Distribution
It has a circumpolar distribution across much of the northern parts of the Northern Hemisphere: much of Canada, the northwestern United States, northern and central Europe, Russia, China and Japan. It is an indicator of alpine tundra and boreal climates. It is found in mountains and moors often with Calluna and grasses.{{Cite web |title=Family Lycopodiaceae, genus Lycopodium; world species list |url=http://homepages.caverock.net.nz/~bj/fern/lycopodium.htm |url-status=dead |archive-url=https://web.archive.org/web/20090227101620/http://homepages.caverock.net.nz/~bj/fern/lycopodium.htm |archive-date=2009-02-27 |access-date=2015-07-27}}{{cite web |title=Species: Diphasiastrum alpinum (Clubmoss, alpine) |url=http://nlbif.eti.uva.nl/bis/flora.php?menuentry=soorten&id=1449 |url-status=dead |archiveurl=https://web.archive.org/web/20110506223021/http://nlbif.eti.uva.nl/bis/flora.php?menuentry=soorten |archivedate=6 May 2011 |accessdate=13 July 2011 |publisher=NLBIF}}[http://bonap.net/MapGallery/State/Diphasiastrum%20alpinum.png Biota of North America Program 2014 state-level distribution map]
