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.
