This book assesses Alaskan wolf and bear management programs from scientific and economic perspectives. Relevant factors that should be taken into account when evaluating the utility of such programs are identified. The assessment includes a review of current scientific knowledge about the dynamics and management of large mammalian predator-prey relationships and human harvest of wildlife in northern ecosystems, and an evaluation of the extent to which existing research and management data allow prediction of the outcome of wolf management or control programs and grizzly bear management programs. Included is an evaluation of available economic studies and methodologies for estimating the costs and benefits of predator control programs in Alaska.

- 8 Conclusions and Recommendations
- INTRODUCTION
- BIOLOGICAL CONCLUSIONS AND RECOMMENDATIONS
- Conclusion 1: Wolves and bears in combination can limit prey populations
- Conclusion 2: Wolf control has resulted in prey increases only when wolves were greatly reduced over ...
- Conclusion 3: Expectations that managed populations in Alaska will remain stable are not justified
- Conclusion 4: Data on habitat quality are inadequate
- Conclusion 5: Modeling of population dynamics will enhance the use of data already collected and ena ...
- Conclusion 6: Wolves, bears, and their prey are vulnerable to human actions but in different ways
- Conclusion 7: The design of most past experiments and the data collected do not allow firm conclusio ...
- Conclusion 8: Perfect prediction is unattainable.
- Conclusion 9: Many past predator control and management activities have been insufficiently monitored
- SOCIOECONOMIC CONCLUSIONS AND RECOMMENDATIONS
- Conclusion 10: Benefit-cost analyses of management changes require at least three categories of info ...
- Conclusion 11: Evaluations of Alaska predator control programs have not gathered, analyzed, and asse ...
- Conclusion 12: Social science research in Alaska is needed to support the design and evaluation of predator control ...
- Conclusion 13: Wildlife is, by definition, a public resource
- Conclusion 14: Greater potential for agreement may exist among Alaska's diverse constituency than is generally
assumed
- Conclusion 15: Conflicts over management and control of predators are likely to continue indefinitely
- Conclusion 16: Decentralization of decision-making authority is not a panacea for solving wildlife m ...
- Conclusion 17: Interagency cooperation could improve management, reduce public confusion, and elimin ...
