Tree data collected in 2017 in the 2012 RxCADRE forested burn unit at Eglin Air Force Base

This publication contains a comma-separated values (CSV) file containing tree attribute and stem geolocation data collected in April 2017 in the L2F forested management unit at Eglin Air Force Base in Okaloosa County, Florida. The L2F unit was the last unit, and the only forested unit, burned as part of the 2012 Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) funded by the Joint Fire Science Program. The RxCADRE prescribed burn was on 11 November 2012, after 2.5 years (3 growing seasons) since the previous prescribed burn on 3 April 2010. This data file contains field-measured attributes of the trees found within 3 large circular plots of 25-meter radius that correspond to the 3 Highly Instrumented Plots (HIPS) placed in the L2F unit for the 2012 RxCADRE burn. There were 353 trees measured 1-3 April 2017, distributed between the 3 HIPS. Before the 2017 tree data collection but after the 2012 RxCADRE burn, a wildfire occurred on 8 April 2016 that was contained on 9 April 2016.
The 2012 RxCADRE, and subsequent 2019 and 2020 Strategic Environmental Research and Development (SERDP) projects, were developed to respond to the need for integrated, quality-assured fuels, atmospheric, fire behavior, energy, smoke and effects measurement datasets for calibrating and validating fire and smoke models and tackle fundamental fire science questions. A goal of these projects is to provide quality-assured datasets in a public database to promote data sharing and usage between scientists, managers and anyone who wants them. These tree data could be used for several fuel or fire applications, such as estimating canopy- or crown-level fuels or for running fire behavior simulations, particularly with computational fluid dynamic modeling of fire behavior that uses the spatial distribution of trees to account for the drag on airflow.

(2023), which used a subset of these trees (n=205) that were not multi-stem, not dead, and not < 10 centimeters at diameter at breast height (DBH).
