DNR Offers Free Exotic Aquatic Plant Watch Training

The Michigan Department of Natural Resources is searching for residents who want to learn about exotic aquatic invasive plants, and to maybe even become a volunteer to help preserve our lakes.

Aquatic invasive plants have their own summer travel plans and are finding their way into lakes across Michigan.

According to the DNR, once they arrive in a lake, they can become established before anyone is even aware of their presence.

From there, it can be difficult and costly to manage.

Early detection of invasive plants gives the best opportunity to keep them in check through targeted management.

Knowing which aquatic invasive plants are in your lake, can help raise awareness among all lake users about the need to clean, drain and dry boats before visiting different lakes.

If you’re concerned about aquatic invasive plants, the DNR suggests considering to become an exotic aquatic plant watch volunteer.

This is part of Michigan’s Cooperative Lakes Monitoring Program.

DNR to hold series of public meetings on starry stonewort

MADISON, Wis. – The Wisconsin Department of Natural Resources will hold a series of public meetings in southeast Wisconsin to share information about starry stonewort and answer questions from area lake organizations and interested community members.

The first meeting will be held on July 29 with additional meetings to be scheduled around the region.

Starry stonewort, which arrived from Eurasia and was first discovered in the U.S. in the St. Lawrence River in 1978, has now been confirmed in Long Lake in Racine County and Silver Lake in Washington County as well as the previously reported findings in Little Muskego Lake, Big Muskego Lake and Bass Bay in Waukesha County, said Carroll Schaal, DNR lakes and rivers section chief. Starry stonewort, also found in Michigan, Indiana and the northeastern U.S., can form dense lakebed mats that crowd out native plants and eliminate habitat for juvenile fish.

The series of meetings will present information on the biology of starry stonewort, its current status and monitoring and management efforts. The audience will learn about actions that can help prevent the spread and what lake residents can do to help monitor and control it.

The first informational meeting will be held July 29 from 6 to 8 p.m. at the DNR Waukesha Service Center, 141 NW Barstow St., Room 151. Additional meetings will be announced at a later date. To learn more about starry stonewort, visit, and search for “aquatic invasive species.”

Protect lakes, rivers; stop aquatic hitchhikers

July 08, 2015 8:00 am

As you head out this summer and enjoy Wisconsin’s beautiful lakes and rivers, please remember that the DNR needs your help in preventing the spread of aquatic invasive species.

Aquatic invasive species are nonnative plants and animals that can have a negative impact on the state’s lakes and rivers and cause ecological and economic harm. Aquatic invasive species are spread by hitching rides on boats, trailers and other equipment that is transported from one body of water to another.

While some bodies of water in Wisconsin already have aquatic invasive species present, a majority of the state’s waters have not been infested. To help contain and control aquatic invasive species in infested waters and prevent their spread to waters not yet infested, please remember to follow the Wisconsin Aquatic Invasive Species Laws every time you enjoy the state’s lakes and rivers.

It’s the law to:

  • Inspect your boat, trailer and equipment.
  • Remove any attached aquatic plants or animals (before launching, after loading and before transporting on a public highway).
  • Drain all water from boats, motors and all equipment.
  • Never move live fish away from a waterbody.
  • Dispose of unwanted bait in the trash.
  • Buy minnows from a Wisconsin bait dealer. You may take leftover minnows away from any state water and use them again on that same water. You may use leftover minnows on other waters only if no lake or river water, or other fish were added to their container.
  • For additional information on aquatic invasive species, visit or contact DNR Water Guard Meghan Wall at 608-518-1015 or

Aquatic invasive species the focus of awareness week.

Posted: Thursday, June 25, 2015 12:18 pm

MICHIGAN — Asian carp and other invasive species found in the water continue to threaten Michigan and environmental organizations hope to spread awareness during Aquatic Invasive Species Awareness Week.

Michigan Gov. Rick Snyder proclaimed the week of June 28-July 4 Aquatic Invasice Species Awareness Week with the goal of helping make Michigan residents aware of the threat Asian carp and other species pose to the Great Lakes and other Michigan waters, and inform residents of the need to take action to prevent or control the introduction and spread of these species.

In a press release, distributed by the Michigan Department of Natural Resources (DNR), on behalf of the Michigan Department of Environmental Quality (DEQ), aquatic invasive species are defined as non-native organisms that establish themselves outside of their normal range, intentionally or unintentiaonally.

When introduced to these new locations, like lakes, rivers and wetlands, they can harm the location, as well as species inhabiting the area.

Featured during Aquatic Invasive Species Awareness Week is the second annual Aquatic Invasive Species Landing Blitz. Through this program aimed toward boaters, the DEQ, DNR and Michigan Department of Agriculture and Rural Development will all partner together with volunteers to help boaters in stopping the spread of aquatic invasive species and assuring compliance with laws in place to prevent the spread.

The Landing Blitz will occur at 45 boat landings around the state.

Some of the laws and actions to prevent the spread of invasive species, as required by the state, include:

• Remove aquatic plants from boats, boating equipment and trailers before placing the boat 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 in the water.

• Do not transfer fish to water bodies other than where they were caught.

Though anglers are not required by law to follow them, a series of recommended actions have also been compiled to help prevent the spread of aquatic invasive species, including:

• Inspect and remove plants and mud from boats, trailers, gear and dry equipment before leaving the access site. Dispose of these materials in a trash receptacle or other means away from the water body.

• Wash boats, trailers and other equipment before leaving the access area, if possible, or at a nearby car wash or at home.

• Allow boats and equipment to dry for at least five days before launching boat into a different body of water.

• Disinfect live wells, bilges and other equipment with a solution made of approximately a half cup of bleach and up to five gallons of water.

These additional invasive species awareness events come as Michigan waters face threats from several invasive species, including two Asian carp species and a number of aquatic plants.

Michigan’s inland waters and the Great Lakes attract millions of visitors annually and with 180 invasive species found in the region already, it is important to prevent the spread and introduction of additional species.

Summer heat can cause algae blooms.

The first five and a half months of this year have seen the temperatures in our area stay on the cooler side of the seasonal spectrum, but here in the last couple weeks we’ve had more days than not break the 90-degree bubble.

For people who lamented the below-zero thermometer readings and enjoy soaking up the sun, this has been a welcome change, but for others, myself included, I’d trade the sticky summer sauna for a crisp fall day in a heartbeat.

Sun-loving humans aren’t the only ones enjoying this climatic shift. If you own a pond or live near a lake, you have undoubtedly noticed a change in the aquatic ecosystems from all this warm weather. The summer heat coupled with longer days and the large amount of rainfall we’ve experienced have created the perfect conditions for algae and aquatic plant growth, and I have received several calls recently regarding this sudden explosion of growth.

Most aquatic plants start reaching maximum growth potential once water temperatures rise above 70 degrees or so, and the recent storms have carried a lot of nutrients off lawns and fields into bodies of water. Fertilizer for your grass has the same effect on aquatic plants if it enters a pond or lake, so when we get runoff from heavy rains, this can lead to explosive algae blooms.

Lake Erie and Buckeye Lake are in the news quite frequently when blooms of cyanobacteria, commonly referred to as blue-green algae, can lead to harmful levels of the microcystin toxin in the water. This toxin can be harmful to humans and animals if the concentration reaches a high enough level, but luckily this occurs primarily in large, nutrient-rich bodies of water and is not very common in small private ponds and lakes.

Most problems homeowners face are caused by true aquatic plants or the ubiquitous filamentous algae that can form the mats of floating “moss” that plague fishermen and swimmers every summer. Another common problem that creates concern among pond owners is often an infestation of duckweed and watermeal that will completely cover a pond’s surface and create a “scummy” look from a distance. Both of these issues can be unsightly and create problems for aquatic life, but pose no health threat to humans.

Additionally, there are a host of other aquatic plants, both submergent and emergent, that can detract from aesthetics and water quality that often pop up in the summer months. While a certain level of aquatic vegetation is beneficial to fish and other aquatic life, too much growth can not only restrict use of the water body, but also can lead to oxygen crashes and fish kills.

I frequently make site visits to ponds around the county this time of year when landowners experience problems with aquatic vegetation. This service is available for anyone in the county and appointments can be made by contacting me at the Soil and Water office.

State announces $3.6 million in available grant funding to
combat invasive species in Michigan

Funding proposals for 2015 are now being accepted through the Michigan Invasive Species Grant Program, with an anticipated $3.6 million available to applicants. The program – a joint effort of the Michigan departments of Natural Resources, Environmental Quality and Agriculture and Rural Development – is part of a statewide initiative launched in 2014 to help prevent and control invasive species in Michigan.

The 2015 grant program handbook outlining focus areas and information on how to apply is available on the DNR website The Michigan Invasive Species Grant Program supports projects throughout the state that prevent, detect, manage and eradicate invasive species on the ground and in the water. Total grant funding is set by the Legislature and the governor during the annual budget cycle.

Administered by the DNR, the Michigan Invasive Species Grant Program targets four key objectives:

  • Preventing new introductions of invasive species through outreach and education.
  • Monitoring for new invasive species as well as expansions of current invasive species.
  • Managing and controlling key colonized species in a strategic manner.
  • Responding to and conducting eradication efforts for new findings and range expansions.

“These grants offer a great opportunity to expand crucial efforts to battle invasive species in Michigan’s woods and waters,” said DNR Director Keith Creagh.

“Partnerships like this are vital to protecting our world-class natural resources,” Creagh added. “There is an enormous need to work together to address invasive species in our state, and just as big a willingness by residents, agencies and other stakeholders to get the job done. This grant funding will go a long way toward achieving that success.”

Local, federal and tribal units of government, nonprofit organizations and universities may apply for funding to support invasive species projects conducted in Michigan.  For this 2015 funding cycle, pre-proposals will be accepted through July 31 and requested full proposals are due by Oct. 30.

Grant requests for 2015 projects can range from a minimum of $25,000 to a maximum of $400,000. Applicants must commit to provide at least 10 percent of the total project cost in the form of a local match. Proposals with match levels above 10 percent will receive higher ranking.

Competitive applications will outline clear objectives, propose significant ecological benefits, demonstrate diverse collaboration and show strong community support.

2014 grant funding outcomes In 2014, the Michigan Invasive Species Grant Program provided more than $4 million to fund 19 projects including the development or expansion of Cooperative Invasive Species Management Areas, which now operate in 66 of Michigan’s 83 counties. These cooperatives detect, map and manage invasive phragmites, Japanese and giant knotweed, flowering rush and other non-native species that can cause economic or environmental harm. Additional awards focused on:

  • Finding new approaches to treating aquatic invasive plants.
  • Reducing the spread of oak wilt and preventing new forest invaders.
  • Raising public awareness and participation in identifying and reporting invasive species.

Informational grant workshops in June and July
Those interested in undertaking invasive species projects in Michigan and considering applying for a grant are encouraged to attend one of four upcoming workshops scheduled in Mackinaw City (June 25), Munising (June 26), Hastings (June 30) and Detroit (July 7).

Attendees will learn about program goals, 2015 focus areas, applicant eligibility and the application procedure. Optional discussion sessions to help connect groups interested in developing Cooperative Invasive Species Management Areas will be held following the workshops at the two southern Michigan locations.

MI: Aquatic invader, European Frogbit, affected by shading treatments

New York study suggests non-chemical shading treatments can reduce plant biomass of European Frogbit (Hydrocharis morsus-ranae L.).

According to the Midwest Invasive Species Information Network, the occurrence of the invasive aquatic plant known as European Frog-bit has so far been limited to the east side of our state. The discovery of a Frog-bit infestation in Alpena in 2013 is detailed in a previous Michigan State University Extension article.

Resembling a small water lily, European Frog-bit is an attractive aquatic plant and a favorite of water gardeners. It grows in a dense mat and can out compete native plants for space and light. As there is no aquatic herbicide proven safe and effective in the treatment of this escapee other control measures must be explored. Researchers in New York published a study in June 2014 detailing their investigation of the use of shade as a possible control measure.

Previous studies have shown that, like many plants, European Frog-bit is dependent upon light for growth and light-deprivation may significantly reduce plant biomass. This research project was conducted in a greenhouse (under controlled temperature and light conditions) and also in a sheltered inlet on Oneida Lake – one of the New York Finger Lakes. Plants were covered with a range of densities of shade cloth to block out some or all light.

Results of the New York study indicated that, under greenhouse conditions, 50 percent or greater shading affected frog-bit growth and no plants survived at 100 percent shading levels. Results of the in-lake study indicated that biomass was significantly reduced by 70 percent or greater shading. Overall, the effects of shading on in-lake water temperatures, dissolved oxygen and existing submerged plant communities were varied.

For a more in-depth summary of the New York study findings, along with a link to the full study, please visit the Lake Scientist website. A handy boater’s guide to selected aquatic invasive plants is available from Michigan State University Extension.
