MESSAGE FROM THE DIRECTOR Game transplants in Alaska have increased hunting opportunity, resulted in more food for Alaskans, affected Alaska’s environment, and created some interesting history. In 1973, Bud Burris and Don McKnight wrote the first edition of Game Transplants in Alaska, covering efforts that occurred from before statehood until that time. Much has happened since then, which is why I asked Tom Paul to update their report. It is important to document transplant efforts, to understand what makes them work well and how to avoid identified pitfalls in future efforts. Paul’s report provides a substantial look at both successful and unsuccessful efforts, and the benefits, challenges, and consequences of moving animals from one place to another. He accomplishes this while relating some good stories of biologists and community helpers exercising their ingenuity. While introductions of wildlife to previously uninhabited areas can benefit both the species and people, great care must be taken to avoid negative impacts to those introduced animals or existing indigenous species. This new edition details how the attitudes toward and techniques used to accomplish game transplants have changed through the years. Importantly, a new transplant policy, adopted by the Alaska Department of Fish and Game since the first edition of this report, set strict guidelines for wildlife transplants. I have personal experience with this topic. As an area wildlife biologist living and working in Ketchikan during the 1990s, I had the opportunity to oversee the introduction of mountain goats to Deer Mountain on Revillagigedo Island. Efforts were made beforehand to assess habitats and ecological implications. As with other introductions, time will tell whether our assessment was sufficiently thorough and accurate. In the meanwhile, that introduction, like others, has provided new hunting and viewing opportunities for Alaskans and visitors alike. While the Revillagigedo introduction met the department’s standards, a subsequent proposal to introduce mountain goats to Prince of Wales Island was rejected by the department after an ecological assessment determined there was insufficient wintering and escape habitat to support a viable population of goats on that island. We need to be ready to support wildlife transplants where they are appropriate and reject them where they are not. As you read this publication, I hope you will reflect both on the positive aspects and inherent risks associated with transplants. It remains my hope that introductions and reintroductions of wildlife in Alaska, undertaken with appropriate care, will provide positive benefits to the species, to Alaskans, and to all who visit our state. I hope too that the information presented in this new edition of Game Transplants of Alaska will help biologists and others steer a course to positive results from any future wildlife transplant operations. —Doug Larsen, Director, Division of Wildlife Conservation September 2009 TABLE OF CONTENTS PREFACE TO THE SECOND EDITION ����������������������������������������������������������������������������� viii ACKNOWLEDGMENTS ���������������������������������������������������������������������������������������������������������x EXECUTIVE SUMMARY ������������������������������������������������������������������������������������������������������ xi INTRODUCTION ���������������������������������������������������������������������������������������������������������������������1 ALASKA TRANSPLANT OBJECTIVES ��������������������������������������������������������������������������������5 BIG GAME TRANSPLANTS ���������������������������������������������������������������������������������������������������9 Sitka Black-tailed Deer ��������������������������������������������������������������������������������������������������������9 Mountain Goat �������������������������������������������������������������������������������������������������������������������16 Elk ��������������������������������������������������������������������������������������������������������������������������������������33 Bison ����������������������������������������������������������������������������������������������������������������������������������44 Muskox ������������������������������������������������������������������������������������������������������������������������������55 Moose ���������������������������������������������������������������������������������������������������������������������������������69
