The relative influences of total precipitation and air temperature on the annual low streamflow extremes are quantified from 42 Pacific Northwest stream gauges from 1948 to 2013 using mean annual streamflow as a proxy for precipitation amount effects and streamflow center of timing as a proxy for temperature effects on low flow metrics.
These risk maps for economically and ecologically important invasive species provide land managers with information to assess the potential for species introduction, establishment, and landscape susceptibility.
