Michigan’s Department of Agriculture and Rural Development says the spread of hemlock woolly adelgid along Lake Michigan is increasing. Native to East Asia, hemlock woolly adelgid is an invasive insect that attacks Hemlock trees, feeding on their sap and killing them between 4 and 10 years of infestation.

According to the MDARD, it’s been detected in Allegan, Antrim, Benzie, Leelanau, Manistee, Mason, Muskegon, Oceana, Ottawa, Van Buren, and Washtenaw counties. 

Rob Miller is the Michigan’s Department of Agriculture and Rural Development’s (MDARD) invasive species prevention and response specialist. Miller has played a crucial role in slowing the insect’s spread across the state. 

“Hemlock woolly adelgid really became a problem… between 2015 and 2017. It was [unintentionally] brought into the state on nursery stock that was infested with hemlock woolly adelgid [and] there are no native predators or diseases to keep [their] populations in check,” Miller says. 

While infestations have been found at the University of Michigan’s Nichols Arboretum, Miller is not overly concerned for Southeast Michigan. He says Southeast Michigan’s climate isn’t suited for hemlock trees, so the area doesn’t have a large population of them to worry about.

However, Miller is very concerned for the infestations detected in the west and northern regions of Michigan’s Lower Peninsula, where there are hundreds of hemlock trees. 

Treatment for hemlock woolly adelgid 

Unfortunately, Miller says the infestation is too far along and too widespread for eradication to be an option for MDARD. One way the state  is supporting this effort is by funding local conservation districts that have Cooperative, Invasive Species Management Area (CISMA) programs. Miller says this partnership gives local conservation districts more resources to directly treat and prevent hemlock woolly adelgid infestations. 

For property owners, there are two different insecticides to treat hemlock woolly adelgid infestations: imidacloprid and dinotefuran. 

Miller differentiates these chemicals by the speed they move through trees; imidacloprid moves slowly and protects the tree for longer, and dinotefuran moves quicker and protects the tree for a couple of years. 

Both insecticides are neonioctinoids, which are harmful among pollinators. However, Miller explains that application techniques reduces the environmental risk of these chemicals.

“You’re applying [insecticide to protect hemlock trees] either directly to the trunk of the tree or you’re actually injecting it in the tree. You’re not spraying it all over the place…shooting it out of a high pressure hose [or] using a mist system,” he says.”

“So, when it’s applied to the tree properly, it’s very targeted and that chemical is then actually inside the tree, and we don’t have any runoff.”

Public access to the Wayne County Airport Authority’s monthly meetings has changed, according to officials and an inside source. The move follows public opposition to the use of Willow Run Airport by Immigration and Customs Enforcement (ICE) deportation-related flights earlier this year.

In February, the WCAA ended an option for the public to attend monthly meetings remotely while keeping the option available for some employees.

Officials say the decision to end remote attendance is meant to prioritize those who attend the meeting in-person and is a part of a broader shift to the Authority’s pre-pandemic policy. However, an inside source says the change is a reaction to strong public opposition against the use of Willow Run Airport for ICE deportation flights.

An anonymous whistleblower shared internal communication with WDET that shows while the public will be barred from attending public meetings remotely, some employees will still be offered the option. Those employees must first be vetted by the officials before receiving a unique, traceable link to attend. 

The source also tells WDET that public comment had previously been moved to the end of each monthly meeting, raising concerns that the change will limit public input before major decisions are made. 

Under the Freedom of Information Act, WDET requested all flight activity records, agreements, contracts, communications, and financial records related to the use of Willow Run Airport by ICE.

The airport authority is charging WDET $7,991.68 for the information.

Tensions erupted at the Oakland County Board of Commissioners meeting as residents objected to the approval of a controversial Flock surveillance contract.

Public comment was halted after the crowd began calling for the recall of Board Chair Dave Woodward. WXYZ found that he visited Flock Safety’s headquarters last fall, a trip paid for by the surveillance company that he did not disclose prior to voting on the contract.

West Bloomfield resident Ellie Mosher said speakers were skipped during the comment period, prompting outcry from attendees before Woodward called a recess.

Residents attending the meeting already have reason to feel unheard. “They have had meetings regarding budgets that we are not have access to. That is not public record when it very much should be,” said Mosher.

Mosher is worried about Oakland County becoming a surveillance state with Flock cameras. “We’re seeing them pop up more and more. They can record. They use infrared light to be able to see at night, see license plates, see people’s faces through sunglasses, through clothing, through hats.”

This disruption follows criticism of a previous meeting where residents say commissioners approved Flock surveillance drones before allowing public input.

Activists in Ypsilanti Township keep fighting to halt a data center development associated with nuclear weapons research.

Stop the Data Center members gathered following an anonymous tip about a potential groundbreaking ceremony in South Hydro Park in Ypsi Township. So far, construction details for the $1.2 billion data center have been kept under wraps by University of Michigan and Los Alamos National Laboratory officials. 

Elizabeth Jordan is a spokesperson with Stop the Data Center. She says the facility will have several buildings, including one for nuclear weapons research that will need so much energy that a new DTE substation will need to be built on location. 

“One of the buildings will account for 10% of the energy, serving as a small data center for University of Michigan to lease, while the remaining 90% will power a much larger, top-secret military data center authorized for Los Alamos to conduct nuclear weapons research,” says Jordan.

Local officials are also against the data center’s construction in Ypsilanti Township. Jordan says the political influence of the University of Michigan could move the project forward despite existing zoning restrictions and widespread local opposition. 

Jordan says Stop the Data will continue to monitor the site closely, and host monthly public meetings. 

“[Stop the Data Center] is on Instagram…we also have big monthly meetings. The next one is May 9 at 2 p.m… it’s in North Hydro Park, right across the river,” Jordan says. 

The U.S. Forest Service is shutting down all four of its research centers in Michigan as part of a nationwide reorganization, sparking concerns about the future health of forests in the Great Lakes.

According to environmental advocates, the closure could increase problems like invasive pests and diseases, as well as harm wildlife, outdoor recreation, and forest biomes. 

Emma Shedd is with the Sierra Club’s Michigan Chapter. She says the importance of these research centers cannot be ignored.

“It is a big deal….there are a lot of impacts that we can expect to see [like layoffs and loss of skilled research staff]…we can [also] expect to see a much weaker agency, and that trickles down to a lack of regional research to support our forests here [in Michigan].” 

Researchers with the U.S. Forest Service study forest health, monitor invasive species, and collect long-term data that help both federal and state agencies make decisions. Shedd says this includes a nationwide program which guides actions about logging, wildlife habitats, water quality, and outdoor activities.

Without these facilities, she says, a lot of that work could be reduced or lost. 

Shedd says, “Forest management is a long term game…we’ve got rotations of 60 to 80 to 100 years going on in our forest, and so having a lack of management now…has effects that span whole lifetimes.” 

She says Michigan residents who oppose the drastic cuts to the U.S. Forest Service should call their representatives. “This is something that we really need to push back on for… the health of our forests in the long term,” Shedd says.
