Montane meadows and lakes mostly above 1000 m in the Olympic Mountains (Washington, USA) and the Cascade Mountains (Washington, Oregon, and California, USA), with a few records as low as 73 m. Most populations in California now extinct.


In the Rana boylii group of North American authors. Green, 1985, Herpetologica, 41: 262–267, reported natural hybridization with Rana pretiosa. In the Rana aurora group of Dubois, 1987 "1986", Alytes, 5: 42, in the equivalent Section Amerana, subgenus Aurorana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 322, although Aurorana was shown by Hillis and Wilcox, 2005, Mol. Phylogenet. Evol., 34: 305, to be paraphyletic with respect to Amerana. Reviewed by Altig and Dumas, 1971, Cat. Am. Amph. Rept., 105: 1–2. Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 230–231, provided a brief account, figure, and map (and who commented on the disappearance of this species from large areas of its former distribution). See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 632. Pauly, Ron, and Lerum, 2008, J. Herpetol., 42: 668–679, reported on molecular phylogeography. Pearl and Adams, 2005, in Lannoo (ed.), Amph. Declines: 538–540, and Dodd, 2013, Frogs U.S. and Canada, 2 : 707–715, provided accounts that summarized relevant literature. Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 236–237, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 243, provided an account of larval morphology and biology.
