Abstract
Freshwater biodiversity is under great threat across the globe as evidenced by more severe declines relative to other types of ecosystems. One of the main stressors responsible for these concerning trends is habitat fragmentation, degradation, and loss stemming from anthropogenic activities including energy production, urbanization, agriculture, and resource extraction. Habitat protection and restoration both play an integral role in efforts to save freshwater biodiversity and associated ecosystem services from further decline. In this paper, we summarize the sources of threats associated with habitat fragmentation, degradation, and loss, and then outline response options to protect and restore freshwater habitats. Specific response options are to: legislate the protection of healthy and productive freshwater ecosystems; prioritize habitats for protection and restoration; enact durable protections; conserve habitat in a coordinated and integrated manner; engage in evidence-based restoration using an adaptive management approach; ensure that potential freshwater habitat alterations are mitigated or off-set; and future-proof protection and restoration actions. Such work should be done through a lens that engages and involves local community members. We identify three broad categories of obstacles that arise during the implementation of the response options outlined: a) scientific (e.g., inaccessible data or uncertainties), b) institutional and management (e.g., capacity issues or differing goals across agencies), and c) social and political (e.g., prioritizing economic development over conservation initiatives). The protection and restoration of habitats is key to bending the curve for freshwater biodiversity, with a comprehensive, connected, and coordinated effort of response options needed to protect intact habitats and restore fragmented, degraded, and lost habitats and the biodiversity and ecosystem services that they support.
期刊介绍:
Published since 1993, Environmental Reviews is a quarterly journal that presents authoritative literature reviews on a wide range of environmental science and associated environmental studies topics, with emphasis on the effects on and response of both natural and manmade ecosystems to anthropogenic stress. The authorship and scope are international, with critical literature reviews submitted and invited on such topics as sustainability, water supply management, climate change, harvesting impacts, acid rain, pesticide use, lake acidification, air and marine pollution, oil and gas development, biological control, food chain biomagnification, rehabilitation of polluted aquatic systems, erosion, forestry, bio-indicators of environmental stress, conservation of biodiversity, and many other environmental issues.
