We gratefully acknowledge the cooperation and participation of the U.S.D.A. Forest Service and its personnel in the National Forests in Florida for assistance in planning, logistics and access to areas investigated in the course of this work. Guy Anglin (USFS) and Lorraine Miller (USFS) were especially helpful in planning and conducting the fieldwork. The project could not have been completed without the help of Florida Natural Areas Inventory ecologists Ann Johnson, Brenda Herring, Gary Schultz, and Carolyn Kindell.
