PREFACE

This report was created through a continuing agreement between NatureServe, The Nature Conservancy (TNC) and U.S.D.A. Forest Service Region 8. This agreement provides for the application of the United States National Vegetation Classification (USNVC) standard to Region 8 Forests and will result in a basic list of vegetation units (alliances and community associations) presented on a Forest by Forest basis. The USNVC provides a framework for vegetation classification and is intended to serve as a tool for conservation planning and biodiversity protection, as well as resource planning, management, and vegetation mapping. In the southeastern United States, the USNVC is being developed in cooperation with the state Natural Heritage Programs, the U.S.D.A. Forest Service, and other state and Federal partners. Its development has involved consultation with many individuals and agencies and incorporates information from a variety of publications and other classifications.


This classification subset includes all alliances and associations attributed to the three National Forests in Florida (Apalachicola, Ocala, and Osceola), as well as some that are thought to occur on those forests but which are not confirmed. It is intended for review by Forest Service personnel and other ecologists in this geographic area. The fieldwork on the National Forests in Florida took place in 2001. Field reconnaissance is conducted in coordination with U.S. Forest Service personnel with the objective of visiting representative examples of all the major vegetation types, rare or unusual communities, and vegetation resulting from common forest management regimes.
The vegetation classification produced through this agreement will form the foundation for continuing use of the USNVC on U.S. Forest Service lands in Region 8 for natural resource planning and management. Because this is an interim report, the classification is incomplete and will rely on feedback and additional fieldwork to improve its coverage of the individual Forest unit. Over the coming year refinements, revisions, and additions will be made to this classification based on review by Forest Service personnel, review of other vegetation studies, and analysis of data collected during field reconnaissance. In the meanwhile, the entire National Vegetation Classification is available on-line in a fully searchable database that is updated on a quarterly basis (www.NatureServe.org).
Comments and suggestions for additions or revisions are welcome and encouraged. Please submit comments to the authors at the following address: NatureServe; Southern U. S. Office, 6114 Fayetteville Road, Suite 109, Durham, NC 27713-6284 or by phone or electronic mail: Carl W. Nordman: 919-484-7857 x153 (carl_nordman@natureserve.org) or Milo Pyne: 919-484-7857 x 136 (milo_pyne@natureserve.org).

ACKNOWLEDGMENTS

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.
