Sweet cherry is rated fire resistant, and all three published judgments support recommending or retaining it.
The USDA Forest Service Northeastern Area and state Firewise programs rate sweet cherry at the favorable end of their four-category scale. They also describe it as an invasive tree that birds spread into natural environments and note that fruiting cherries are forms of this species. That warning does not change the fire rating, but it fits with sweet cherry being flagged as invasive in two jurisdictions.
Catalan guidance reaches a similar result in two ways. The Diputació de Girona and Bombers de la Generalitat de Catalunya rate Prunus avium “muy recomendada,” the highest of five garden-suitability verdicts. For sweet cherry, that judgment assumes species-specific care and balances fire-resistance research with fuel structure, maintenance, origin, invasiveness, and fire-service experience. The Diputació de Barcelona and CREAF also name it among the less-flammable species to maintain first when opening and maintaining perimeter protection strips.
The agreement is useful because the judgments do not ask exactly the same question. One assigns a Firewise category, one weighs broad suitability for fire-adapted gardening, and one directs species selection in perimeter strips. Together they support treating this tree, which reaches about 50 feet at maturity, as fire resistant. Its invasive status remains a separate concern when deciding whether it belongs in a particular 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.
Plant hardiness evidence
These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA
Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value
is not treated as a tolerance range. Different source boundaries stay separate: overlapping
statements are compared independently, while only ranges with no shared zone are called a conflict.
Source prints 5 · single-value meaning unresolved · whole zone precision · source stated
Source taxon: Prunus avium · exact match.
Source location: Cold Hardiness Zone field in the recovered selector record.
Not used for comparison: The recovered selector prints one Cold Hardiness Zone value but does not define it as a minimum threshold or a one-zone range.
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.
Prunus avium is rated “MUY RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
