Plot centers were established and GNSS locations were taken by USFS Southern Research Station
personnel in burn units G20, G25 and L25 for the 2023 Eglin Air Force Base study fires. A 16-m
line transect intersected the plot center. Duff and litter samples were taken at 0, 5, 11, and
16 m along the transect pre-fire. After the fire, samples were taken at 1, 6, 10, and 15 m along
the transect. Duff was measured by inserting a soil sampler ~0.1 m into the soil, then
extracting the core and searching for the transition from organic (if present) to mineral soil.
Multiple diagnostic criteria for duff (organic horizon) were defined through consultation with
an expert (Dr. Mac Callaham from USFS-SRS). We applied these criteria to define the boundary
between duff and mineral soil. These criteria included dark color; absence or paucity of sand
grains; and cohesion (e.g., due to fungal hyphae). Nuria Sanchez-Lopez and Seth Bigelow
frequently cross-checked duff-mineral soil boundary delineations and trained field personnel
until they could identify the boundary consistently. Transitions were often unclear and sometime
included alternating layers of sand and duff. Litter depth was measured for soil surface to
highest litter particle in contact with the ground at the point of measurement. Fuels were
measured by tallying 100-hr fuels that intersected the 16-m transect. 1000-hour fuels were
measured for diameter at the point where they intersected the transect. A total of 208 plots
were established, with 75, 93, and 40 plots occurring in units G20, G25, and L25, respectively.
After the study fires in March 2023, trees within 10 m of plot center were identified to
functional group (pine, hardwood or species), measured for diameter at breast height with a
diameter tape, measured for distance from outer bark to plot center, and measured for azimuth
from plot center to tree. Some post-processing was done using lidar scans to distinguish between
evergreeen and deciduous hardwoods. Saplings were tallied by ordinal quadrant (up to 5 m from
plot center). Tree measurements were not taken in unit L25. In unit G20, plots HH01, HH02, HH03,
HH04, HH05 were sampled pre-fire but not post fire. In unit G25, plots HH105, HH95, PP16 were
sampled pre-fire but not post fire.
The field protocol included in the data package
(Eglin_2022_Tree_and_Transect_Field_Protocol.pdf) contains more methodological details.
