Distribution
Saxifraga rivularis is native to the northern parts of the Northern Hemisphere, where it has a circumpolar distribution, occurring throughout the Arctic and into the alpine climates of mountainous temperate areas, such as the Sierra Nevada in California. It also occurs in the Highlands of Scotland, from which it takes its name, however it is very rare in this area.Streeter et al. (2009), Collins Flower Guide, London, pp.238. It can be found in moist and wet, rocky habitat, in substrates rich in nitrogen and organic material, such as bird rocks and mossy peat flats.{{Cite web |url=https://www.mun.ca/biology/delta/arcticf/_ca/www/sxsxri.htm |title=Flora of the Canadian Arctic Archipelago |access-date=2017-09-11 |archive-date=2007-02-17 |archive-url=https://web.archive.org/web/20070217195634/http://www.mun.ca/biology/delta/arcticf/_ca/www/sxsxri.htm |url-status=live }}
