Bothriochloa ischaemum has two ecological invasive reports. One records an introduced-established status and the other a widespread-invasive status; neither is a fire verdict.
The only directional row lists Yellow bluestem as fire-prone, explaining that such plants may ignite readily and burn intensely. With one source, the record remains a candidate with limited evidence in the evidence table.
Two seed-list entries—one prohibited and one regulated—remain under seed-list status. Range evidence, related plants, and the genus page preserve the existing geographic, comparison, and taxonomic routes. Those channels are displayed separately from the lone fire row.

These source-bound receipts answer only the July 2026 state noxious-weed seed-list question.
This answers only whether the plant identity appears in the July 2026 state noxious-weed seed sheet. It does not establish non-seed plant legal status, ecological-invasive status, nursery-sale rules, or unrestricted use.
NE · Seed-list name scope unresolved. An exact source taxon is governed by “Primary” or an applicable source note, so the qualified row is held instead of publishing an unconditional result. Held source row: usda-ams-state-noxious-weed-seed-2026:NE:005.

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.
Listed as Yellow bluestem — Bothriochloa ischaemum. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
