Researchers in the Michigamme Highlands observed a 64 percent survival rate among moose calves born in May and June 2026. This rate, based on tracking 22 radio-collared calves through September 2026, indicates positive growth potential for the state's moose population.
Why it matters
Understanding calf survival is essential for determining why Michigan's moose population has remained at several hundred animals despite historical reintroduction efforts. Tracking these survival rates helps biologists manage the population as it works toward a long-term goal of 1,000 animals.
Of the 22 calves tracked in 2026, 14 survived, exceeding the 50 percent threshold researchers consider healthy. This study focuses on the population currently estimated at approximately 300 animals, following a 2023 survey that counted 426 animals in the core area.
The players
Michigamme Highlands
A remote forest region serving as the primary research site for ongoing Michigan moose population studies.
The details
Biologists monitor calf survival by fitting female moose with radio collars, which allow them to track the offspring born throughout the spring. While aerial surveys are conducted every two years to estimate total numbers, this granular tracking provides a clearer picture of how well calves survive in the Michigamme Highlands compared to other regions. Researchers plan to continue this intensive data collection through 2028 to better understand population stagnation.
Timeline
1930s: Initial moose reintroduction attempted in Michigan.
1980s: Moose Lift transports 59 moose from Ontario to Michigan.
2023: Aerial survey estimates 426 moose in the core survey area.
May and June 2026: 22 moose calves born and fitted for study.
September 2026: Tracking period concludes for the 14 surviving calves.
The Home Front
Michigan's current moose research follows the legacy of the 1980s Moose Lift, which remains the most significant intervention to build the state's herd. Today's studies refine those early population efforts by identifying the specific biological hurdles calves face in a stable, yet stagnant, habitat.
Residents living near the Michigamme Highlands or throughout the Upper Peninsula should remain aware of increased moose activity on rural roads, especially during seasonal migration periods. If you encounter a moose while driving or hiking, maintain a significant distance for your safety and the animal's wellbeing.
The takeaway
The 64 percent survival rate of moose calves in 2026 is a positive sign for Michigan's efforts to grow its current herd of roughly 300 animals. Those interested in local wildlife trends can keep the 2028 study conclusion date on their calendars for future population updates.
