Stipa tenacissima has an avoid recommendation in the evidence table. The finding leads the stipa profile and stays attached to this individual species record rather than every member of the genus.
The fire-source set is limited evidence. The cited material exposes that depth without adding a performance condition or a second source conclusion beyond the accepted record.
Same-form alternatives are collected among related plants. They create a useful comparison route for the avoid finding while retaining their own evidence and recommendations, rather than serving as extra support for this record or the wider genus.
Highly flammable — location does not change the cited classification.

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.
