One ecological invasive report remains status context outside the laboratory tally. The accepted rows keep the field-device source, range split, limited depth, and ecological report distinct on the pyramidatus account. This organization prevents the distribution or status material from becoming an extra flammability result for the species. The species entry remains the boundary for this four-part reading.

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.
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.
Appendix S5 mean across six grass-form replicates for Sporobolus pyramidatus: MT 505 °C; BL 11.7 cm; BT 27 s; BR 0.49 cm/s; BB 6.00 on the six-category interval scale. Fresh field samples were preheated for 2 min at 150 °C and exposed to the blowtorch for 10 s. The paper gives no directional FL threshold.
5 cited rows from this source; its identity, lineage and tier are stated once.
