The range evidence gathers the introduced distribution cited for this grass, while related plants supplies comparison. Those routes do not alter the UT legal row, nine seed designations, or two ecological reports. This separation of channels prevents the regulatory and ecological material from being counted as additional fire findings for C. dactylon.

Plant-specific state seed-list reviews (3)
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.
AL · Seed-list name scope unresolved. An exact source taxon is governed by “Restricted” 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:AL:015. Governing seed section: Restricted; normalized seed-kind scope: state seed list general; applicable note rows usda-ams-state-noxious-weed-seed-2026:AL:044.Official USDA seed requirements.Normalized source record.
MD · Seed listed here. Restricted noxious-weed seed in the reviewed state seed sheet as of 2026-08-26. Additional exact-name source rows have qualified scope and remain held; they do not broaden this published listing. Held source row: usda-ams-state-noxious-weed-seed-2026:MD:034. Governing seed section: Restricted Noxious-Weed Seed in Lawn and Turf Seed and Mixtures; normalized seed-kind scope: lawn and turf seed; applicable note rows usda-ams-state-noxious-weed-seed-2026:MD:031, usda-ams-state-noxious-weed-seed-2026:MD:043, usda-ams-state-noxious-weed-seed-2026:MD:044, usda-ams-state-noxious-weed-seed-2026:MD:045, usda-ams-state-noxious-weed-seed-2026:MD:052.Official USDA seed requirements.Normalized source record.

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 without a rating (11)Corroboration (11 rows from 1 source)
