Yes, birch is consistently rated fire resistant for home landscapes.
Six sources reach the same practical conclusion in Kentucky, Nevada, Utah, Montana, western Washington, and Oregon, Washington, and Idaho. Oregon State, Washington State, and University of Idaho extension specialists list birch as fire resistant. Montana State University and King County’s forestry program do the same, while Kentucky’s extension service names birch among trees and shrubs that work well in defensible space.
The agreement rests mainly on expert-curated plant lists, supported by two compilations. Nevada’s extension service required favorable treatment from at least two named western sources before including birch. Utah State University says Betula species can be firewise when properly placed and maintained, so its finding depends on how the tree is used and cared for. Together, these sources provide consistent landscape guidance rather than a lone local judgment.
Birch is a tree genus in the Betulaceae family, with a listed hardiness span of USDA zones 2a through 9b. The regional breadth does not change the basic message: extension and forestry programs repeatedly place birch among suitable fire-resistant landscape plants. For a homeowner choosing on that basis, the published guidance lands clearly in favor of birch.

Typed publication scope: 9 scopes across 9 cited fire sources
King County's current wildfire page links this list for the Puget Sound Basin. FireApproved publishes 82 exact source owners as basin context, not statewide Washington guidance or a site-specific recommendation.
Michigan State University Extension Bulletin E2948 is explicitly a list of wildfire-resistant landscape plants for Michigan and includes a Michigan-native field. FireApproved publishes 221 exact GBIF owners from 226 represented source rows and holds 15 complex or non-exact rows. This dated publication scope is not a current site-suitability determination.
The April 2022 MontGuide explicitly presents fire-resistant species adapted to Montana. FireApproved publishes 92 exact plant records from the source while retaining excluded genus, family, and unresolved rows; the guide itself says not every listed species grows in every part of the state.
The October 2023 joint Pacific Northwest Extension publication explicitly names Oregon, Washington, and Idaho and publishes more than 150 plant profiles. FireApproved has normalized 155 exact plant records from the source; publication scope does not assert that every listed plant suits every site within the three states.
South Carolina Forestry Commission publishes this explicitly as its Fire Smart Plant List for South Carolina. FireApproved publishes 63 exact genus owners from 72 unique common-name labels; unsafe common-name mappings and duplicates are not broadened. The brochure calls the list non-inclusive and does not establish species-level or site-specific suitability.
University of Kentucky Cooperative Extension and the Kentucky Division of Forestry publish this small-woodland guidance for Kentuckians. FireApproved exposes its 13 exact species or genus owners while retaining the prose-example grain. It is not a scored or comprehensive state table.
University of Nevada Cooperative Extension compiled plants suited to Nevada climate zones and reported favorably by at least two upstream firewise lists. FireApproved publishes 126 exact source owners at Nevada publication scope. The source explicitly makes no independent flammability determination, so these rows remain corroborative.
Utah State University Extension states that this fact sheet selects examples for Utah landscapes and that they require proper placement and maintenance. FireApproved publishes 83 exact source owners at Utah publication scope. The table is not a site-specific planting clearance.
Yavapai County (AZ footprint); partial normalized coverage · 2025-03-14
University of Arizona Cooperative Extension authors Bulletin 34 for Yavapai County. FireApproved publishes 198 exact source owners from its resistant and prone tables and keeps the county boundary visible. County publication scope is regional Arizona context, never statewide scope.

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.
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
Betula species (Birch) is listed under “Trees—deciduous”. The guide says most listed plants require some irrigation during Oregon's dry summer months and must be maintained in a healthy condition.
Listed as Birch — Betula 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.
