   Notes: Values are presented as percentage declines in distribution: positive values represent distribution declines and negative values represent distribution expansion.  Nomenclature follows Nelson et al. (2004).  Note: (1) cutthroat trout (Oncorhynchus clarkii) is native to the upper basin but nonnative to the lower basin and was not included in the analysis; (2) if a species was recorded in a stream segment post-1980 and was absent from the segment pre-1980, the species was considered to be historically absent.  Importantly, this method will produce lower estimates of native species decline compared to estimates assuming historically presence.    

† C. macularius and M. coriacea are not extinct from the lower basin, but are estimated as exhibiting a 100% decline because the database does not contain recent records of their occurrence.
