Irena, MO
Irena, MO's wildfire risk, in USFS's own numbers
Irena's 33 buildings earn a 75th-percentile wildfire-risk score nationally under USFS's model — well above the national norm for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Irena at the 77th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
USFS classifies 100% of Irena's buildings as Direct exposure, higher than its 0% Indirect share and far above its 0% Minimal share — a profile where 33 structures sit close enough to vegetation that lot clearing matters most.
Where Irena ranks
Compare Irena's two percentiles: 91st within Missouri, only 75th nationally — a gap of 16 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Irena ranks 7,821 for wildfire risk (1 is highest) and 31,314 by building count (1 is largest). Within Missouri alone, it ranks 92 of 1,062 places by risk. See the full county-by-county picture for Missouri on its state page.
Irena and the insurance market
Irena's 75th-percentile, high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
What would actually reduce this score
Because Direct exposure dominates in Irena (100%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
