Reference Natural Communities

There remain today virtually no pristine examples of the biological communities that constitute Florida's natural landscape. There are still some places, however, where the ecological condition of existing natural communities is of sufficiently high-quality that these select examples can serve as models for that community type. As models, each reference natural community exhibits the species diversity, species composition, physical structure, and general ecological integrity expected for that FNAI natural community type. Reference natural communities provide a standard against which to measure the condition of similar communities—a starting point for establishing desired future conditions to inform land management and restoration. These data augment the Guide to the Natural Communities of Florida, 2010 edition.

Data for these maps may be found on the GIS data webpage.

FWC Reference Sites

FNAI has identified 72 reference sites for 13 natural community types for which we developed detailed descriptions and quantitative characterizations that are presented here in an interactive map. Emphasis in this first phase, which was funded by the Florida Fish and Wildlife Conservation Commission, was given to actively managed natural community types to support FWC's adaptive land management decision support tool—Objective-based Vegetation Management. Multiple reference sites were identified for each natural community type across the community's geographic range to account for expected regional variation. Similarly, multiple reference sites were specifically identified to account for natural variation in species composition (e.g., oak scrub and rosemary bald). All reference natural community sites are publically accessible.

DEP Reference Sites

From 2018 to 2023, FNAI established and characterized 111 reference sites to provide an educational resource to DEP Environmental Resource Permitting (ERP) program regulatory staff conducting Uniform Mitigation and Assessment Method (UMAM, Chapter 62-345, F.A.C.) evaluations. These sites will serve as models for structure and composition, as well as ecological function, to improve standardization and objectivity of UMAM evaluations. Site characterization was developed through the use of level 5 Carolina Vegetation Survey plots. These resources will aid regulatory staff conducting impact assessments, mitigation bank permitters determining credit allocation, mitigation bank and other land managers preparing restoration or enhancement plans, and likely other parties, such as researchers and educators.
