During the preparation of this document, the cranes lost three of their most dedicated students and ardent admirers. Thomas T. Tacha devoted a substantial portion of his career as a wildlife biologist to advancing our understanding of North America’s Sandhill Cranes, and contributed importantly to the Sandhill Crane account that appears in this volume. Gretchen Holstein Schoff was an early and constant supporter of the International Crane Foundation, and a devoted friend and advisor to the compilers of this action plan. Through the publication Reflections: The Story of Cranes, she continues to touch crane enthusiasts around the world. More than any other single individual, Lawrence Walkinshaw built the foundation upon which this action plan rests. His lifelong commitment as a scientist, writer, and conservationist continues to inform and inspire all those who work to ensure a secure future for the cranes. This action plan is dedicated to the memory of these three special individuals.
