Data from: Assessing Umbellularia californica basal resprouting response post-wildfire using field measurements and ground-based LiDAR scanning

This archive provides code and data for reproducing the results of Bell et al. 2025, "Assessing Umbellularia californica basal resprouting response post-wildfire using field measurements and ground-based LiDAR scanning", published in Remote Sensing (https://doi.org/10.3390/rs17173101). The attached .zip archive, Bell_et_al_code.zip, contains the following files and directories: Bell_et_al_code.Rproj – An RStudio project file. Opening this file in RStudio allows the associated scripts to operate in a self-contained working directory that doesn't depend on the user's specific file system. Bell_et_all_ggplot_figures.R – An R script for reproducing all of the plots from Bell et al. 2025. data/ – a folder containing the input data used by the R scripts, containing the following: q1_las/ – LAS point cloud files of California bay laurel resprouts, used to develop a regression equation for estimating resprout biomass from LiDAR-derived volume. q2b_las/ – LAS point cloud files of California bay laurel resprouts from Saddle Mountain, used to test the relationship between fire severity and source tree DBH on resprout biomass. UMCA master data.xlsx – An Excel file containing the master data used by Bell_et_al_ggplot_figures.R generate_voxel_size_fill_data.R – An R script for testing different voxel resolutions and fill levels for estimating resprout biomass. It uses the contents of q1_las/ as input data. output/ – A folder for storing the figures generated by Bell_et_al_ggplot_figures.R sm_tls_volumes.R – An R script for calculating LiDAR-derived volume for bay laurel resprouts from Saddle Mountain. It uses the contents of q2b_las/ as input data. It is recommended that users who download this repository first launch RStudio by double-clicking the file Bell_et_al_code.Rproj, and then opening the associated R scripts within that session. This will ensure that the scripts can be run without having to manually specify a working directory.
