Restoration Through Partnerships

HomeWhat We DoRestoration Through PartnershipsLEO

Southeast Longleaf Ecosystem Occurrences (LEO) Geodatabase

The LEO Goal

To develop a comprehensive, shareable map database of longleaf ecosystem occurrence across the range, with standard attributes that enables states and partners to view and analyze spatial data for longleaf pine occurrence and condition at multiple scales.

The LEO Process

Compile existing longleaf pine data. We gathered longleaf pine information from dozens of land management agencies, private partners, and public data sources. LEO aims to “fill in the gaps” of where we know longleaf to occur, so this step is crucial to allow us to avoid areas where reliable data is already available.

Kisatchee NF

Develop areas for field assessment. The mapping team at Florida Natural Areas Inventory and The Longleaf Alliance identify and delineate areas on the landscape where longleaf likely occurs, based on aerial photo signatures along with informing datasets such as a longleaf probability model, species habitat models and occurrence locations, and burn permits.

Polygon imagery

Collect Rapid Assessment field data. The rapid assessment provides ground truth data for the LEO mapping effort. Sites are surveyed for the occurrence of longleaf and assessed for ecological condition using a standardized, thorough, and repeatable format by which a field surveyor describes what he/she observes. Surveys are designed to be rapid and completed largely by roadside observations. Field work occurs with the help of partner agencies and contractors.

KZB field collector

Quality checks and incorporation into the geodatabase. Field survey data undergo quality assurance checks at different stages including checks by field surveyors prior to syncing their data and by the LEO data management team prior to integration into the database. Integration involves cross-walking management condition assignments identified by ALRI of Maintain, Improve, or Restore.

Asset 2

LEO is implemented by Florida Natural Areas Inventory and The Longleaf Alliance. Funding is provided by the Natural Resources Conservation Service via the U.S. Endowment for Sustainable Forestry and Communities. We would like to thank all LIT partners and coordinators for their support.

Here's something to toast to 🍻 The Longleaf All Here's something to toast to 🍻 The Longleaf Alliance is Appalachian Mountain Brewery's Brewing Good partner for the month of April!Not only will our Pints for Pines partnership with AMB and their Long Leaf IPA mean longleaf pine trees in the ground, but a dollar for every pint sold on April 3rd's Pint Night will provide a direct contribution to TLA.P.S. Check out our recent collaboration with AMB and Three River Land Trust to plant 2,000 longleaf seedlings in North Carolina (link in bio).
Did you know that March 25th is National Peacock D Did you know that March 25th is National Peacock Day? No? Well now you do 😊📷 Karen Brown, Bladen County, North Carolina#longleaf #longleafpine #longleafpines #longleafpineecosystem #restorelongleaf
We loved celebrating with new and old friends at t We loved celebrating with new and old friends at the Pints for Pines Longleaf Planting day! Especially this father-son planting duo 😍The “Pints for Pines" program unites beer and nature enthusiasts to restore the longleaf pine ecosystem. Every case of @appalachianmountainbrewery Long Leaf IPA sold supports the planting of longleaf pine trees.Special thanks to @threeriverslandtrust for being gracious hosts at Cotton Creek Preserve in Mongtomery County, North Carolina. #restorelongleaf #fortheloveoflongleaf #pintsforpines
