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.

Paddle Siletz Bay Wildlife Refuge
The U.S. Fish and Wildlife Service invites you to explore Siletz Bay National Wildlife Refuge with a series of twelve guided canoe and kayak trips during June, July, and August 2014. During these trips visitors will spend about two hours paddling through the heart of Siletz Bay Refuge while learning about its wildlife and natural history.
Participants must provide their own canoe or kayak for each trip. If you don't have one available, they can be rented from the Siletz Moorage or other venues in the Lincoln City area. During the summer, the area of Siletz River nearest the mouth of the bay often has unpredictable winds and waves. For this reason we do not recommend this paddle trip for beginners, experience is strongly recommended. For your safety please dress appropriately for paddling in all weather conditions. Wearing a personal flotation device (PFD) is mandatory.
The U.S. Fish and Wildlife Service can provide binoculars, field guides, and PFD’s to use during the trip if needed. Trips are limited in size, and scheduled on a first-come first-serve basis; therefore, you must call or e-mail ahead to make a reservation. Please include the amount of boats in your party when making the reservation. Once you are registered, we will send out additional information regarding the trips. All trips will launch within 15 minutes of the time listed. Visit our website for updates and space availability www.fws.gov/oregoncoast/calendar.

Siletz Bay is one of the estuaries located along the Pacific Coast Scenic Byway. On either side of Highway 101, starched skeleton trees jut forth from the estuary and are reminiscent of a time when the salt marsh was diked for pasture. Osprey, Red-tailed Hawk, and occasionally Bald Eagle can be seen roosting at the top of these snags. A variety of estuarine dependent birds including Great Blue Heron, Great Egret, and some species of waterfowl can be seen foraging in the tidally influenced waters. The refuge also provides nursery grounds for Coho and Chinook salmon, steelhead, and cutthroat trout. Don’t miss your chance to participate in our interpretive paddle tour of Siletz Bay Refuge!

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.
