HSF, HNF, MonT, VAlp. Also NSW, ACT. A characteristic species of exposed rock crags and ledges of the higher alps.
Occasional specimens of other Rytidosperma species (notably R. oreophilum and R. caespitosum) occurring in similar exposed sites may resemble R. alpicola in the compact growth habit and stiff foliage and care is needed to correctly identify these plants.
