Typed publication scope: 6 scopes across 6 cited fire sources
Marin County (CA footprint); partial normalized coverage · 2019-01-01
The publication is explicitly limited to plants common to Marin County. FireApproved publishes 104 exact owners as Marin regional context while retaining its placement, spacing, irrigation, and maintenance boundary. It is not statewide California guidance or parcel suitability.
Southern Idaho (ID footprint); partial normalized coverage · 2013-11-08
The official database labels itself "For Southern Idaho" and describes Idaho residents at the urban-rangeland interface. FireApproved publishes 419 existing plant owners that cite its scored rows. This bounded Southern Idaho scope is regional context, not statewide coverage or a conclusion that the score transfers unchanged to every Idaho site.
LSU AgCenter calls these 31 ornamentals commonly used in Louisiana and recommended for Louisiana firewise landscaping efforts. FireApproved publishes 31 exact source owners, mostly at the source's genus grain. Undocumented curation remains corroborative and is not site suitability.
South Carolina Forestry Commission publishes this explicitly as its Fire Smart Plant List for South Carolina. FireApproved publishes 63 exact genus owners from 72 unique common-name labels; unsafe common-name mappings and duplicates are not broadened. The brochure calls the list non-inclusive and does not establish species-level or site-specific suitability.
University of Nevada Cooperative Extension compiled plants suited to Nevada climate zones and reported favorably by at least two upstream firewise lists. FireApproved publishes 126 exact source owners at Nevada publication scope. The source explicitly makes no independent flammability determination, so these rows remain corroborative.
Yavapai County (AZ footprint); partial normalized coverage · 2025-03-14
University of Arizona Cooperative Extension authors Bulletin 34 for Yavapai County. FireApproved publishes 198 exact source owners from its resistant and prone tables and keeps the county boundary visible. County publication scope is regional Arizona context, never statewide scope.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.
FireSmart BC Plant Program: suitable for HIZ extended zone (30-100 m) [FireSmart BC Home Ignition Zone] (with its recommendation)
Fire-Resistant Plants for Oregon Home Landscapes: Oregon [osu-frn6-oregon-regions] (with its recommendation)
Fire Resistance of Plants Master Database: 50-60 ft minimum planting distance on flat terrain [Idaho minimum planting distance] (mid-scale rating)

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
“Fire-Resistant Plant Materials for Oregon”
· condition: green
Ligustrum species (Privet) is listed under “Shrubs—broadleaf evergreen”. The guide says most listed plants require some irrigation during Oregon's dry summer months and must be maintained in a healthy condition.
Listed as Privet — Ligustrum sp.. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
The fiche's overall sensitivity combines experimental-bench inflammability, intensity, and combustion measurements with foresters' observations of fire damage.
