“…Approaches that use generic structural connectivity measures (i.e., total accessible stream network length) as proxies for habitat gain result in less efficient, more costly solutions (Sethi et al, 2017;Rodeles et al, 2020), prompting calls to move towards functional connectivity measures in dam prioritizations (Branco et al, 2014). Increasingly, prioritizations have utilized functional connectivity measures representing fish diversity, richness, populations, and life history traits (Erős et al, 2018;Ioannidou and O'Hanley, 2019;McManamay et al, 2019;Kemp et al, 2020, King et al, 2021, but attempts to address functional connectivity in dam prioritizations incorporating habitat suitability for individual species have often relied on species ranges. However, relying solely on species range data can result in large potential commission errors and inadequate estimates of habitat overlap with invasive species, as all stream habitat accessible within a species' range is treated as equally suitable (McKay et al, 2017) irrespective of differences in actual habitat quality of different stream segments.…”
