Black Wattle has a measured fire response, but that measurement does not establish that it is fire resistant.
Black Wattle, Acacia mangium, is a tree in the Fabaceae family. In Potts and colleagues' 2022 study, branches were dried before testing on a grill; the FLAMITS trait database, published by Dryad / Global Ecology and Biogeography, reports 66% estimated burnt biomass.
That percentage describes consumability: how much of the tested plant material was consumed during burning. It is not a measure of how easily the material ignited. The preparation matters, too. These were predried branches, so the result belongs to that material under those test conditions. It cannot by itself tell a homeowner how readily a whole living tree will ignite or how it will behave beside a house.
FLAMITS brings together measurements of different aspects of flammability and retains their experimental context. It does not apply a single threshold that turns these different measurements into a fire-resistance rating. The branch result therefore supports a specific statement about burning, but leaves the planting question open. For someone choosing a tree near a home, a measured amount of fuel consumed is useful information; it is not an endorsement of Black Wattle for fire resistance.

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.
