Reference:

Description:
This alliance contains red spruce - balsam fir and mixed spruce - northern hardwood forest associations of southeastern Canada ranging to northern New England and New York. The canopy may be dominated by <i>Picea rubens, Abies balsamea</i>, or codominated by both species, with or without northern hardwood species such as <i>Betula alleghaniensis</i>. Typical canopy associates include <i>Betula alleghaniensis</i> and <i>Betula papyrifera</i>, with an understory of <i>Sorbus americana, Acer spicatum</i>, and <i>Acer pensylvanicum</i>. Occasional associates include a diversity of northern hardwoods, such as <i>Acer rubrum, Acer saccharum, Fagus grandifolia</i>, and <i>Tsuga canadensis</i>. Common herbs of this alliance include <i>Clintonia borealis, Coptis trifolia, Cornus canadensis, Huperzia lucidula, Maianthemum canadense, Oclemena acuminata, Oxalis montana</i>, and <i>Trientalis borealis</i>. The bryophyte layer is generally very well-developed, characterized by <i>Bazzania trilobata, Brotherella recurvans, Pleurozium schreberi</i>, and many others. Stands occur primarily on acidic till derived from granites or from sandstone, at elevations from near sea level up to 1370 m (0-4500 feet). Though typically on mesic site, some site are relatively moist ("spruce flats").
