No, mugo pine is not fire resistant; three forestry and extension sources rate it highly flammable or say to avoid it.
The USDA Forest Service and state Firewise programs place mugo pine in the least favorable category on their four-point scale. Their description identifies it as a landscape shrub with two- to three-inch needles in bundles of two. Virginia Cooperative Extension and Virginia Tech give it an H flammability rating, which means avoid on their three-part scale.
The Nebraska Forest Service reaches the same practical conclusion without assigning a score. Its guidance for the Lean, Clean and Green Area explicitly tells homeowners to avoid mugo pine, along with juniper and arborvitae. The wording and rating systems differ across the eastern United States, Virginia and Eastern Nebraska, but the findings all point away from treating this shrub as fire resistant.
Mugo pine is a low-water shrub in the pine family. It reaches about three feet at maturity, grows in full sun and is hardy to USDA zone 4a. For landscaping near a building, the shared message is clear: treat mugo pine as highly flammable and keep it away from structures.
Nebraska Forest Service labels this the Eastern Nebraska Edition. FireApproved publishes the two exact taxon-resolvable owners from its direct avoid sentence as eastern Nebraska context. Arborvitae and other ambiguous common names remain held; Western Nebraska is not inferred.
Virginia Cooperative Extension's publication opens with Virginia wildfire conditions, identifies its Virginia Firewise Landscaping Task Force, and labels plants native to Virginia. FireApproved publishes 306 exact source owners. Publication scope does not establish parcel suitability or current endorsement of this archived 2009 list.

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.
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 4 · single-value meaning unresolved · whole zone precision · source stated
Source taxon: Pinus mugo · 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.
