Volunteer Profile: Rick and Jean Seavey

Rick and Jean Seavey have been research collaborators with Everglades National Park for more than 25 years. Honors include the Marjorie Stoneman Douglas Award from the Dade Chapter of the Florida Native Plant Society in 1989 for first use of large community volunteer groups in non-native plant removal (Royal Palm Hammock), the George B. Hartzog Award from the National Park Service (2009) Enduring Service Category, and the naming of a lichen (Heiomasia seaveyorum Nelson & Lücking) in their honor in 2010.

Everglades National Park Lichen Project

Rick and Jean lead the Everglades National Park lichen project, which is being conducted completely by volunteers. Major contributions have been made by seasonal, local, and student volunteers. Support has been provided by the National Park Service volunteer program, Everglades National Park Inventory and Monitoring Program and Science Communication Team, and the South Florida National Parks Trust.

Rick Seavey is the only known systemic taxonomic lichenologist in south Florida and possibly all of Florida. As of 2010, the Everglades National Park lichen project has identified 550 species of which at least 50 are additions to the North American Lichen Checklist. Thirteen species have been described and published as new to science and an additional 7 species are in press. More than 3,000 specimens have been delivered to the National Park Service South Florida Collections Management Center for archiving, and several hundred more specimens are currently being processed.

The Seaveys are always looking for help! Call the Everglades National Park Volunteer Coordinator at 305-242-7752 to learn how you can volunteer to help Rick and Jean with their lichen project or with any of the many other opportunities available in the park.
