Your local evidence lens
Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Fire-resistant — location does not change the cited classification.
- Fire-performance conditions
- No test or rating condition is normalized.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 2 source placement records; source schemes remain separate.
- Evidence regions
- Great Basin; Northern Nevada / Great Basin
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
2. Why this plant is relevant here
- State distribution
- No state distribution is normalized.
- Native range
- Current cited native range in AK, AZ, CA, CO, ID, IL, MI, MT, ND, NE, NM, NV, OR, SD, WA, WI, WY.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- USDA hardiness
- No hardiness value is normalized.
3. Legal, ecological, and broader status
- Legal-list status
- Set a location for an exact legal-list result; source silence is not clearance.
- Seed-list status
- Set a location to compare the separate state noxious-weed seed layer.
- Reported invasive here
- No ecological invasive report is normalized; that does not prove noninvasiveness.
- Broader regional context
- Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
- Federal context
- Federal designations remain separate from state legal-list results.
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.

Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and introduced describe biogeographic relationship, not fire performance or planting approval. Doubtful and extinct rows stay visible but do not count as current presence.

The evidence
Recommends (2)
-
“Common plant material options for greenstrips.”
Appendix B row: Thickspike Wheatgrass (Elymus lanceolatus). Origin: Native; lifeform: Sod Forming Grass; relative height: Mid-Tall; seedling vigor: Med.; longevity: Long. Precipitation zone: 8-16 in; soil texture: fine and medium; seeds/lb: 135,000; single-species drill seeding rate: 6 lb/ac; seeding depth: 1/4-1/2 in. Recommended releases: ‘Sodar’, ‘Critana’, ‘Bannock’, ‘Bannock II’.
-
Greenstrips: Another Tool to Manage Wildfire (Fact Sheet 97-36)
“Common perennial plants used in greenstrips and selected characteristics important to their establishment and use”
Table 1 row: Streambank Wheatgrass (Elymus lanceolatus). Minimum yearly precipitation: 8-10 inches; salt or alkali tolerance: Moderate; status: N; growth form, flower color, or season: Sodformer; varieties: ‘Sodar’. The fact sheet says greenstrips should be grazed or mown frequently enough to reduce fuel buildup; otherwise their effectiveness is reduced dramatically.
