Coverage contract
- fire performance · reviewed: Colorado State University Extension and the Colorado State Forest Service publish Fact Sheet 6.305 for Colorado's WUI and varied ecosystems. FireApproved exposes all 114 exact source owners at Colorado publication scope while retaining score, elevation, water, and Idaho-carrier lineage. Publication scope is not suitability for every Colorado site or zone.
114 ignition-resistant plants scored 7.5-10 on the 0-10 ignitability scale, with the fact sheet's own doctrine that only plants scoring 8, 9, or 10 belong in defensible-space zones 1 and 2. Verdict map: 8-10 = recommend, 7.5 = mixed (below the source's own zone-1-2 bar). The sheet credits "the Idaho materials" as the basis of the scoring, so rows whose scores duplicate the Idaho Firewise master database resolve to that root.
