Cheilanthes sieberi has a resistant and retardant plants reference as its selected lineage. The source is retained with the cited evidence for this fern record.

An on-list recommendation accompanies that lineage. The citation supporting the list entry stays identifiable in the recommendation rows, rather than being merged with the role of the named plant reference.

The available pack remains limited evidence. Its scope can be checked in the source table, without supplying a material condition, method, or numeric result absent from the selected facts.

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.
