Cyathea australis is named by a resistant and retardant plant reference. That citation establishes the selected lineage for the tree fern and appears among the evidence entries.

The plant is also on-list in the collected recommendations. Its recommendation trail remains identifiable in the listing rows, separate from the named reference used for lineage.

The source coverage is limited evidence. The actual extent of the pack stays visible in the source table, without adding a material condition, method, or result absent from this record.

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.
