Typed publication scope: 17 scopes across 15 cited fire sources

Protect Your Home from Wildfire — Fire Resistant Vegetation and Landscaping · Official scoped edition
- AK; partial normalized coverage · 2005-04-27
  Alaska Division of Forestry opens with the wildfire threat to Alaskans and publishes Alaska firewise-landscape examples. FireApproved publishes 58 exact source owners from its 60 taxon entries and holds the taxon-free fern label. State publication scope does not establish suitability for every Alaska climate, site, or home-ignition-zone placement.
Firewise Landscaping for Woodland Homes · Official scoped edition
- AL; partial normalized coverage
  The Alabama Forestry Commission's five-page AFC-FP-04 booklet is an Alabama publication and contains 31 printed suggested or fire-prone plant occurrences. FireApproved publishes 27 exact species or genus owners and holds one infraspecific form plus two named cultivars; this historical source scope does not establish current site suitability for a particular Alabama property.
Fire-Resistant Plants Common to Marin County · Official scoped edition
- Marin County (CA footprint); partial normalized coverage · 2019-01-01
  The publication is explicitly limited to plants common to Marin County. FireApproved publishes 104 exact owners as Marin regional context while retaining its placement, spacing, irrigation, and maintenance boundary. It is not statewide California guidance or parcel suitability.
Firewise Plant Material for the Black Hills · Official scoped edition
- Black Hills (SD footprint); partial normalized coverage
  The page explicitly limits itself to the Black Hills, and NFPA Firewise's archived 2006 plant-list index files it under South Dakota. FireApproved publishes 47 exact genus or species owners from 48 printed rows. This is bounded Black Hills context, not statewide South Dakota coverage or a finding that a plant suits a particular site.
Firewise Plants for the Puget Sound Basin · Official scoped edition
- Puget Sound Basin (WA footprint); partial normalized coverage · 2011-01-01
  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.
Firewise Landscaping Plants (Maryland, New Jersey, and West Virginia editions) · Official scoped edition
- MD; partial normalized coverage · 2015-01-08
  Maryland Forest Service says the list contains plants that can be grown in Maryland and identifies Maryland natives. FireApproved publishes 169 exact source owners from the 180 printed rows; an unrepresentable form and duplicate-owner rows are not broadened. The list calls itself non-comprehensive and does not establish suitability for every Maryland site.
- NJ; partial normalized coverage
  New Jersey DEP publishes a state edition saying the listed plants can be grown in New Jersey and are relatively resistant to fire. Its same 180 printed taxon occurrences map to the 169 conservative owners already normalized for the template family. The list is non-comprehensive and does not establish suitability for every New Jersey site or override the Pinelands Commission's separate placement and fuel-break rules.
- WV; partial normalized coverage · 2026-08-26
  West Virginia Division of Forestry publishes a state edition saying the listed plants can be grown in West Virginia and are relatively resistant to fire. Its same 180 printed taxon occurrences map to the 169 conservative owners already normalized for the template family. The list is non-comprehensive and provides no comparative or site-specific rating.
Wildfire-resistant Landscape Plants for Michigan (Extension Bulletin E2948) · Official scoped edition
- MI; partial normalized coverage · 2007-01-01
  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.
Firewise Landscaping (OSU Extension Bulletin 921) · Official scoped edition
- OH; partial normalized coverage · 2006-03-01
  Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.
Fire-Resistant Plants for Home Landscapes (PNW 590) · Official scoped edition
- ID, OR, WA; partial normalized coverage · 2023-10-01
  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.
Landscaping Can Be Attractive & FIREWISE (Fire Smart Plant List for SC) · Official scoped edition
- SC; partial normalized coverage
  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.
FIREWISE Plant Materials for 3,000 ft. and Higher Elevations (AZ1289) · Official scoped edition
- Arizona at or above 3,000 feet (AZ footprint); partial normalized coverage · 2011-12-01
  AZ1289 is explicitly limited to Arizona elevations of 3,000 feet and higher. FireApproved publishes 69 exact owners as regional Arizona context, retaining every water and elevation condition. It is never promoted to statewide low-desert guidance or an independent Tier 1 vote.
A Compilation of Good Plant Choices for Nevada's High Fire Hazard Areas (SP-05-16) · Official scoped edition
- NV; partial normalized coverage · 2005-01-01
  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.
Landscaping Guidelines to Protect Your Home from Wildfire (SP685) · Official scoped edition
- TN; partial normalized coverage · 2006-10-24
  University of Tennessee Extension SP685 is Tennessee landscape guidance and publishes 78 represented plant owners. Most table rows are a carrier of Virginia Firescapes rather than an independent rating; Tennessee source scope does not change that lineage or establish site suitability.
Virginia Firescapes — Firewise Landscaping for Woodland Homes (430-300) · Official scoped edition
- VA; partial normalized coverage · 2009-04-15
  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.
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34) · Official scoped edition
- 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.
