4.5 River Basins
• Determine vulnerability of species across all taxa groups to emerging threats such as endocrine-disrupting chemicals (EDCs) and other compounds present in many of the waterways of the Yadkin — Pee Dee Basin.
• Identify limiting factors of declining species.
In addition to the SGCN species found in the basin (see Table 4.92), a list of knowledge-gap priority species is provided in Table 4.93. Tese are a lower priority for research as com- pared to SGCN for which there are knowledge gaps in the basin. Management Practices. Management practices that reduce impacts and work synergis- tically with other conservation actions are needed to enhance the resilience of natural resources. Particular needs include preserving biodiversity, protecting native populations and their habitats, and improving degraded habitats. In addition, education about, and regulation and prevention of the introduction and spread of exotic or invasive species are vital. Specifc issues in this basin include secondary and cumulative impacts upon water quality, riparian vegetation and stream bank restoration and conservation, mitigation of hydropower development impacts, and species restoration opportunities. • Promote programs to upgrade or increase compliance at wastewater treatment facilities and CAFOs.
