Asplenium montanum occurs principally in the Appalachian region, with outlying localities in the Shawnee Hills of western Kentucky (R. Cranfill 1980) and adjacent Indiana (D. M. Smith 1956). A report of its disjunct occurrence on the northern edge of the Ozarks is based on a single specimen whose label indicates the collection locality near Graham Cave, Montgomery County, Missouri. Efforts by several botanists to relocate the population have failed. Reports of a disjunct station in the upper peninsula of Michigan are doubtful.
Asplenium montanum is an ecological specialist. It is typically the sole vascular plant species in the siliceous rock crevices in which it is found. It may occur, however, with two allotetraploid species, A. bradleyi and A. pinnatifidum, which were derived from hybrids of A. montanum with A. platyneuron and A. rhizophyllum, respectively. In addition, A. montanum crosses frequently with A. pinnatifidum producing A. × trudellii and rarely with allotetraploid individuals of A. bradleyi producing A. × wherryi.
