Study site Eglin Air Force Base (EAFB) is a 464,000 acres United States Air Force (USAF) base in the western Florida Panhandle, located in Santa Rosa, Okaloosa, and Walton counties. Approximately 300,000 acres are managed with prescribed fire for the longleaf pine ecosystem. EAFB typically prescribe burns roughly 90,000 acres per year. The fire return interval is about 3 years, but with the right conditions, EAFB Wildland Support Module will burn a unit every 18 to 24 months. In 2023, G-20 (382 ha/946 ac), G-25 (548 ha/1354 ac), and L-25 (117 ha/290 ac) were available for prescribed burning. These burn units are primarily longleaf pine (Pinus palustris) - turkey oak (Quercus laevis) sandhills where maximum tree height is 60-70 feet. Sand pine (Pinus clausa) is also present, and despite its designation as a native species, it is considered invasive at this site. EAFB reduces sand pine populations by manually cutting trees and burning seedlings; the downed sand pines from population control are left until burning, greatly contributing to large woody debris in the fuel bed (100 – 1000-hour fuels). G-20 and G-25 are located on the western side of EAFB. G-20 is between Range Road 213 and B-70, and G-25 is south of B-70 and split by Live Oak Creek. These units were burned three years ago (2020). L-25 is located on the eastern side of EAFB, south of Range Road 213, across from the C80C Test site. It was last burned 4 years ago (2019). The ground cover is dominated by wiregrass (Aristida stricta). This unit also has small oak hammocks, dominated by live oak (Quercus virginiana) and sand live oak (Quercus geminata). G-20 and G-25 were broken into smaller, more manageable sampling blocks. Using a remnant, undesignated EAFB road, G-20 was split into G-20W (184 ha/455 ac) and G-20E (193 ha/476 ac). Live Oak Creek was used to split G-25 into G-25W (235 ha/581 ac) and G-25E (311 ha/770 ac). The EAFB Wildland Support Module conducted the prescribed burns. Ignition was hand and ATV/UTV. G-25W was burned on March 11, 2023. Due to rain, only a small portion of G-25E was burned on March 12, 2023. On March 16, 2023, the rest of G-25E was burned. G-20W and G-20E were burned on March 19, 2023. NOTE: A prescribed burn was not conducted at L-25 during this campaign. Therefore, this unit does not have post-burn data. |
