The Pteridium file for pteridium joins keep away recommendation. On pteridium, limited evidence sits across that pteridium row. The facts stay as separate jobs on Pteridium. avoid and limited evidence stay split for pteridium.
Use evidence on pteridium for pteridium. The jumps stay with pteridium on Pteridium. On pteridium, pteridium holds avoid beside limited evidence in the pteridium table for Pteridium. On pteridium, pteridium holds avoid beside limited evidence in the pteridium table for Pteridium.
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.
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.
Selective Shrub Management to Preserve Mediterranean Fore…: selectively control in fuel-management bands in mainland Portugal [portugal-selective-fuel-band-control] (with its avoid rating)
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.
Table 2 places this genus in the Control column. The authors describe the control group as heliophilous vegetation associated with fine fuels and traits linked to faster combustibility or greater flammability; this is a selective fuel-band management decision, not a global prohibition.
