Determining factors affecting trends in restored wolf populations The gray wolf (Canis lupus) in Minnesota, Wisconsin, and Michigan has been on and off the Endangered Species List since March 2007, and in late 2014 was placed back on because of legal technicalities, although biologically it is recovered there with > 4,000 wolves. The wolf has been restored to Yellowstone National Park and Montana and Idaho, is repopulating Oregon and Washington, and is being restored to Arizona and New Mexico. The federal government must continue monitoring wolf populations for 5 years post-delisting. By studying the long-term trend of an extant wolf population and its prey, scientists and managers can gain insights into the population and demographic trends that can be expected in restored populations.... Categories: Project Biology of wolves and Canada lynxes and their prey in pristine and restored ecosystems Wolves (Canis lupus) and Canada Lynxes (Lynx canadensis) are on the Endangered Species List. Both inhabit pristine habitat in Minnesota, where it is possible and important to study their biology and interaction with their prey under natural conditions. These studies will allow managers and administrators to assess the progress of restoration and recovery of these species and anticipate biological and political problems that may arise during recovery. Most contentious is the issue of wolf interaction with their prey. Thus studies of wolf prey animals such as deer (Odocoileus virginianus), moose (Alces alces) and elk (Cervus elaphus) and the interactions of wolves with them are as important as investigatio [see Narratives...
