fire performance · reviewed: 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.

A municipal prohibition list: the named trees, shrubs, and grasses may not be newly planted or allowed to propagate within 30 feet of any structure (AMC 9.04), with canopy- and shrub-spacing standards under AMC 18.3.10.100. Verdict map: prohibited = avoid. Starred taxa may receive dwarf or prostrate-variety exceptions only with fire department approval, placement beyond five feet, and ordinance-compliant spacing.

Regulatory evidence, not a flammability measurement — an adopted ordinance that corroborates avoid verdicts. Assigned to the pnw590 tree conservatively: an Oregon ordinance in the PNW-guidance sphere has not been demonstrated independent of that lineage, and independence must be shown, never assumed and matters directly to the Oregon audience. Mostly genus-level rows (all pines, all junipers, all cedars), which attach to genus records and leave species-level lab evidence undisturbed. The source's historical Rosmarinus spp. row is held rather than projected onto the much broader modern Salvia genus.
