FireApproved.com plant flammability evidence directory

Structured plant-flammability evidence from FireApproved.com, a citation directory for wildfire-resistant construction and plants. The site issues no ratings of its own. Every status is computed from cited evidence.

• 3,801 plant records / 27,007 evidence rows, plus the 130-source registry those rows are attributed to.
• Each row keeps the source's own wording, the edition, and the date the document was read. Classifications are computed by a published rule (lineage, not row count; direct fire evidence is never silently outvoted by curation).
• croissant.json is Croissant 1.1, validated with mlcroissant.
• Canonical: https://fireapproved.com/plants/ — the .json replaces the page's trailing slash, so /plants/{id}/ is JSON at /plants/{id}.json.
• Snapshot: https://github.com/grysngrhm-tech/fireapproved-data/releases/tag/v2026.08.25
• Coverage: source documents dated 1968 through 2026-08-25 (23,103 of 27,007 rows carry a document date). 130 sources in the United States, Europe, the Mediterranean, Australia, New Zealand, South America, and other named regions. Not a global flora census.
• Methodology: https://fireapproved.com/methodology

This is one of two FireApproved.com datasets. The materials census is a separate repo (osfm-bml-censuses). The 5-row ORSC R327 table is not posted standalone.

Dataset viewer

The Hub viewer is pinned to the two CSVs (evidence and sources). croissant.json is Croissant 1.1 metadata, not a table. plants-evidence.jsonl and plant-sources.json are lossless twins.

Recompute a classification

recompute-plant-class.ipynb loads the CSV, runs the published rule, and compares three plants (abelia-floribunda, kalopanax-pictus, zygophyllum) to the live JSON twins. It does not assign ratings.

About FireApproved.com

Every wildfire plant list contradicts the next one, and almost none of them say why. One extension bulletin calls a shrub fire-resistant, the next calls it a hazard, and neither shows its work.

FireApproved.com is where you find out what is actually behind the advice. Look up a plant and you see every source that rated it, the exact words each one used, when it was published — and where they disagree, laid side by side instead of averaged into one anonymous verdict you have to take on faith.

It covers the whole decision, not just the planting list:

• 📍 Places — start with where you are. One briefing per state covering what the code adopted there actually says, cited to the ordinance rather than to a summary of it.
• 🌿 Plants — thousands of taxa with every cited rating, browsable by genus or by the source that rated it, and grouped for a place on Grow.
• 🏠 Materials — the vents, siding, decking, windows and roofing that are actually listed and tested, with the standards behind them and a lapse log for listings that have expired. Build walks the house by assembly.
• 📚 Learn — plain-language answers, from where to start to how to read a plant page, with a glossary for the terms the codes use and the full guide index.
• 🔎 Findings — the places where a test result or a jurisdiction contradicts what everyone repeats.

Start here: fireapproved.com · where you are · the plant directory · the materials directory · how this is built

Changed since the 2026-08-25 snapshot. The site reorganized around location on 2026-08-26. /states/, /plants/state/ and /plants/zone/ are gone; /places/ is the state trunk, and Build, Grow and Learn are the three branches off it. Record URLs in the data files (/plants/{id}/, /materials/{id}/) did not move, so rows published against the earlier snapshot still resolve.

Why this data is worth citing

The site issues no rating of its own. Every status is computed from cited evidence by a published rule, and four properties make that reproducible:

1. Every verdict keeps the source's own words — its phrasing, its edition, and the date the document was read, not a label invented later.
2. Classifications are computed, never hand-assigned. See the methodology.
3. Evidence deduplicates by lineage, not by row. A rater who republishes the same finding in five places counts once, so a widely-copied opinion cannot outvote a laboratory result.
4. Conflicts are preserved, not averaged. When sources disagree the record says so and shows both sides.

The source registry ships alongside the evidence, so you can recompute or re-weigh every classification yourself rather than trusting ours.

The live site is the source of truth and is always current. Machine-readable entry points: llms.txt · llms-full.txt · every page has a JSON twin (the .json replaces the trailing slash).

FireApproved is a citation directory. It is not a listing body, an insurer, or a building official — verify at the source before you specify.
