Growth Rate and Equilibrium Size of a Recolonizing Wolf Population in the Southern Lake Superior Region

  • Timothy R Van Deelen

9.1 Introduction

The northern forests of Wisconsin and Michigan’s Upper Peninsula provide an extensive area of habitat favorable for gray wolves (Canis lupus) and are relatively isolated from established wolf populations in Ontario and Minnesota. Boundaries include Lakes Superior, Michigan, and Huron. The recent population of wolves in Wisconsin and Michigan evidently was founded by dispersing wolves that arrived in the mid-1970s. Growth of this population occurred while populations of white-tailed deer (Odocoileus virginianus) were at or near historic highs in abundance. Consequently, the re-colonizing wolves were entering a very high quality habitat where other major predators on adult deer such as grizzly bears (Ursus arctos) or cougars (Puma concolor) were absent. In addition to being an interesting ecological case study of density dependence and population growth in a population of large terrestrial predators, growth of this population has important conservation significance....
