We (Jacobs et al. 2021) analyzed an extensive 21- year data set of Chinook Salmon Oncorhynchus tshawytscha redd locations to (1) explain covariation between redd occurrence and environmental variables in the Middle Fork Salmon River (MFSR) and (2) leverage these relationships to predict changes in Chinook Salmon spawning habitat distribution under future climate scenarios. We have since discovered a small but consequential error in the process we used for applying future climate scenarios to our redd occurrence model in pursuit of our second objective: to predict the response of Chinook Salmon spawning to climate change. This error misrepresented variation in mean summer streamflow rates (hereafter, “summer flow”) under the A1B emissions scenario (IPCC 2007) projected to 2040 and 2080 (Hamlet et al. 2013; Isaak et al. 2017), resulting in predictions that were driven primarily by stream temperature change and that underestimated the effects of summer flow changes.
