The applied ecologist's job is often to understand how ecosystem changes impact habitat function. From this understanding we may develop solutions to ecological challenges or place the role of ecosystem components in the greater context of management realms, especially when total restoration is impractical. Two systems where this is the case are salmon in the Central Valley (CA) and Elliott Bay (WA). The Central Valley is a transformed, seasonally-arid landscape that is increasingly susceptible to drought. It also supports human activities that divert water and salmon fisheries increasingly reliant on hatcheries. Elliott Bay in downtown Seattle is an urban waterfront that aggregates human activities along its highly modified shoreline. Despite these stressors, both systems are inhabited by federally listed salmon. In this talk, I will discuss how (1) in the Central Valley, (a) annual rearing windows of juvenile salmon are constrained by its climate and engineered water supply system and (b) fisheries management, flow regulation, and habitat restoration may coordinate to increase productivity of naturally spawned salmon and (2) in Elliott Bay, (a) armoring and overwater structures impair juvenile salmon habitats and (b) the City of Seattle rebuilt its downtown waterfront with science-informed habitat features that attempt to repair these lost habitat functions. By appreciating how ecosystem modifications impact habitat function, we may work within constraints of human activities to improve salmon outcomes.
