Vincetoxicum nigrum has 2 prohibited legal-list rows for IN and OH in the regulatory record. Those state restrictions are kept apart from its fire-related measurement.
The only fire row reports 3391.61 kcal/kg for live leaves that were predried and measured with a calorimeter. No recommend-or-avoid threshold accompanies that value, leaving the page a candidate with limited evidence in the evidence table.
The lower-48 ecological report uses widespread-invasive status. Twenty range rows separately document introduced occurrences. Those channels do not direct the fire banner; the cited measurement remains the sole fire-evidence basis.

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.
