Abstract

INTRODUCTIONDespite investments of hundreds of millions of dollars annually for more than 20 years to restore freshwater habitat and maximize freshwater production of Pacific salmon Oncorhynchus spp. populations along the West Coast, we still struggle to identify restoration actions within a watershed that will address limiting factors and lead to an increase in habitat capacity and salmon survival. Numerous assessment methods have been developed to identify degraded floodplain, riparian, and instream habitat (Beechie et al. 2013; Roni et al. 2018). Although remote sensing and new analytical techniques have allowed more rapid mapping and assessment of floodplain, riparian, and riverine habitat (Beechie and Imaki 2014; Macfarlane et al. 2017a, 2017b; Bond et al. 2018), reliable methods to adequately quantify historic, current, and potential salmonid abundance at the reach, tributary, and watershed scales have proven more challenging. The scale of watershed restoration and the cost and logistical constraints of measuring fish habitat capacity, current abundance, or survival at both a reach scale and a watershed scale have hampered these efforts.
