Helecho acebo is on-list on the evidence table. The Cyrtomium falcatum fire pack remains limited evidence, and 2 ecological invasive reports stay outside the fire result.
The related plants section allows comparison without increasing the accepted source depth. On falcatum, the computed listing, thin pack, and paired status reports keep independent meanings. Returning to the cited rows preserves that boundary whether the record is opened through either common name. A second visit to the evidence table confirms the listing rather than converting either ecological report into fire support. The paired reports retain status-only roles for this fern.

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.
Cyrtomium falcatum is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
