The Alnus Viridis Subsp. Crispa is commonly known as the American Green Alder as well as Mountain Alder.

The currently accepted scientific name of mountain alder is Alnus viridis (Chaix) DC. subsp. crispa (Ait.) Turrill. Sitka alder, Alnus viridis subsp. sinuata (Regel) A. Love & D. Love, is the other subspecies of A. viridis occurring in North America . The subspecies interbreed where their ranges overlap . Information presented in this text is for mountain alder. LIFE FORM : Shrub FEDERAL LEGAL STATUS : No special status OTHER STATUS : NO-ENTRY

Mountain alder is widely distributed throughout interior, central, and northern Alaska across the Yukon Territory and interior Canada to Labrador, Newfoundland, and Greenland.  It extends south through New England and the Great Lakes States, and into the Pacific Northwest. Disjunct populations are documented in south-central Pennsylvania and west-central North Carolina .

Mountain alder is a dominant or codominant in a variety of habitats.  It may occur as an understory dominant in open conifer forests with black spruce (Picea mariana), white spruce (P.  glauca), lodgepole pine (Pinus contorta), and jack pine (P. banksiana) overstories; and in open and closed deciduous forests with paper birch (Betula papyrifera), quaking aspen (Populus tremuloides), balsam poplar (P. balsamifera), and red alder (Alnus rubra) overstories.  American green alder can dominate in shrub types (often with Salix spp.) and on open, moist tundra .
