Bromus tectorum has one CO legal-list row under the legal-list. Two additional rows are retained on the seed-list, distinct from that regulatory entry.
The fire-source pack is limited evidence, with its extent visible in the evidence table. The three ecological invasive reports accompany those local-list records without becoming fire-performance findings.
The related plants section and range evidence provide comparison and geography outside the selected counts. The genus collection likewise remains broader than this cheatgrass record.
The cited rows keep the fire, legal, seed, and ecological channels inspectable at their own scopes.

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.
Where its sources say to plant it
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

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 Cheatgrass — Bromus tectorum. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
