Scientists working to preserve
Minnesota moose herd
Scientists have restored 1,000 acres of moose foraging habitat near Lake Superior and are working on other wildlife management activities in an effort to sustain the moose herd in eastern Minnesota.
Moose are one of the most cherished and threatened wildlife species in Minnesota. The moose population in northwestern Minnesota decreased over the past 20 years, from more than 4,000 animals to fewer than 100. Scientists fear climate change could cause a similar decline in the moose herd in northeastern Minnesota, on the uplands along Lake Superior. Researchers have counted more than 7,000 moose in northeastern Minnesota in recent years, but scientists have recently observed higher mortality among moose that have been fitted with radio collars. The increased mortality has been tied to climate change. Scientists at the University of Minnesota-Duluth are leading an effort to sustain the moose population in northeastern Minnesota by restoring foraging habitat that the animals need to survive. Researchers are also developing habitat guidelines that will help private property owners and public land managers provide the best possible habitat for the animals. A grant from the Great Lakes Restoration Initiative allowed researchers to restore 200 acres of moose foraging habitat near wetlands and evaluate whether moose are using another 800 acres of previously restored foraging habitat. Initial results indicated that moose are using the restored foraging habitat. The GLRI project is part of a larger, decade-long effort to better manage moose habitat. The hope is that improved habitat management activities will prevent a major decrease in the moose population in northeastern Minnesota.
Resource Challenges Addressed
- Loss of moose foraging habitat
- Climate change
MOOSE FORAGING HABITAT RESTORATION

Results and Accomplishments
Moose are actively using 1,000 acres of restored foraging areas, which could help the animals survive climate change.
