Your local evidence lens
Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Highly flammable — location does not change the cited classification.
- Fire-performance conditions
- No test or rating condition is normalized.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 6 source placement records; source schemes remain separate.
- Evidence regions
- Ashland, Oregon; Cape Town, Western Cape, South Africa; Catalonia, Spain; Israel; Marin County, California; Mediterranean France; Mediterranean southeast France; Turkey; Valencia, Spain / western Mediterranean; Yavapai County, Arizona
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 3 scopes across 3 cited fire sources
2. Why this plant is relevant here
- State distribution
- Documented in AZ.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- USDA hardiness
- No hardiness value is normalized.
3. Legal, ecological, and broader status
- Legal-list status
- Set a location for an exact legal-list result; source silence is not clearance.
- Seed-list status
- Set a location to compare the separate state noxious-weed seed layer.
- Reported invasive here
- No ecological invasive report is normalized; that does not prove noninvasiveness.
- Broader regional context
- Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
- Federal context
- Federal designations remain separate from state legal-list results.
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
Recommends (2)
-
“yangına direnci tecrübe edilmiş servi türleri”
The YARDOP circular directs managers to preserve, encourage, or use this named taxon in fire-resistant or slow-burning forest and fire-prevention plantings.
-
מסמך מאגד הנחיות למניעת שרפות ולשיקום יער לאחר שרפות
“מיני העצים שיישארו ייבחרו בקפידה תוך מתן עדיפות למיני חורש ולעצי ברוש”
The guide says retained tree species should be selected carefully, prioritizing woodland species and cypress trees; later buffer specifications again prioritize cypresses over conifers.
Avoids (7)
-
Prohibited Flammable Plants (Ashland Municipal Code 9.04)
“prohibited flammable plant”
The City of Ashland restricts new planting or propagation within 30 ft of any structure, including structures on adjacent lots (AMC 9.04).
-
Jardinería de baja inflamabilidad para las zonas de interfaz urbano-forestal
“named among the most flammable species”
Named in the guide's flammable-species warning: ciprés — accumulates dry branches inside the crown.
-
Fire-Resistant Plants Common to Marin County
“listed as fire-prone”
Fire Safe Marin lists this taxon among common fire-prone plants in Marin County.
-
Sensibilité des haies face aux incendies de forêt sous climat méditerranéen
“Très forte fire sensitivity”
The fiche's overall sensitivity combines experimental-bench inflammability, intensity, and combustion measurements with foresters' observations of fire damage.
-
Débroussaillement — Le Guide Complet : conseils et règlementation
“Les plus combustibles sont celles composées de conifères type “cyprès”.”
The guide warns that cypress-type conifer hedges are the most combustible; ageing trees accumulate dead material and resin that increase combustion.
-
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34)
“Fire-Prone Plants”
Listed as Cypress — Cupressus sp.. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
-
Les franges perimetrals de protecció contra els incendis forestals
“Cal eliminar prioritàriament les espècies més inflamables. — Xiprers — Cupressus sp.”
The guide says to remove this printed taxon first among the more-flammable species when opening and maintaining perimeter protection strips.

Time to extinguish the exotic flame: Lessons from the 2021 Cape Town fire
“Partially burned”
Official-workbook means across 50 leaf trials: fresh ignition 9.079 s, fresh sustainability 49.692 s, dry ignition 2.271 s, dry sustainability 22.186 s, and combustibility 7.73 mg DW s-1. Published Table 1 observation for the 2021 fire: Partially burned.
