Greenbrier, Smilax, Catbrier carries an avoid result in the cited rows. That direction belongs to this record and remains traceable to its sources.
The genus-rank umbrella record belongs to Smilax. The evidence table holds the source at its printed taxonomic level, keeping the result from becoming an automatic species conclusion.
Same-form alternatives are collected under related plants. They help the reader compare other records after seeing the avoid direction and genus scope. The alternative list does not replace either selected fact or add evidence to the umbrella. The reader can inspect those roles in sequence.
The complete three-table AG-874 plant list is explicitly for North Carolina and contains 202 low-, medium-, or high-flammability rows. FireApproved accounts for all source rows under its strict taxonomy and lineage rules; source scope does not establish local suitability at a particular North Carolina site.
Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.

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.
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.
