Redclaws is rated fire resistant, though the supporting evidence is limited and does not mean the shrub is fireproof.
Fire and Emergency New Zealand classifies redclaws as having low to moderate flammability. That judgment comes from a seven-level system grounded in shoot-flammability testing at Lincoln University, so it reflects how plant samples behaved under controlled exposure. Low and low-moderate ratings fall on the recommended side of that system. Fire Safe Marin separately includes redclaws among the fire-resistant plants common to Marin County, but its publication is an expert-curated guide rather than an experimental rating system.
The two sources therefore reach the same practical conclusion by different routes: one through laboratory-based classification and the other through regional fire-safe plant guidance. Fire Safe Marin also warns that a favorable plant choice still depends on placement, spacing, irrigation, and removal of dead material.
Redclaws is also flagged as invasive in one jurisdiction, so local planting restrictions deserve a separate check before it is added to a landscape.

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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
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.
