Freshwater biodiversity is under great threat across the globe as evidenced by more severe declines relative to other types of ecosystems. Some main stressors responsible for these concerning trends habitat fragmentation, degradation, and loss stemming from anthropogenic activities, including energy production, urbanization, agriculture, resource extraction. Habitat protection restoration both play an integral role in efforts save freshwater associated ecosystem services further decline. In this paper, we summarize sources threats with then outline response options protect restore habitats. Specific are legislate healthy productive ecosystems, prioritize habitats restoration, enact durable protections, conserve a coordinated integrated manner, engage evidence-based using adaptive management approach, ensure that potential alterations mitigated or off-set, future-proof actions. Such work should be done through lens engages involves local community members. We identify three broad categories obstacles could arise during implementation outlined: (a) scientific (e.g., inaccessible data uncertainties), (b) institutional capacity issues differing goals agencies), (c) social political prioritizing economic development over conservation initiatives).

Freshwater biodiversity loss is accelerating globally, but humanity can change this trajectory through actions that enable recovery. To be successful, these require coordination and planning at a global scale. The Emergency Recovery Plan for freshwater aims to reduce the risk six priority actions: (1) accelerate implementation of environmental flows; (2) improve water quality sustain aquatic life; (3) protect restore critical habitats; (4) manage exploitation species riverine aggregates; (5) prevent control nonnative invasions in (6) safeguard connectivity. These implemented using future-proofing approaches anticipate future risks (e.g., emerging pollutants, new invaders, synergistic effects) minimize likely stressors make conservation more resilient climate other challenges. While uncertainty with respect past observations not concern biodiversity, has distinction accounting conditions have no historical baseline. level unprecedented. Future-proofing will anticipating changes developing implementing address those changes. Here, we showcase successful local case studies examples. Ensuring response options within are future-proofed provide decision makers science-informed choices, even face uncertain potentially conditions.

Managing fisheries in a changing socio-ecological environment may require holistic approaches for identifying and adapting to novel ecosystem dynamics. Using 32 years of Ceded Territory Wisconsin (CTWI) walleye ( Sander vitreus) data, we estimated production P), biomass B), turnover P/B), yield Y), over Y/P) tested hyperstability yield. Most CTWI populations showed low P B, Y/P < 1 . Yet, overharvest > 1) was prevalent among recruitment-based management (natural recruitment (NR), sustained only by stocking, combination). Production, P/B have declined NR populations, while Y remained constant. Walleye hyperstable along gradient all fishery types (i.e., angling only, angling/tribal harvest combined). Diminishing productivity be jointly contributing observed declines. We classified lakes into groups low, moderate, or high vulnerability based on dynamics identify that benefit from declines maintain increase the adaptive capacity walleye.
