Acacia is a genus-rank umbrella record. The evidence table preserves the printed rank instead of treating the umbrella as an interchangeable species record.
The accepted pack also identifies same-form alternatives. Those comparisons remain under related plants, apart from the genus-rank evidence and its limited-evidence result. The source lineage, computed result, and alternatives therefore remain three distinct parts of the record.
The UC Forest Products Laboratory says the guide covers properties of common California landscaping plants and was prepared for California fire agencies. FireApproved publishes 130 exact owners at historical California publication scope. The report is a 1997 compilation, not a current endorsement, site rating, or independent test of every row.

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 fiche's overall sensitivity combines experimental-bench inflammability, intensity, and combustion measurements with foresters' observations of fire damage.
18 cited rows from this source; its identity, lineage and tier are stated once.
