National NatureServe Conservation Status
Rounded National Status Rank: N4 - Apparently Secure
NatureServe Conservation Status
Rounded Global Status Rank: G4 - Apparently Secure
Reasons: This species is called Echeveria collomae by Kearney & Peebles (1951), and Dudleya saxosa subsp. collomiae by Bailey & Bailey, 1976, Hortus Third. No data is available from floras on abundance or habitat. This G-rank is based on AZHP's evaluation of D. saxosa ssp. collomiae as G4T4? It is my opinion that it should be re-evaluated as G3 because it is restricted to AZ.
