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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
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.
“Fire-Resistant Plant Materials for Oregon”
· condition: green
Pinus contorta var. murrayana (Lodgepole pine) is listed under “Trees—evergreens”. The guide says most listed plants require some irrigation during Oregon's dry summer months and must be maintained in a healthy condition.
“high — Pine, lodgepole — Pinus contorta var. murrayana”
Table 1's Fire Hazard column prints “high” for this taxon. The guide calls the rating a rough estimate of potential flammability, not a result of scientific trials. Its footnote says plants that turn brown often become high fire hazards and tells readers to mow grasses and forbs when they begin to turn brown.
