The Biodiversity Matrix Map Server is a screening tool from FNAI that provides immediate, free access to rare species occurrence information statewide. This tool allows you to zoom to your site of interest and create a report listing documented, likely, and potential occurrences of rare species and natural communities.
The FNAI Biodiversity Matrix offers built-in interpretation of the likelihood of species occurrence for each 1-square-mile Matrix Unit across the state. The report includes a site map and list of species and natural communities by occurrence status: Documented, Documented-Historic, Likely, and Potential.
The Biodiversity Matrix includes all species and natural communities tracked by the Florida Natural Areas Inventory, including all federal listed species. Species that are common and wide-ranging in Florida are not included.See tracking list here.
FNAI Element Occurrence data are built into the Biodiversity Matrix. Element occurrences with high locational precision are generally listed as Documented in the Matrix, while lower-precision occurrences may be listed as Likely or Potential.
The Biodiversity Matrix includes more information than just element occurrences however. Occurrence-based potential habitat models, natural community models, and species predicted range models are also included to fill in the gaps between documented occurrences.
Some government agencies or other organizations require a statement of on-site natural resources from FNAI as part of an application or regulatory process. Although we are not the authority on such requirements, FNAI generally does not consider the Biodiversity Matrix report generated from our website map server as an official statement from FNAI. Instead we offer a Standard Data Report which generally meets those requirements.
For many element occurrences, we do not have location information precise enough to map the occurrence to less than a square mile. Smaller Matrix Units would therefore result in very few species ever being listed as Documented in a Unit. Also, some FNAI occurrences are considered "data sensitive", and our policy is not to give out more precise information for those occurrences.
As always, more precise information is available - request a Standard Data Report.
The occurrence status of species and communities in the Biodiversity Matrix is defined as follows:
The data maintained by the Florida Natural Areas Inventory represent the single most comprehensive source of information available on the locations of rare species and other significant ecological resources statewide. However, the data are not always based on comprehensive or site-specific field surveys. Therefore, this information should not be regarded as a final statement on the biological resources of the site being considered, nor should it be substituted for on-site surveys. FNAI shall not be held liable for the accuracy and completeness of these data, or opinions or conclusions drawn from these data. FNAI is not inviting reliance on these data. Inventory data are designed for the purposes of conservation planning and scientific research and are not intended for use as the primary criteria for regulatory decisions.
