Giant Sequoia has an avoid result in the evidence table. The record's limited evidence label states how narrow the cited support remains. That depth label stays beside the result so the page neither hides the direction nor overstates the evidence behind it.

Sequoiadendron is a genus-rank umbrella record, keeping the selected facts at the source's named rank. The related plants section supplies cited same-form alternatives without copying this result onto them. Their provenance remains separate, while the cited rows continue to anchor this umbrella's avoid direction and clearly limited support.

      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.

2. Why this plant is relevant here

State distribution
Documented in OR.

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.
