“…Ecosystem perspectives also stand to facilitate management of other species; enhancing the natural productivity of salmon may benefit the many species that prey on salmon or assimilate their nutrients (Quinn 2018). Overall, as integrative research and management programs are reaching maturity, there is promise in moving toward coordinated, ecosystem-based decisions that benefit salmon (Hare et al 2019).…”

“…Ecosystem-based approaches may enable managers to address environmental imperatives within broader management scopes. Human dimensions are fundamental to decision-making, and ecosystem-based approaches incorporate human dimensions by coordinating across multiple managers and stakeholders (Carwardine et al 2019;Hare et al 2019) and appreciating that perceptions of desirable ecosystem states will vary (Ingeman et al 2019). Addressing a diversity of needs is feasible.…”

Fish face many anthropogenic stressors. Authorities in marine, estuarine, and freshwater realms often share interdependent fisheries management goals, but address singular stressors independently. Here, we present a case study suggesting that coordinating stressor relief across management realms may synergize conservation efforts, especially to actualize restoration benefits. Significant efforts are underway to restore juvenile salmon habitat across California’s Central Valley landscape but it is unclear how fisheries and flow management will influence juvenile salmon occupancy of restored sites. Leveraging monitoring data, we find that for juvenile salmon (<55mm) to actualize benefits of restored habitats will likely require maintaining spawner abundances and flows at or above intermediate values, especially in less-connected portions of the landscape. Furthermore, restoration efforts may prioritize more connected regions to promote use of restored areas, considering that less connected areas are often uninhabited when water and spawners are scarcer. This ecosystem-based framework that evaluates interdependencies of management decisions may be applied to realize natural productivity and enhance conservation in many systems.

“…These studies underscore the complexity of freshwaterocean connectivity. Populations that make more extended use of freshwater have higher exposure to climate stressed freshwater habitats impacted by warming, invasive species, and altered flow regimes (snow/rain, drought, timing/volume) (Crozier et al, 2019;Hare et al, 2016Hare et al, , 2019Williams et al, 2016). The current state of science is clear, southern populations are at greater risk of extinction because of current and future climate conditions.…”

North American salmon once ranged from ocean waters near the Arctic Circle southward to southern New England on the Atlantic and Mexico on the Pacific. The colonial and industrial transformation of rivers and oceans have led to extirpation or endangered status of many southern populations. Today, chronic anthropogenic stressors interact with climate change, which means that effective conservation must address changes in transformed ecosystems. Conservation goals are designed to recover both the species and their habitats. While seemingly congruent, habitat and fish management have different timetables due to speed of changes in climate, habitat, and biological processes relative to regulatory processes, habitat restoration, and project implementation. The Resist‐Accept‐Direct (RAD) framework facilitated exploration of ideas and actions to restore suitable conditions for salmon listed under the Endangered Species Act at their southern edge. Creative and big solutions are needed to recover salmon and RAD provided a way to examine conservation options to sustain salmon in an era of change.

“…They improve communication and provide a transparent method for assessing trade-offs associated with management alternatives and priorities (Granek et al, 2009). They also provide a systematic way to incorporate biogeophysical and socioeconomic information that is key to EBM (Hare et al, 2019;Langhans et al, 2019). Using an ecosystem services approach instead of a fish species focus allows for a more integrative evaluation of functions that need to be restored to TABLE 1 Categorized list of ecosystem services linked to diadromous fishes and their definitions.…”

Diadromous fishes play important ecological roles by delivering ecosystem services and making crucial connections along the watersheds-ocean continuum. However, it is difficult to fully understand the community-level impacts and cumulative benefits of diadromous fish migrations, as these species are most often considered individually or in small groups. Their interactions at a community level (e.g., interdependencies such as predation, co-migration, and habitat conditioning) and the connections between their ecosystem roles and functions (e.g., cumulative marine-derived nutrient contributions, impacts on stream geomorphology) are yet to be fully understood. Similarly, freshwater, estuarine, and marine ecosystems are often considered as independent parts, limiting understanding of the importance of connections across systems. We argue that not considering the ecosystem interdependence and importance of diadromous fish as a community currently hinders the implementation of the large-scale management required to increase ecosystem resilience and fish productivity across the full range of these species. We developed a conceptual model, the Diadromous Watersheds-Ocean Continuum (DWOC), that uses ecosystem services to promote a more holistic approach to the management of the diadromous community and encourages an integrated understanding of the ecosystem connections made by these species. DWOC provides a framework for discussions that can help identify research and management needs, discuss the trade-offs of different management options, and analyze what pressing questions impede the implementation of large-scale management solutions toward a more ecosystem-based management approach.
