| # FireApproved.com plant flammability evidence directory |
|
|
| Structured plant-flammability evidence from |
| [FireApproved.com](https://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**](https://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](https://fireapproved.com/places/)** — start with where you are. |
| One briefing per state covering what the code adopted there |
| [actually says](https://fireapproved.com/requirements/), cited to the |
| ordinance rather than to a summary of it. |
| - 🌿 **[Plants](https://fireapproved.com/plants/)** — thousands of taxa with |
| every cited rating, browsable [by genus](https://fireapproved.com/plants/genus/) |
| or [by the source that rated it](https://fireapproved.com/plants/source/), and |
| grouped for a place on [Grow](https://fireapproved.com/grow/). |
| - 🏠 **[Materials](https://fireapproved.com/materials/)** — the vents, siding, |
| decking, windows and roofing that are actually listed and tested, with the |
| [standards](https://fireapproved.com/standards/) behind them and a |
| [lapse log](https://fireapproved.com/materials/lapse-log/) for listings that |
| have expired. [Build](https://fireapproved.com/build/) walks the house by |
| assembly. |
| - 📚 **[Learn](https://fireapproved.com/learn/)** — plain-language answers, |
| from [where to start](https://fireapproved.com/guides/hardening-ladder/) to |
| [how to read a plant page](https://fireapproved.com/guides/how-to-read-a-plant-page/), |
| with a [glossary](https://fireapproved.com/glossary/) for the terms the codes |
| use and [the full guide index](https://fireapproved.com/guides/). |
| - 🔎 **[Findings](https://fireapproved.com/findings/)** — the places where a |
| test result or a jurisdiction contradicts what everyone repeats. |

|
|
| > **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/`](https://fireapproved.com/places/) is the state trunk, and |
| > [Build](https://fireapproved.com/build/), [Grow](https://fireapproved.com/grow/) |
| > and [Learn](https://fireapproved.com/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](https://fireapproved.com/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](https://fireapproved.com/llms.txt) · |
| [llms-full.txt](https://fireapproved.com/llms-full.txt) · |
| [every page has a JSON twin](https://fireapproved.com/data/) (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.* |
