The Florida Longleaf Pine Ecosystem Geodatabase

The Florida Forest Service and the Florida Natural Areas Inventory have partnered to develop the Longleaf Pine Ecosystem Geodatabase (LPEGDB). This spatial database will serve as the central repository for data on the distribution and ecological condition of longleaf pine ecosystems in Florida. The database includes data provided by many partner agencies and organizations as well as new field assessment data collected for this project.

The Longleaf Pine Ecosystem Geodatabase represents a major step toward fulfilling both inventory and assessment objectives of Florida’s Forest Action Plan [ Adobe PDF Document ] and America’s Longleaf 2009 Range-wide Conservation Plan for Longleaf [ Adobe PDF Document ]. Ultimately, it will provide guidance on where and how to accomplish goals for conservation, restoration and management of longleaf pine ecosystems. As funding allows, the Florida Forest Service and Florida Natural Areas Inventory will continue to enhance, improve, and update the database, along with related tools and maps.

Why Longleaf Pine Matters

Longleaf pine ecosystems are among the most diverse in North America, supporting a large array of herbs and grasses, as well as rare animal species such as red-cockaded woodpeckers and gopher tortoises. Longleaf pine forests and savannas historically dominated the southeastern coastal plain. However, they were drastically reduced from an estimated 90 million acres to less than 3 million acres, largely due to urbanization, overutilization, conversion to other land uses, and exclusion of natural fire regimes.

Much of the remaining acreage exists as fragmented stands in varying degrees of isolation. Recently, however, many organizations and agencies have taken steps to prevent further loss, improve what’s left, and restore the longleaf pine ecosystem where practicable. The Longleaf Pine Ecosystem Geodatabase  contributes to this effort by providing detailed, baseline data on the location and current ecological condition of remaining longleaf sites in Florida.

Current Project Results

  • There are 2.15 million acres of longleaf pine ecosystems confirmed in Florida, more than half of all known longleaf.
  • Thirty-eight percent (817,000 acres) of this is on private lands.
  • Data on ecological condition is available for 78 percent (1.69 million acres) of Florida’s longleaf pine ecosystems.
  • An additional 192,000 acres of longleaf natural communities have been identified from aerial photos, which were supplemental to on-the-ground data collection.

Versions

LPEGDB v.1, published June 2014. This version corresponds to the LPEGDB Final Report and represents all tasks involved in the initial development of the database, including compilation of potential longleaf pine ecosystems, extensive mining of existing assessment data, and the rapid assessment of more than 800,000 acres of longleaf pine ecosystems by the Florida Forest Service.

LPEGDB v.2, published October 2014. Version 2 fills several remaining data gaps on managed conservation lands, especially gaps in ecological condition of longleaf pine ecosystems. Updates are included for lands managed by the Florida Forest Service, Eglin Air Force Base, U.S. Forest Service, and St. Johns River Water Management District, as well as longleaf plantings on private lands.

LPEGDB, v.3, published September 2015. Version 3 includes updates based on FNAI field projects and several partner data sources. Attributes and summaries for conservation lands and land cover were added and the database format was revised. The Rapid Assessment Data Collection Model was also updated and field data collection tools are available upon request.
