Aulacomnium palustre
''Aulacomnium palustre'', the ribbed bog moss or bog groove-moss, is a moss that is nearly cosmopolitan in distribution. It occurs in North America, the Dominican Republic, Venezuela, Eurasia, and New Zealand. In North America, it occurs across southern arctic,〔"Arctic" refers to treeless areas underlain with continuous permafrost; "subarctic" refers to mixed tundra and open forest underlain with discontinuous permafrost.〕 subboreal,〔"Subboreal" refers to areas in southern Canada, the Great Lakes states, and the Northeast that were once underlain with permafrost that has since melted.〕 and boreal〔"boreal" refers to northern coniferous forests where permafrost occurs only sporadically.〕 regions from Alaska and British Columbia to Greenland and Quebec. Documentation of ribbed bog moss's distribution in the contiguous United States is probably incomplete. It is reported sporadically south to Washington, Wyoming, Georgia, and Virginia.
==Habitat types and plant communities==
Ribbed bog moss is frequent in arctic to subboreal wetlands. Moss assemblages are typically diverse in northern (arctic, subarctic, and boreal) plant communities, and individual moss species often have low cover and/or frequency. Moss species with coverages of 2% to 4% can be common to dominant in boreal communities, although ribbed bog moss attains coverages as great as 40% in some boreal communities.
Ribbed bog moss grows in open and forested wetland communities. In unforested northern communities, ribbed bog moss is found in sedge (''Carex'' spp.) meadows, sphagnum (''Sphagnum'' spp.) peatlands, heath-sedge fens, and willow (''Salix'' spp.)-dominated fens. In forests, ribbed bog moss grows in the ground layer of boreal and subboreal white spruce (''Picea glauca''), black spruce (''P. mariana''), mixed spruce-tamarack (''Larix laricina''), and jack pine (''Pinus banksiana'') fens and bogs of Alaska, Minnesota, and Canada and in boreal spruce-birch (''Betula'' spp.) forests of Alaska and northwestern Canada. Mosses are abundant in taiga forests of interior Alaska and Canada, forming characteristic strata in nearly every taiga forest type.
Less is known of ribbed bog moss associations south and east of Minnesota, although ribbed bog moss has been noted in some swamp, coniferous and/or hardwood bog, and grassland communities. Ribbed bog moss grows in red maple (''Acer rubrum'') swamps of Long Island, New York, and Little listed ribbed bog moss as common (1-4% frequency) in Atlantic white-cedar (''Chamaecyparis thyoides'') swamps of southern New Jersey.〔Little, S. 1951. Observations on the minor vegetation of the pine barren swamps in southern New Jersey. ''Bulletin of the Torrey Botanical Club''. 78(2): 153-160.〕 Ribbed bog moss is also common in jack pine, aspen (''Populus'' spp.), and mixed-hardwood forests of the Great Lakes states and southern Canada. Ribbed bog moss grows on tallgrass prairie in Kansas and Arkansas. In the Pacific Northwest ribbed bog moss occurs in alpine, subalpine, wet and dry coniferous forest, and open peatland communities. In a survey of alpine and unforested subalpine communities of the North Cascade Range in Washington and British Columbia, ribbed bog moss occurred in graminoid, forb, heath, and willow communities.
