Yale Developing New Lyme Vaccine

from Yale News

A vaccine for humans against Lyme disease is still at least a few years in the future, but Yale University may have come one step closer to solving the problem.

A vaccine released over 25 years ago was withdrawn from the market in 2002. The withdrawal was not for medical reasons but was based on low sales, and negative perception about vaccinations in general.

Researchers at Yale are working on a completely different type of vaccine. This will not target one particular strain of the tick-borne disease, but the new approach quickly responds to the presence of tick saliva. The vaccine targets 19 different proteins found in several species of ticks.

The vaccine uses the same mRNA technology that was used to quickly develop COVID-19 vaccines, which is totally different chemistry from traditional vaccines which are usually weakened strains of the disease.

As an analogy, the vaccine makes a tick bite more like a mosquito bite. If you are vaccinated and then are bitten, you will notice redness and itching right away and can remove the tick before it can transmit diseases. Tick saliva normally supresses the human immune response allowing the pathogen time to infect the host, but the vaccine stops that supression.

Tests are being conducted on guinea pigs which can develop Lyme disease. Early animal trials showed 100% protection across six major Borrelia strains over a full tick season. Human trials are still in the future.

Your Michigan Library Can Help You Get Off The Couch

Little Sable Light (photo by jhy)

by jhy

Wish you could visit some fun places around the state of Michigan but that it didn’t cost so much? The Library Network is here to help!

Just when we are hearing so many questions about the relevance of libraries in the digital age, we are presented with yet another good reason to love the local library.

MAP, the Michigan Activity Pass program, brings participating destinations and public libraries together to help people discover new cultural and recreational opportunities. Museums, public gardens, parks and more are already signed up. More venues are regularly being added. Each pass provides the user with a discount that can be applied to a portion of the fee.

What’s the catch? You have to have a Michigan Library Card. How do you get one? Go to the library, or the library web site, and sign up. No charge for that. There is no minimum age to obtain a library card, but children must have the consent of a parent or guardian. (And, of course, a library card is also a ticket to a world of discovery through books and visual media.)

Some participating locations nearby include Port of Ludington Maritime Museum, Historic White Pine Village, the Dennos Center in Traverse City, Big Sable Point Lighthouse, Little Sable Point Lighthouse and the Ludington North Breakwater Lighthouse. Lists from downstate include such well-known places as the Detroit Institute of the Arts, the Michigan Renaissance Festival at Holly, Hidden Lake Gardens, and many more. The Upper Peninsula is also well-represented.

All state parks and state forest campgrounds (not federal campgrounds) are part of the program. The savings vary by location. For example, at state forest campgrounds the discount can be used toward a campsite. At state parks, the discount applies to the entrance fee, but not for camping.

You can use one pass per library card every seven days, and once you request the pass you have seven days to use it before it expires. There is a complete list of options at miactivitypass.org including a map with filters that will allow you to search for participating venues within a specific radius of a particular location. The filters allow you to narrow the search if you only want certain results, such as children’s activities or art museums. Lists by region can also be found at tln.org (The Library Network).

For example, if a family has two adults who each have a library card, one pass could be used for a discount to camp at a state forest campground while a second pass could be applied toward a visit to an historical site.

To obtain the passes, start at miactivitypass.org. You will need to know your library card number(s), and if you aren’t sure of this, simply contact your local library. The passes can be printed from that site, or emailed to you or sent by text. It is up to the person requesting the pass to check on operating hours of the venue to be sure it will be open. A video tutorial is available at miactivitypass.org/resources-2.

The Library Network Michigan Activities Pass is a great way to increase your potential fun on a budget. Get off the couch and go get a library card and a pass to adventure.

Dragon Trail Flooding Damage

damage to Dragon Trail (photo from Michigan's Dragon at Hardy Dam)

from Michigan's Dragon at Hardy Dam

Dragon Trail Update 4/28/26: The Good, the Bad, and The Ugly!

The Good: 37 miles of the Dragon are rideable! Yea!

The Bad: There are a few areas, mostly drains and a few water saturated areas in that 37 miles. Expect to get dirty.

The Ugly: Section #7 is closed to users until catastrophic failures on the trail caused by the massive rainfall in early Aprilare repaired. There are side hills sliding downhill, washouts and tree root balls in the trail. There also are mudslides from uphill that cover the trail with MUD. The cycling group is working with the trail builder on corrective measures but they need time. Time to plan, time to dry out, time to organize. The best thing you can do now is be patient and stay out of section #7's closed area. Please don't be that person who ignores the trail closed sign and adds to the problems!

Volunteer trail days will be scheduled as soon as the plan is in place. Thanks!

Lower Michigan's Topography

elevation map of Lower Michigan (map from muir-way.com)

from Michigan Trout Streams

Northern Michigan’s landscape is basically a frozen moment of the last ice age thawing out. What you see today—rolling hills, sandy soils, clear rivers, and thousands of lakes—was shaped almost entirely by the advance and retreat of massive continental glaciers during the Wisconsin Glaciation about 75,000 to 11,000 years ago.

Instead of sharp mountains, northern Michigan has a softer, sculpted terrain:
• Moraines: Ridges of rock and debris pushed up by glaciers. These form many of the region’s hills and divides.
• Outwash plains: Flat, sandy areas where meltwater spread sediments—these are why so many northern rivers run over gravel beds.
• Kettle depressions: When buried ice chunks melted, they left behind holes that became lakes and wetlands.
• Drumlins: Long, streamlined hills shaped by moving ice, common in parts of the Lower Peninsula. This mix gives northern Michigan its “rolling” feel—nothing extreme, but constantly changing elevation.

Michigan’s lakes weren’t just filled in—they were carved out:
• As glaciers advanced, they scoured and deepened basins in softer bedrock.
• When they melted, those basins filled with water, forming inland lakes and contributing to the Great Lakes system.
• Many smaller lakes are kettle lakes—steep-sided and surprisingly deep for their size. That’s why you’ll find clusters of lakes in places like the inland areas around Petoskey and Gaylord.

Rivers in northern Michigan are direct products of glacial meltwater:
• As glaciers retreated, huge volumes of water carved channels through loose sand and gravel.
• These channels became today’s rivers, often following winding, natural paths rather than straight lines.
• Because the substrate is porous, groundwater feeds many rivers, keeping them cold, clear, and stable in flow—ideal for trout.

Several good trout rivers:
• Au Sable River – formed through outwash plains, known for steady flow and sandy bottom sections.
• Manistee River – a mix of glacial valleys and groundwater influence.
• Jordan River – tighter valley, more direct glacial carving, colder and more confined.

Glacial geology still controls how these rivers behave:
• Cold groundwater inputs → consistent temperatures (perfect for trout)
• Gravel and sand bottoms → ideal spawning habitat
• Meandering channels → create pools, riffles, and habitat diversity
• Wetlands and headwaters → act like sponges, regulating flow

In short, northern Michigan’s rivers aren’t accidental—they’re the lingering fingerprints of melting ice. The same forces that flattened mountains elsewhere created one of the most stable, trout-friendly river systems in the country.

Grandville to Increase Pedestrian Friendliness

Chicago Avenue project (photo from Beckett & Raeder)

from several sources

The City of Grandville, Michigan, is transforming the east end of Chicago Drive into a pedestrian-friendly, mixed-use space, featuring "road diet" traffic calming, new sidewalks, and improved public areas. This initiative aims to extend the vibrant downtown atmosphere eastward, enhancing safety and aesthetics.

The street has been oriented solely for vehicular use. Pedestrians and cyclists were at risk. The Chicago Drive Streetscape Project will dramatically change the aesthetic quality of the area.

Four traffic lanes will be cut to two with a center turn lane. Parking, crosswalk bump-outs and widened sidewalks are more welcoming to non-motorized users. The sidewalks will be buffered from traffic by planters, street trees, and the parking lane. Benches and bicycle racks have been added.

Completion will probably be in the fall of 2026.

a news release of Michigan DNR

Get text tips on birding hot spots!

A male mourning warbler, with a bright yellow body and bluish-purple head, perches on a thin, rust-colored branch, Marquette County, Michigan.

Michiganders know spring is one of the best times for birding! Early-season migrating species are hunkering down to make and raise their families, while other birds are dotting the skies with brilliant colors as they scout for nesting places.

Whether you're a veteran birding enthusiast or brand new to this popular pastime, you're in good company: A recent Audubon article cites a U.S. Fish and Wildlife Service report that shows the U.S. is home to an estimated 96 million birders in the United States — more than a third of U.S. adults!

Everyone can take advantage of the DNR's Winged Wednesday texts that provide updates on birds being spotted in state parks, state wildlife areas and other places around the state. A new bird and new park are highlighted each week, an easy encouragement to help birders build meaningful connections to this lifelong pursuit.

Maia Turek, engagement and innovations specialist for the DNR Parks and Recreation Division, said more than 5,000 people currently are subscribed to receive the text messages each Wednesday.

"The program actually started with the intent of getting seniors out of their homes post-COVID for 30 minutes a day to help prevent isolation, which was a secondary pandemic at the time," Turek said. "Now, Winged Wednesday texts are really for anybody who’s interested in finding new places to explore birds doing amazing bird things."

Ready to get started? Text BIRD to 51555 or sign up online for Winged Wednesday weekly text updates. Learn more at Michigan.gov/Birding. Questions? Contact Maia Turek at 989-225-8573.

New Threat from Balsam Wooly Adelgid in Michigan

balsam wooly adelgid (photo from USDA Forest Service)

from Michigan DNR

Balsam woolly adelgid can infest true fir trees, including balsam, Fraser and concolor (white) fir in forests and landscapes in Michigan. Balsam fir can be found in conifer and mixed hardwood/conifer forests of Michigan's Upper and Northern Lower peninsulas. Unlike hemlock wooly adelgid, there are many more obvious symptoms of infected trees including loss of crown needles, swollen twigs, and white scale on the bark in addition to the small white eggs around the needles.

Balsam woolly adelgid is a sap-feeding insect that attacks true fir trees, including balsam, concolor (white) and Fraser fir. Repeated attacks weaken trees, cause twig gouting, kills branches and, over the course of several years, cause trees to die. There are nearly 1.9 billion balsam fir trees in Michigan's forests. As the third largest Christmas tree-growing state in the country, Michigan produces nearly 13.5 million fir trees each year, grown on over 11,500 acres. True fir trees, including forest, landscape and Christmas trees, are susceptible.

Balsam woolly adelgid can be introduced on infested nursery stock, Christmas trees, firewood or tree products. Though the insects don't move far on their own, they can be carried by wind, wildlife, humans or vehicles to new locations.

Adelges piceae (Ratzeburg), an invasive sap-feeding insect, were identified in lower Michigan in fall 2023. This tiny insect is native to Europe but has probably been introduced into North America multiple times.

Balsam wooly adelgid was found in 2023 Missaukee County. Since then, more infestations of BWA have been identified on balsam fir in forests in Missaukee and Clare counties. Osceola County, Marion Township is also subject to quarantine.

EXTRA- Pine River Safety Alert

graphic from Manistee National Forest

a news release of Manistee National Forest

The Huron-Manistee National Forests is strongly cautioning anglers and paddlers to consider not navigating the waters of the Pine River this weekend.

A massive logjam between Peterson's Bridge and Low Bridge River Accesses has made navigation dangerous in the swift moving waters. Logjams were also reported at Dobson Bridge upstream from Peterson's Bridge. Logjams also pose additional risks to river recreation users.

• Water passing through logjams traps solid objects, posing higher drowning risks for kayakers and canoers.
• Redirect water flow, often causing intense erosion on stream banks, which can lead to unstable banks.
• Accumulated debris can block bridges and culverts, triggering severe flooding, forcing water onto roads sometimes causing them to fail.
• Portage can become difficult or impossible.
• Flow of water can be at a higher velocity.
• Potential to have watercraft puncture by submersed debris.
• Surfaces with heavy silt or sand can be water saturated and react like quicksand.

Highlights of North Country Trail Annual Report

cover of NCTA 2025 Annual Report

from the NCTA

The North Country Trail Association has issued their 2025 Annual Report which helps people see at a glance what has been accomplished over the past year.

If anyone has reservations about the how their contributions are being used, this should make you proud to support the trail. There are 618 miles of the 4800-mile trail in Lower Michigan.

Highlights from 2025:
• total miles of NCT - 4860
• 53 bridges built or replaced
• 4066 feet of puncheon built or replaced
• of the 4860 trail miles, 3365 are now off road (70% off road, and more miles off road than the original estimate for the entire trail

Concerning finances, the report states: "The NCTA continued remarkable financial sustainability in 2025. Despite a 22% decline in agency grants and early uncertainty about federal funding, which accounts for roughly 20 to 25% of revenue, strategic “belt-tightening” ensured a resilient bottom line. Growth was fueled by a record-breaking year for private support: Donations and memberships hit $900,000 (up 20%), while corporate and foundation giving rose by 23%. These resources were immediately mobilized for the trail"

NCTA Board President Jan Ulferts-Stewart says, "This report features work that honors our history as a volunteer-powered organization while positioning us to reach even further in the years ahead. Thank you for your role in caring for the North Country Trail and ensuring it remains a place of pride. "

Petoskey Moves to Preserve Little Traverse Wheelway

collapsed Little Traverse Wheelway (photo from City of Petoskey Parks and Recreation))

from Bridge Michigan

The Petoskey City Council says it intends to preserve public trail easements along the Little Traverse Wheelway. The damaged section of what is known as the "Miracle Mile," is an easement across private property.

Owners, Gustav and Courtney Lo, have sued Petoskey for not repairing damaged sections of the trail that fall on their land. They want the easement released back to them saying that the lack of maintenance makes this necessary.

The city has instructed its attorney to continue to negotiate to maintain the easements. However, the major stumbling block is the $20 million price tag to rebuild and stabilize the shoreline that collapsed from erosion in 2020.

Public input strongly supports protecting the trail, but the funds will be difficult to raise under possible time constraints of the Los' lawsuit.

After a closed session of the council on April 20, Mayor John Murphy read the following statement: “It’s the city council’s intention to preserve the easements of the trail. The city council has authorized the city attorney to continue in discussions with the Los with a goal, with the intent to preserve existing easements while addressing the Los’ concerns.”
