ACKNOWLEDGMENTS

This project was a cooperative effort among the Michigan Department of Natural Resources, The Minnesota Department of Natural Resources, the U. S. Fish and Wildlife Service, Northern Michigan University, the Huron Mountain Wildlife Foundation, and the National Audubon Society.

The Michigan and Minnesota Departments of Natural Resources provided the legal permits and logistical support necessary for the transplant. The Fish and Wildlife Service assisted in the planning and fund-raising for the overall project, and provided the technical expertise in the live-trapping, radio-tagging and radio-tracking of the wolves. Northern Michigan University initiated and administered the project and conducted the Michigan aspects of the work. Financial support was provided by the Huron Mountain Wildlife Foundation and the National Audubon Society.

Dr. U. S. Seal of the Veterans Administration Hospital in Minneapolis analyzed and interpreted the blood samples, and Dr. Ray D. Barnes, University of Minnesota, the female reproductive tracts.
