Northern boreal species, particularly red spruce, become apparent on peaks in the northern part of the M&M Trail. The high, exposed ledges of Mount Monadnock support several alpine and sub-alpine species of plants, including mountain ash, cotton grass, sheep laurel, mountain sandwort, and the mountain cranberry. Krummholz, trees stunted by harsh weather, are found on Mount Monadnock, as are several alpine bogs.
