Barley

[Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A405391-1/general-information) accepts Hordeum vulgare as an annual grass in Poaceae. This record represents barley as a species rather than a named cereal cultivar. ## Idaho — BLM fire resistance score 7 The [Southern Idaho master database](https://pocatello.gov/DocumentCenter/View/609/Fire-Resistance-of-Plants--Master-Database-for-Southern-Idaho-PDF), printed page 31, assigns this row score 7. The annual table gives barley 30 by 24 inches, zone 3, full sun and low water. It treats it as a cover crop and calls for mowing or plowing after ripening. The guide says its fine fuel reduces the fire-resistance score. The number does not describe dry, unmanaged barley as a fire barrier. Manage dry growth and unwanted reseeding; the source’s maintenance conditions matter. The numerical score belongs to this regional placement system, not a guarantee of fireproofness; other regional sources remain separate.
