Susan G. Clark knows her subject well. A professor of Wildlife Ecology and Policy Sciences, she has written many books on this topic. Clark draws extensively from her Yellowstone work—16 years of conjoining wildlife refuge leaders and national forest experts. She makes a passionate plea for wildlife survival, while focusing on today’s leadership and the future of the national park and its resources. By her own admission, she recognizes such weaknesses as lack of leadership, yet she offers pointed ways to resolve land issues and move forward to maintain Yellowstone’s pristine landscape in an ever-changing environment.
