August 31, 2017 Phragmites Treatment along the Saginaw Bay Shoreline Area:
Treatments to control dense infestations of the invasive weed Phragmites will be done in the next week when weather conditions improve and are favorable for the treatment.  The weather parameters for treatment include winds less than 10 miles per hour and less than 40% chance of rain within 6 hours of treatment so these conditions will dictate the exact date and time of treatment.

2016 Treatment of Phragmites Along Saginaw Bay Shoreline Area

Treatments to control dense infestations of the invasive weed Phragmites were done done  in the fall of 2016 along the Saginaw Bayshoreline in Arenac, Bay and Tuscola counties.  This aerial spray treatment for Phragmites was done by Hamilton Helicopters, Inc. of Hamilton, Michigan; (616)291-5808. 

Phragmites treatment was done with a mixtureof the products Aqua Neat and Habitat which are aquatic formulations of the pesticide

Glyphosateand Imazapyr. These are non-selectiveherbicides that can cause damage to any plant that they contact. People and pets should avoid contact withthe treated areas until spray solution has dried (approximately 6 hours) toprevent transfer of the spray product onto desirable vegetation. Surface (lake) water in treatment areasshould not be used for irrigation for at least 24 hours after treatment.

PRESS RELEASE -DNR,DEQ, MDARD to host outreach events at boat launches during Aquatic InvasiveSpecies Awareness Week (June 29, 2016)

Gov. Rick Snyder hasproclaimed July 3-9 as Aquatic Invasive Species Awareness Week in Michigan, andstate departments are observing the week with outreach events at more than 50boat launches statewide.  AIS are non-native aquatic plants and animals that disrupt the naturalecosystem, tourism and the economy.  The week is highlighted by the third annual AIS Landing Blitz, an outreachevent for boaters held at boat landings around the state. The DEQ is partneringwith local volunteers as well as the Department of Natural Resources andDepartment of Agriculture and Rural Development to assist boaters in preventingthe spread of these harmful species and complying with current AIS-relatedlaws.  With recent discoveries of invasive New Zealand mudsnails in the Au Sable andPere Marquette rivers, the week takes on an added importance. Many invasivespecies, including New Zealand mudsnails, are easily spread by boaters andanglers using their equipment in multiple bodies of water without properlycleaning it.  Anyone enjoying Michigan’s waters can take action to prevent the spread ofaquatic invasive species by following these simple steps:

Required Actions – It’sthe Law in Michigan!

  • Remove aquatic plants from boats, boating equipment and boat trailers before launching or placing in the water.
  • Drain live wells, bilges and all water from boats before leaving the access site.
  • Dispose of unused bait in the trash. Do not release bait into the water.
  • Don’t transfer fish to water bodies other than where they were caught.

Recommended Actions –Protect Our Waters!

  • Inspect and remove plants and mud from boats and trailers and dry equipment before leaving the access area. Dispose of the material in a trash receptacle or otherwise away from the water body if possible.
  • Wash boats and trailers before leaving the access area if possible, or at a nearby car wash or at home.
  • Dry boats and equipment for at least five days before launching into a different body of water.
  • Disinfect live wells and bilges with bleach solution of 1/2 cup bleach to 5 gallons of water.

The Great Lakes andMichigan’s inland waters draw millions of recreational users and touristsannually, and already face negative impacts from numerous aquatic invasive species.Preventing the introduction of further invasive species is a responsibility foreveryone who uses these resources.  Events at boat launches are contingent on weather and local volunteeravailability. For an up-to-date list of events, contact Kevin Walters at517-284-5473 or  AIS Awareness Week is sponsored by the DEQ’s Water Resources Division with collaborativeefforts from other state and federal agencies as well as private and nonprofitorganizations.
