Name: Sorbus decora - Acer spicatum / Dryopteris carthusiana Shrubland
Reference: Midwestern Ecology Working Group...
Description: This type is only known from Isle Royale National Park in Michigan, where it is restricted to a few outer islands in Rock Harbor at the northeastern end of the park. Stands occupy sites on gentle to moderate slopes at low elevations (under 200 m or 650 feet). Soils are loams to sandy loam, moderately well-drained to well-drained. The vegetation is an unusual type of deciduous forested scrub. Canopy cover varies from 40-90% cover; <i>Sorbus decora</i> is the most abundant canopy tree, <i>Acer spicatum</i> may be codominant, and other less common trees include <i>Abies balsamea, Picea glauca</i>, and <i>Betula papyrifera</i>. Cover of shrubs varies from about 10-70% cover; <i>Oplopanax horridus</i> may be a common understory shrub (but is absent in some places); other common shrubs are <i>Rubus idaeus, Sambucus racemosa</i>, and <i>Taxus canadensis</i>. <i>Dryopteris carthusiana</i> is the most abundant herb; other common herbs are <i>Gymnocarpium dryopteris</i> and <i>Maianthemum canadense</i>. Cover of nonvascular plants is about 5-25%; the most abundant nonvascular plant is the epiphytic lichens called 'old man's beard' or 'hairy lichens' (<i>Usnea</i> spp.).
