Moose Decline and Air Temperatures in Northeastern Minnesota
Moose, one of Minnesota's prized wildlife species, are dying at much higher rates in Minnesota than elsewhere in North America. Recently observed increases in mortality rates amongst some moose in northeastern Minnesota have led to concern that the population there may be entering a decline like that seen in the northwestern part of the state, where moose populations fell from over 4,000 to fewer than 100 in less than 20 years. Additionally the specific causes of increased mortality amongst individual moose remain under investigation. Scientists at the Minnesota Department of Natural Resources are using this appropriation to help understand how air temperature affects moose habitat use and behavior, reproductive success, and survival in order to determine if, when, and how moose are able to successfully modulate internal body temperature. Knowledge gained will be used by federal, state, and local natural resource agencies to identify appropriate management and habitat needs and actions that can be taken to help slow or prevent continued population declines in northeastern Minnesota of this iconic, keystone species.
$600,000 the second year is from the trust fund to the commissioner of natural resources in cooperation with the University of Minnesota to study the physiology and behavior of adult moose and effects of female condition on calf production and survival to determine the impact of air temperature on moose population performance and decline. This appropriation is available until June 30, 2017, by which time the project must be completed and final products delivered.
