The 2003 tree-leaf resistance ranking is the directional study behind Mongolian oak, Quercus mongolica. A factor analysis of six litter-leaf traits placed 蒙古栎 among the ten taxa with the worst fire resistance. The directory therefore carries an avoid verdict in the evidence table.
The ranked material was cured litter, a detail retained under performance conditions. The remaining rows contain non-rated measurements of leaves and wood, but they do not provide a second recommendation. The record accordingly remains limited evidence.
Review same-form alternatives for comparison, keeping their findings separate from this oak. The linked evidence row preserves the study's author-named category rather than replacing it with a new one.
Highly flammable — location does not change the cited classification.

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.
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.
26 cited rows from this source; its identity, lineage and tier are stated once.
