Moose Research Objectives
Using a co-stewardship framework led by State and Tribal project partners, this study focuses on one of the most critical — and least understood — phases of moose recovery in Minnesota: the years when young moose first survive into adulthood and begin reproducing.
Specifically, we are investigating the recruitment of young moose (approximately 1 to 3 years old) into the breeding population by measuring survival, causes of mortality, habitat use, and the age at which females first become pregnant and successfully raise calves. These early adult years often determine whether a population rebounds or continues to decline.
By filling this key knowledge gap, the research is designed to translate field data into practical wildlife and habitat management strategies that can support moose recovery across northeastern Minnesota and the 1854 Ceded Territory.
So much important moose research has occurred in our state to help us improve our understanding of the population decline. Here, we are filling a critical gap in knowledge, and the partnership really sets the project apart — particularly the commitment to engaging and inspiring the public in moose protection.
Objectives At A Glance
To understand how moose populations recover, we need to understand what happens between calfhood and full adulthood — a life stage that has historically received far less study than calves or fully mature adults.
For yearlings and young adult moose, survival, habitat quality, and early reproduction are tightly linked. These years represent the point at which moose either successfully replace themselves in the population or quietly fall out of it.
This study focuses on measuring those relationships so the results can be translated into real-world management actions.
Two core concepts guide the work:
Recruitment asks: How many young moose survive long enough to join the breeding population?
Fecundity asks: How many calves young females produce — and how many of those calves survive?
Together, recruitment and fecundity help explain whether the population can sustain itself over time, and where targeted habitat and wildlife management can have the greatest impact.
Three Key Research Objectives
These objectives focus on the age classes that determine whether moose successfully recruit into the breeding population and begin contributing calves to future generations.
GPS Collars For Survival, Mortality, And Habitat Use
We will deploy satellite GPS collars on young moose during their first winter (approximately 8–9 months old) across northeastern Minnesota’s core moose range. Over a five-year period, these collars will allow researchers to:
- Measure survival rates through early adulthood
- Investigate cause-specific mortality when mortality signals occur
- Understand how young moose use habitat across seasons and landscapes
This information is foundational for identifying where and why young moose are most vulnerable.
Non-Invasive Sampling For Age Of First Pregnancy
Using non-invasive fecal pellet collection, researchers will determine whether collared female moose become pregnant as yearlings or young adults. Identifying age of first pregnancy helps reveal whether nutrition, habitat conditions, or environmental stressors may be limiting reproduction at a population level.
Birth Rates And Calf Survival For Young Females
GPS collar data combined with aerial thermal surveys will be used to measure:
- Parturition rates (the percentage of females that give birth)
- Fecundity (number of calves born)
- Calf survival for 2- and 3-year-old females
These are the first reproductive attempts for many cows — and success or failure at this stage can shape population trends for years to come.
Why This Study Is Needed
Moose are a keystone species of Minnesota’s boreal forests and hold deep cultural, ecological, and subsistence importance across northeastern Minnesota and the 1854 Ceded Territory.
Yet over the past two decades, the moose population has declined dramatically, driven by climate stress, disease, parasitism, habitat change, and complex predator dynamics.
Minnesota has a long history of strong moose research, particularly on adult survival and newborn calves. What has been missing is a clear picture of what happens in between — when calves become yearlings, when young females first attempt to reproduce, and when survival pressures may quietly limit recovery.
This study is designed to close that gap.
Results will help identify:
- When and where female moose begin calving, and how that timing varies across the landscape
- Which habitats support survival and reproduction for yearlings, young adults, and their calves
- Primary causes of mortality during early adulthood
- How interacting species — including deer, wolves, and black bears — influence recruitment and calf survival
- Where forest management could have the greatest positive impact if pregnancy or calf survival varies by location
Co-Stewardship and Research Collaboration
This research is built through a co-stewardship framework that brings together State and Tribal leadership, long-standing scientific expertise, and shared responsibility for Minnesota’s moose.
The study also builds directly on the Grand Portage Band of Lake Superior Chippewa’s ongoing moose research. Their work has helped demonstrate safe and effective methods for collaring juvenile moose and has provided critical real-time collar data used to test and refine field methods — including fecal sampling and aerial thermal survey techniques.
Together, this collaboration strengthens both the science and its application, ensuring the work reflects Indigenous stewardship, rigorous wildlife health research, and long-term conservation goals.
