12 Moose Management in Minnesota Moose is an important part of a subsistence diet and the culture of Tribes in northeastern Minnesota. One animal can provide 400-700 pounds of meat. Moose numbers have declined nearly 50% since 2006. Tribes and the 1854 Treaty Authority collaborate with federal, state, and academic institutions on moose research and population studies. The goal is to determine causes and potential remedies for a declining population. Particular focus is on improving moose habitat by identifying the best forage for these large herbivores. The 1854 Treaty Authority and its Tribes undertake aerial surveys to locate and track moose in northeastern Minnesota. These and other surveys generate information on animal health, movement, and population size. Necropsies are performed to determine mortality causes. These data feed into overall inter-agency coordination on moose management.
