The up-to-date version of these analyses can be viewed here on GitHub Pages!
This repository contains input data and outputs for fire impact assessments within Joshua Tree National Park (JOTR). These analyses support the post-fire reporting requirements of the National Park Service (NPS), with an emphasis on timeliness and accuracy.
| Fire | Date | Historical Overlap | Analysis |
|---|---|---|---|
| Eureka Fire | May 2025 | Yes (includes veg × fire history analysis) | View HTML |
| Black Rock Fire | October 2025 | No (100% previously unburned) | View HTML |
This analysis uses renv for package management using R version 4.4.3. This can be installed using renv::refresh() when inside of the working directory in RStudio.
Alternatively, one can run the analysis in VSCode using:
VSCode- the
Dev Containersextension withinVSCode Docker(Docker Desktop or a preferred alternative)
Then, within the repository in VSCode, run:
Cmd + Shift + P -> Dev Containers: Reopen in Container
When inside the container, to knit / render a Quarto document, run:
Cmd + Shift + P -> Quarto: Render Document, with the desired.qmdfile open.
Or, more simply, from a terminal:
$ quarto render

- Relativized Burn Ratio (RBR): Derived from the Fire Severity Tool by the Schmidt Center for Data Science and Environment.
- Vegetation Polygons: Geospatial data for the Vegetation Mapping Inventory Project of JOTR, provided by the National Park Service (NPS).
- Historic Fires: Historic fires shapefile filtered to JOTR and Mojave National Preserve boundaries, from CAL FIRE.
