The limestone blue wattle record is on-list in the evidence table. Its selected citation is the fire-resistant and retardant plant source, and the page labels the result limited evidence. This treatment reports a named list placement for Acacia caerulescens without manufacturing a test threshold or additional lineage. A performance number is not supplied.

The source row remains available for a second reading of that boundary. The comparison choices sit under related plants; the genus page supplies the wider genus frame while leaving this limestone blue wattle entry attached to its own citation.

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.

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.
