EnviroThursday - "Moose Mortality in Northern Minnesota: A Report from the Grand Portage Band of Lake Superior Chippewa"

12:00 PM  - 1:00 PM
Thursday Mar 23, 2017
Olin-Rice Science Center 250

Speaker:  Seth Moore, Director of Biology and Environment, Grand Portage Band of Lake Superior Chippewa

The Minnesota moose population (Alces alces), like many along the southern extent of the North American moose range, has been experiencing a precipitous decline in recent years. Moose are one of the primary subsistence species for the Grand Portage Band of Lake Superior Chippewa and the tribe is deeply concerned over their decline in recent years. The Grand Portage tribal government has invested heavily in moose research and restoration and strives to see the eventual restoration of a sustainable population in Minnesota. Ongoing population surveys of moose on Grand Portage Indian Reservation (GPIR), MN reveal high levels of adult mortality and low annual calf recruitment which is likely related to effects of a warming climate. The Grand Portage Band began a moose collaring program in 2009 and has developed it into a successful program evaluating habitat use, cause-specific mortality, and maternal and calf health relationships. To better understand causes of mortality in the population of moose on GPIR, their team has collared 141 moose since 2010, including 105 adults and 36 calves. This talk will cover the findings of this collaring program, as well as suggestions for management strategies to support a declining moose population.

Seth Moore, PhD., has worked for the Grand Portage Band of Lake Superior Chippewa since 2005 and he presently manages the Grand Portage Department of Biology and Environment.  Dr. Moore has worked on Lake Superior fisheries and regional environmental issues for over 23 years. He earned his PhD in Water Resources Science from the University of Minnesota (2008), a master’s degree in Environmental Biology also from University of Minnesota (1998), and a bachelor’s dual degree in Biology and Environmental Studies from Northland College in Ashland, WI (1994).  Dr. Moore focuses his research efforts on subsistence species of the Grand Portage Band of Chippewa. His current projects include coaster brook trout restoration and identifying habitats used by moose under a warming climate.
