4.5 River Basins
Research. Research topics that facilitate appropriate conservation actions include habitat use and preferences, reproductive behavior, fecundity, population dynamics and genetics, feeding, competition, and food web dynamics. Increased understanding of life histories and status helps determine the vulnerability of priority species to further imperilment in addition to identifying possibilities for improved management and conservation. All stud- ies should provide recommendations for mitigation and restoration. Formal descriptions for known or putative undescribed species, as well as investigations aimed at resolving taxonomic status are needed. • Study habitat use and life history characteristics of priority species (e.g., Carolina Ladle Crayfsh, Green Floater, Least Brook Lamprey, Triangle Floater, and V-lip Redhorse).
• Support taxonomic research for priority species (e.g., Cambarus sp. C complex, Chameleon Lampmussel, Mimic Shiner, and the mussel genus Elliptio ).
• Support development of captive propagation techniques for priority species (e.g., Carolina Madtom, Green Floater, Ironcolor Shiner, and Triangle Floater).
• Support genetics research that informs augmentation policy for priority species (e.g., Atlantic Pigtoe, Carolina Madtom, Chameleon Lampmussel, Dwarf Wedgemussel, Green Floater, Ironcolor Shiner, Tar River Spinymussel, Triangle Floater, and Yellow Lance). • Determine impacts of nonnative species on priority species (e.g., Red Swamp Crawfsh and Flathead Catfsh). In addition to the SGCN species found in the basin (see Table 4.83), a list of knowledge-gap priority species is provided in Table 4.84. 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 reg- ulation and prevention of the introduction and spread of exotic or invasive species are vital.
• Support eforts to restore the native aquatic community through reintroduction or augmentation.
• Support acquisition of land that is adjacent to current conservation holdings or priority watersheds.
• Support other regulatory agencies to minimize impacts on species and habitats.
• Support dam removal where appropriate.
