Typed publication scope: 9 scopes across 9 cited fire sources
Alaska Division of Forestry opens with the wildfire threat to Alaskans and publishes Alaska firewise-landscape examples. FireApproved publishes 58 exact source owners from its 60 taxon entries and holds the taxon-free fern label. State publication scope does not establish suitability for every Alaska climate, site, or home-ignition-zone placement.
City of Ashland (OR footprint); partial normalized coverage · 2026-08-26
This is a City of Ashland adoption fact, not statewide Oregon guidance or an experimental flammability result. FireApproved publishes 24 taxonomy-safe owners as city-level regulatory context. It applies to new planting and propagation within 30 feet of structures, including structures on adjacent lots; it is not projected as a blanket removal order for every established listed plant.
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.
Oklahoma State University Extension frames the article around statewide Oklahoma heat, drought, wildfire, and plant selection and publishes five unambiguous genus owners. Ambiguous common names remain excluded, and the prose examples do not establish suitability for every Oklahoma site.
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.
Western South Dakota, Black Hills (SD footprint); partial normalized coverage · 2026-04-08
The current SDSU Extension page explicitly addresses western South Dakota, particularly the Black Hills. FireApproved publishes its four exact genus owners. This is current bounded regional context, not statewide South Dakota coverage or a finding that every member of a genus behaves alike.
Sun City Texas, Georgetown (TX footprint); partial normalized coverage · 2015-01-14
The guide is authored for the Sun City Texas community in Georgetown. FireApproved publishes 142 exact owners only as community-level context. It is an archived HOA exhibit with unknown rating lineage, not a current statewide Texas source or an independent Tier 1 determination.
University of Kentucky Cooperative Extension and the Kentucky Division of Forestry publish this small-woodland guidance for Kentuckians. FireApproved exposes its 13 exact species or genus owners while retaining the prose-example grain. It is not a scored or comprehensive state table.
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.
Where its sources say to plant it
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.

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.
The City of Ashland restricts new planting or propagation within 30 ft of any structure, including structures on adjacent lots (AMC 9.04). Dwarf or prostrate varieties require Fire and Rescue approval, placement beyond 5 ft, and ordinance-compliant tree or shrub spacing.
Listed as Pine — Pinus 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 table rates Pine — Pinus species very high for flammability hazard, defined as the ease a plant can burn at high temperatures for a prolonged time.
