Acknowledgments

The Lichen Management Recommendations were prepared with the input and review of many individuals, whom we gratefully acknowledge. Chiska Derr, Linda Geiser, and Robin Lesher had lead responsibility for individual documents.

We thank all students of lichens, both historical and present, who have contributed to our knowledge of their distribution, habitats, and ecology and generously shared this information through their herbarium collections, publications, and personal communications. The following herbaria kindly provided specimens and assistance: California Academy of Science (CAS), Duke University (DUKE), Humboldt State University (HSC), Marion Ownbey Herbarium, Washington State University, Pullman (WS), Oregon State University (OSC), including the private herbarium of Bruce McCune, San Francisco State University (SFSU), U.S. Herbarium, Smithsonian Institution (US), University of British Columbia (UBC), University of California, Berkeley (UCB), University of Washington (WTU), Western Washington University (WWB), the Siuslaw National Forest Herbarium. John Davis shared specimen information from his private herbarium.

Many lichenologists and other scientists provided specific technical advice and input during the preparation of the Management Recommendations. They include Suraj Ahuja, Shelly Benson, Mark Boyll, Irwin Brodo, Doug Glavich, Katie Glew, Trevor Goward, Jan Henderson, Marusa Herrera-Campos, Bruce McCune, Fred Rhoades, Jim Riley, Roger Rosentreter, Abbey Rosso, Sylvia and Steve Sharnoff, Steve Sillett, Larry St. Clair, Tor Tønsberg, and Barbara Williams. In addition, Katie Glew, Fred Rhoades, Bruce Ryan, Angel Dawson, Cheryl McCaffrey, and John Davis reviewed earlier drafts. Mark Boyll assisted in the preparation of early versions of these documents.

A technical review team was comprised of individuals selected to represent the perspectives of management and field implementers. An expert on the intent of Record of Decision and the Lichen Taxa Lead also participated in this process. The team included Lisa Hoover, Brad Keller, John Bacho, Robin Lesher, and Nancy Fredricks. Sheila Martinson and Norm Gartley served as review coordinators. Martha Brooks assisted with technical editing. Robin Lesher and Nancy Fredricks completed the final editing.
