† Acarospora schleicheri (Ach.) A. Massal, Grimmia orbicularis Bruch ex Wils., Heppia lutosa (Ach.) Nyl., orange cup fungus, Pterygoneurum subsessile (Brid.) Jur., Tortula brevipes (Lesq.) Steere , and Tortula inermis (Brid.) Mont. were present but too rare to analyze.

‡ Codes for microscale positioning of the sampling station: SCN = shrub canopy northside, SCS = shrub canopy southside, and IS = interspace.

§ A lack of a P value indicates that a species was too uncommon to perform indicator-species analysis with power.
