Adaptive Cormorant Management up for Comment

lschultz • July 17, 2020

Double-crested cormorant (cormorant) management is once again at the center of agency rule-making with the U.S. Fish and Wildlife Service (USFWS) and MUCC is weighing in. 

Cormorants are a native species, but wreak havoc on fisheries populations across the Great Lakes region. To facilitate adaptive, localized management the USFWS submitted a proposed rule to the federal register to create a new depredation permit program that would allow state and tribal wildlife agencies to lethally control cormorants to protect wild and public hatchery-stocked fish. 

Michigan United Conservation Clubs (MUCC) is in strong support of adaptive cormorant management, per several member-passed resolutions. It is important that supporters of scientific wildlife management are heard in this comment process, as many of the others submitting comments represent animal rights organizations that oppose lethal management. MUCC Executive Director Amy Trotter submitted a letter to the USFWS encouraging the passage of this proposed rule. 

“The issues pertaining to the management of cormorants have been the subject of numerous policy resolutions from our members,” said Trotter. “All of these resolutions have focused on using a variety of tools to better bring the recovered population of cormorants in the Great Lakes into balance with other important wildlife and sportfish populations.”

Cormorants represent a remarkable conservation success story. From a species that was quite literally on the brink of extinction due to toxic pollution, they have far exceeded every goal for population recovery. The question about cormorants is not binary – we need not choose between either having cormorants or not – but wildlife managers must be equipped with the tools necessary to do their jobs based on the best available science. 

MUCC hopes that this new permit program will help state and tribal fish and wildlife agencies achieve a population of cormorants that will meet agency goals. 

Cormorants are a federally regulated fish-eating bird. According to USFWS Environmental Impact Studies, from the early 1970s to 2000 cormorant numbers increased from near zero to 115,000 birds in Michigan waters alone. Surveys suggest that current populations might number between 731,880 and 752,516 in the central and eastern United States. The majority of these cormorants reside in Lake Michigan and Lake Huron at some point in the year. Their diets consist mostly of alewives and round gobies (forage fish), but they also consume significant numbers of stocked trout and salmon fingerlings, as well as highly valued smallmouth bass and yellow perch. Although fisheries in 24 states in the central and eastern United States are affected by cormorant depredations, Michigan hosts about 55% of the interior population’s breeding pairs and can be considered “ground zero” for the negative effects of cormorants. 

Over the last twenty years, MUCC and our membership has continuously supported the need for cormorant control efforts. In 2002, MUCC passed a resolution supporting cormorant control that allows taking of cormorants, eggs and nests in order to significantly reduce the population, and supported removal from list of birds protected by the Migratory Bird Treaty Act. In 2004, MUCC passed a resolution urging the President, Congress, the Secretary of the Interior and USFWS to take the necessary action to provide appropriate funding support for double-crested cormorant control efforts, and to provide appropriate leadership, coordination, control and assessment of those efforts. Implemented over the last 12 years, these measures have been highly successful in reducing cormorant abundance to acceptable numbers and have restored our fisheries.

As always, MUCC will continue to track this proposal through the federal rule-making process, representing our members and all of the recreational anglers of Michigan. 

Since 1937, MUCC has united citizens to conserve, protect and enhance Michigan’s natural resources and outdoor heritage. MUCC has also been the constant protector of your rights to hunt, fish and trap since its founding. Please join us today: http://bit.ly/JoinMUCC

New Partnership: Certified Wildlife Habitat with National Wildlife Federation

By Olivia Triltsch • October 23, 2025
Michigan United Conservation Clubs (MUCC) is proud to announce a new partnership with the National Wildlife Federation (NWF) to bring the Certified Wildlife Habitat ™ program to communities across Michigan. This collaboration connects MUCC’s long-standing commitment to conservation with NWF’s national effort to create, restore, and certify habitats that provide food, water, cover, and places to raise young. Together, the organizations aim to inspire individuals, schools, and communities to take action in their own backyards to support native species. Through this initiative, MUCC will help expand awareness of the Certified Wildlife Habitat program, integrate it into its volunteer network, and provide resources to landowners interested in enhancing habitat on their property. One of the greatest benefits for volunteers comes from the knowledge gained in understanding wildlife habitat enhancement, allowing for the application to private land habitat enhancement. In addition to this, much of the work we do for habitat can apply to a variety of species, from rabbits to wood ducks, even birds of prey. The partnership will also promote community engagement opportunities through educational events, workshops, and collaborative restoration projects. In coordination with efforts like the certified wildlife habitat, MUCC hopes to expand conservation efforts across Michigan. Our award-winning, statewide volunteer habitat program, On the Ground (OTG), works to conserve, protect, and enhance wildlife habitat. In 2025 alone, OTG worked with 739 volunteers across 27 habitat projects, from invasive species removal to river clean-ups. Through the hard work contributing over 2,900 volunteer hours, habitat stewards were able to improve 423 acres of land for wildlife conservation in Michigan. Although OTG projects are not active year-round, we encourage Michigan residents to continue land stewardship on both public and private lands. To qualify for certification through the Certified Wildlife Habitat program, a property must include: Three natural food sources One water source Two places for shelter Two places to raise young Two sustainable practices To determine if your habitat qualifies, visit the NWF website and take the habitat quiz or download the checklist. If your habitat needs native plants, check out Garden for Wildlife to find species native to your area. The $25 application fee includes a personalized paper certificate, a 1-year NWF membership, and the option to purchase lawn plaques and garden flags. Habitats located on school grounds do not have a fee to get certified, so check to see what you might need to qualify today. If you are interested in joining our On the Ground program for the 2026 season, stay connected through our Facebook , Instagram , and OTG webpage for upcoming events.

On the Ground Junior: Fall Event Recap

By Olivia Triltsch • October 16, 2025
In 2025, the On the Ground program conducted 8 junior projects with schools involving 316 students from across the state. From tree plantings to invasive species removal, these students worked to enhance 39.3 acres of public land after contributing over 200 volunteer hours. Visit our website to learn more information about our On the Ground program and On the Ground Junior . To wrap up the 2025 field season, the On the Ground program worked with two classrooms to enhance wildlife habitat and recreational access. Junior programs like these allow teachers to get their students out of the classroom and into hands-on learning about the importance of habitat work while meeting individuals in the field.

October NRC Recap

By Justin Tomei • October 9, 2025
The Natural Resources Commission met today, Thursday, October 9th for their October meeting. The commission reaffirmed its intent to allow for lethal year-round coyote management on public and private land via a unanimously passed resolution before passing fisheries orders, and tabling more for consideration in November. The commission passed Fisheries Orders 210.26 , and 254.25 before tabling 206.26, 219.26 , and 253.26 . Commissioner John Walters provided an amendment to the fisheries order to expand underwater spearfishing opportunities to most of the Great Lakes, allowing for some spatial closures for the protection of particularly sensitive areas. The commission took steps to make good on their promise to allow year-round coyote management, unanimously passing a resolution more clearly stating their intent and what the pending wildlife conservation order will look like. The next meeting is Thursday November 6 in Lansing.
