Smooth-barked Apple takes its selected lab lineage from the resistant-plant source. The evidence table marks the record as limited evidence. It also carries 1 ecological invasive report, which remains outside the fire evidence for Angophora costata.

The source rows keep the lab lineage and support depth available without turning the ecological report into a vote. A final pass through the cited evidence preserves those roles on the species record. This distinction matters when the ecological designation and fire-performance evidence appear beside each other. That boundary remains visible throughout source review.

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.
