control mosquitoes at the refuge through long-term habitat modification and mosquito control. Tidal channel construction to eliminate mosquito breeding habitat is scheduled to begin this July.

Coos County treats Bandon Marsh with mosquito larvicide
Bandon, Ore. – The Ni-les’tun Unit of the Bandon Marsh National Wildlife Refuge was treated with Bacillus thuringiensis israelensis, or Bti, from May 17-20, 2014. The granular formulation of Bti was applied by hand and backpack spreaders. All tidal marsh areas where mosquito larvae exceeded set threshold levels were treated. Monitoring will be ongoing to determine when Bti treatment is necessary.

“Coos County and the Service are continuing to work cooperatively on mosquito monitoring and treatment. Bti will be applied as needed based on the presence of larvae in the Ni-les’tun Unit.” said acting refuge manager Madeleine Vander-Heyden.

Funding, provided by the Service, was previously released to Coos County Public Health for monitoring and application of larvicide. The County hired a field technician to monitor for mosquitoes on the Refuge and nearby areas throughout the spring and summer. The County has also contracted with Vector Disease Control International to apply the larvicide Bti as needed. Bti is a naturally derived larvicide that kills mosquitoes in their aquatic immature life stages. Bti targets mosquito larvae and is not toxic to bees, moths, butterflies, fish, mammals, or birds.

The Service purchased 16 mosquito traps for loan to Coos County. Four were delivered to the City of Bandon on May 19 and the other 12 will be arriving by the end of the month. The city and the Coos County Vector Control Advisory Committee are expected to determine trap placement. Additionally, the Service will provide a grant of three thousand dollars to a local nonprofit who will work with the Coos County Vector Control Committee to build and deploy bat boxes around the community.

Treatment of mosquitoes with larvicide is part of the Integrated Marsh Management Approach to control mosquitoes at the refuge through long-term habitat modification and mosquito control. Tidal channel creation to eliminate mosquito breeding habitat is scheduled to begin in early summer 2014.

Coos County to begin treating Refuge with mosquito larvicide
Bandon, Ore. - Coos County Public Health will begin ground application of Bacillus thuringiensis israelensis, or Bti, on Bandon Marsh National Wildlife Refuge starting this weekend, May 3-4, 2014. Bti is a naturally derived larvicide that kills mosquitoes in their aquatic immature life stages as they hatch in breeding pools. Bti targets mosquito larvae and is not toxic to bees, moths, butterflies, fish, mammals, or birds. The granular formulation will be applied by hand and backpack spreaders and restricted to areas within the Ni-les’tun Unit of the Refuge.

“Bti will effectively control mosquitoes on the Ni-les'tun Unit of the Refuge while posing a low risk to wildlife, their habitats, and the human environment. Coos County Public Health will be treating the refuge as needed throughout the summer, as determined by ongoing monitoring, to prevent larvae from developing into adults.” stated Refuge Project Leader Roy Lowe.

Funding, provided by the Service, was previously released to Coos County Public Health for monitoring and application of larvicide. The County has hired a field technician to monitor for mosquitoes on the Refuge throughout the spring and summer in concert with Refuge employees. The County has also contracted with Vector Disease Control International to apply the larvicide Bti, as needed.

Treatment of mosquito larvae could not move forward until the appropriate permitting and legal planning documents, like the two recently finalized environmental assessments, were completed. The two EAs comprise the Integrated Marsh Management Approach to control mosquitoes at the refuge through long-term habitat modification and mosquito control treatments. The channel creation work in the tidal marsh to eliminate mosquito breeding habitat is scheduled to begin in early summer 2014.

The Service evaluated and responded to comments received on the EAs. This information, the environmental assessments and more are available for review on the refuge’s mosquito web page www.fws.gov/oregoncoast/bandonmarsh/Mosquito.html.

Mosquito Control at Bandon Marsh NWR Will Move Forward
Bandon, Ore. - The U.S. Fish and Wildlife Service issued a final decision on its Integrated Marsh Management Approach to monitor and control mosquitoes at Bandon Marsh National Wildlife Refuge. The decision is based on the results of two environmental assessments that examined habitat modifications and the use of larvicides to control mosquitoes. The Service has issued Findings of No Significant Impact (FONSI) which describe the selected alternatives for both EAs.

Under the Supplemental Environmental Assessment for Tidal Marsh Restoration, the Service selected its preferred alternative (Alternative B). It will reduce mosquito breeding pools through improvement of tidal flow throughout the restored tidal marsh in the Ni-les’tun Unit of the Refuge. Eliminating mosquito habitat will prevent mosquito populations from expanding and will provide long-term control of mosquitoes. The work to expand the network of tidal channels is scheduled to begin in early summer 2014.

Under the Environmental Assessment for Mosquito Control, the Service selected Alternative B for implementation. Alternative B relies solely on the use of a naturally derived larvicide called Bacillus thuringiensis israelensis, or Bti, to control mosquitoes on the refuge. Bti targets mosquito larvae and is not toxic to bees, moths, butterflies, fish, mammals, or birds. Under this selected alternative the Service will not use synthetic chemical larvicides (e.g. methoprene and CocoBearTM) to reduce mosquitoes on the Refuge. After evaluating public comments collected between March 11 and April 9, 2014 and discussion with mosquito experts, the Service determined that using Bti will effectively control mosquitoes on the Ni-les'tun Unit while posing a low risk to wildlife, their habitats, and the human environment.

"Our long term goal at Bandon Marsh National Wildlife Refuge is to reduce mosquito breeding habitat, while also improving wildlife habitat on the Refuge," said Project Leader Roy Lowe. "To manage mosquito populations while those habitat modifications take place, Coos County Public Health will monitor mosquitos on the Refuge. They will treat with Bti when necessary to prevent larvae from hatching into adults and flying off of the refuge."

Monitoring, which began in early April and will continue throughout the summer, is a key component of the Integrated Marsh Management Approach. Results will be used to determine when and where to apply Bti. The Service expects this approach to minimize the number of adult mosquitoes being produced on the Refuge while using the least amount of larvicide necessary to accomplish the objective. Larvicide use will only occur on the Ni-les’tun Unit of the Refuge. The Service provided funding to Coos County Public Health to hire a field technician to monitor mosquitoes on the Refuge this season and to contract with Vector Disease Control, Inc. to apply Bti as needed on the Refuge.

"The Service will continue to coordinate closely with Coos County Public Health and Coos County Commissioners as we implement the Integrated Marsh Management Approach to mosquito control at Bandon Marsh National Wildlife Refuge," said Lowe.

Now that the final decision on the IMM Approach has been made, Coos County Public Health can begin mosquito control on the refuge when needed. The Service evaluated and responded to comments received on the EAs. This information, the EAs, FONSIs and more are available for review on the refuge’s mosquito web page www.fws.gov/oregoncoast/bandonmarsh/Mosquito.html. You can contact the Refuge through email at oregoncoast@fws.gov or call 541-867-4550.

Integrated Marsh Management Proposed for Bandon Marsh NWR
Bandon, Ore. - The U.S. Fish and Wildlife Service is asking the public to review and comment on the proposed Integrated Marsh Management approach at Bandon Marsh National Wildlife Refuge. The public review and comment period will begin on March 11, 2014 and end on April 9, 2014.

The actions proposed in the Draft Supplemental Environmental Assessment for Tidal Marsh Restoration will reduce mosquito breeding pools by improving tidal flow on the Ni-les'tun Unit of the refuge. The Draft Environmental Assessment for Mosquito Control for Bandon Marsh Refuge proposes utilizing larvicides, when necessary, to reduce larval mosquito populations on the Ni-les'tun Unit.

"Using habitat modification to greatly reduce mosquito breeding habitat is the primary and long-term approach for managing mosquitoes at the refuge," said Roy Lowe, Project Leader for the Oregon Coast National Wildlife Refuge Complex. "The Service is also proposing a short-term strategy to control mosquitos that includes the application of larvicide, which prevents mosquito larvae from becoming flying adults and has minimal negative environmental effects."

In addition to reducing the amount of mosquito breeding area, the Integrated Marsh Management approach will improve the tidally driven hydrology of the Ni-les'tun Unit of the refuge, benefiting wildlife including migratory ducks and shorebirds and anadromous fish such as juvenile coho salmon. The plan calls for increasing the amount of tidal channels in the marsh, which will allow for better tidal flushing. Tidal flushing happens with high tide each day and refreshes the saltwater in the marsh. Mosquito larvae require stagnant pools to complete their development, so increased tidal flushing will prevent the mosquito larvae from becoming flying adults.

"The Service is committed to continuing to work with the Coos County Public Health Department, Coos County Commissioners, members of Congress, and experts in the field of mosquito control to develop and implement the Integrated Marsh Management approach for Bandon Marsh National Wildlife Refuge," said Lowe.

The Service is inviting the public to attend an open house where you can ask questions and learn more about the Integrated Marsh Management approach. The open house will be held on Tuesday, March 18, 2014, at The Barn: Bandon’s Conference and Community Center, 1200 W. 11th St., SW, Bandon, Oregon, 97411. U.S. Fish and Wildlife Service staff and Coos County representatives will be available to answer questions anytime between 4:00 and 7:00 PM.

The draft EAs are available for download on the refuge website www.fws.gov/oregoncoast. Copies are also available in the reference sections of the public libraries in Bandon, Coquille, Coos Bay and North Bend. Printed copies can be obtained from the refuge by sending an email request to oregoncoast@fws.gov or calling (541) 867-4550. Comments can be mailed, faxed or emailed by April 9, 2014 to: Oregon Coast National Wildlife Refuge Complex, 2127 S.E. Marine Science Drive, Newport, OR 97365-5258; fax number (541) 867-4551; or e-mail oregoncoast@fws.gov. For more information please call the refuge office at 541-867-4550. The Service will evaluate and respond to the comments received in revised EAs and inform the public of our decision.
