suspected - based on single observation in 1982 from reliable observer (herpetologist), and an 1889 observation that could be outside YELL.. From Patla and Peterson (2004): "Two unconfirmed observations of Spea intermontana or S. bombifrons are reported for YELL in Koch and Peterson (1995). Searches for spadefoots were conducted on Fairy Creek downstream of Fairy Falls in 2002 (June 21 and Aug. 6), in the vicinity of the last reported observation (1982). No spadefoots have been found during targeted searches or encountered during surveys, and no observations have been reported (to our knowledge). Spadefoots thus remain unconfirmed in YELL."; Data Source: Chuck Peterson, Herpetologist - Idaho State University, Doug Keinath-Lead Zoologist-Wyoming Natural Diversity Database. Observed Summer 2013 near Nez Perce Creek by wildlife staff. Changed to Present: In 2014, a breeding population was confirmed (Schneider et al. 2015). Genetic study confirms and the observations described here have extended the range of the Plains Spadefoot to include Yellowstone National Park.
