Today, fisheries biologists fear coho salmon face extinction along the Central Coast of California. Is extinction inevitable or can we recover their populations in time? By their nature, coho are reclusive. They enter their streams to spawn when the flows run high and off-color. They prefer the cover of darkness to move upstream and typically build their redds in the most remote stretch of a coastal stream. They spook easy and rarely are seem in their element. Avoiding public awareness seems to be by choice, but their long term survival looks dire without greater awareness on our part.

Protected marine species have populations that are depleted, decreasing, or are at-risk of extinction or local extirpation. As of 2015 The International Union for the Conservation of Nature, a global environmental organization, lists approximately 737 marine species worldwide that are considered at risk of extinction. Many are provided legal protection through national laws requiring research and management measures aimed at recovering and maintaining the species at a sustainable population level. Integral to the policy decision process involving the management and recovery of marine species is the consideration of trade-offs between the economic and ecological costs and benefits of protection. This suggests that economics, at its core the study of trade-offs, has a significant role. In the U.S. a somewhat traditional use of economics in protected species research and management has involved cost minimization or cost-effectiveness analyses to help select or prioritize conservation actions. Economic research has also provided estimates of public non-market benefits of recovering species, which can be used in larger management frameworks such as ecosystem based management and coastal and marine spatial planning. Inherent in much of this research, however, are complex biological and ecological relationships in which varying degrees of scientific uncertainty are present. Addressing this type of uncertainty can affect the economic outcomes related to protected species. For example, recent work suggests that increasing scientific precision in biological sampling and models can greatly affect the magnitude of economic benefits to commercial fisheries, while other research suggests that public non-market benefits of species recovery are sensitive to uncertainty about baseline population estimates. Previous research has illustrated the importance of understanding the biological, ecological, and economic aspects of protected species management and recovery. In this research topic we synthesize current protected marine species economic research and expand the discussion on present and future challenges related to protected species economics. The series of manuscripts brings together an array of prominent researchers and advances our understanding of the ecological and economic aspects of managing and recovering protected marine species.

Rivers host vibrant multispecies communities in their waters and along their banks, and, according to queer-trans-feminist river scientist Cleo Wölfle Hazard, their future vitality requires centering the values of justice, sovereignty, and dynamism. At the intersection of river sciences, queer and trans theory, and environmental justice, Underflows explores river cultures and politics at five sites of water conflict and restoration in California, Oregon, and Washington. Incorporating work with salmon, beaver, and floodplain recovery projects, Wölfle Hazard weaves narratives about innovative field research practices with an affectively oriented queer and trans focus on love and grief for rivers and fish. Drawing on the idea of underflows—the parts of a river’s flow that can’t be seen, the underground currents that seep through soil or rise from aquifers through cracks in bedrock—Wölfle Hazard elucidates the underflows in river cultures, sciences, and politics where Native nations and marginalized communities fight to protect rivers. The result is a deeply moving account of why rivers matter for queer and trans life, offering critical insights that point to innovative ways of doing science that disrupt settler colonialism and new visions for justice in river governance.
