Grey Ironbark carries an avoid recommendation on the evidence table. The Eucalyptus paniculata source pack carries the limited evidence notice. A single ecological invasive report is separated from the fire result, and same-form alternatives appear in related plants.

The range evidence route retains distribution context, and broader species browsing is available through the genus index. On paniculata, those routes do not alter the recommendation, add a source row, or turn ecological status into fire support. The accepted evidence keeps the avoid direction visible; cited alternatives remain comparisons only for this ironbark 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.

Native and introduced range evidence

These are exact U.S. botanical-area records from the cited range source. Native and introduced describe biogeographic relationship, not fire performance or planting approval. Doubtful and extinct rows stay visible but do not count as current presence.

The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.

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.
