the 2020 Addendum 1, and the 2025 SWAP. A comparison with the 2005 SWAP is not included because a different method was used to evaluate and identify SGCN for that version of the Plan.

Some species are a priority in more than one of the three evaluation categories. These changes do not necessarily indicate a change in the concern status of these species. They are more likely a reflection of increases in our knowledge base for the species. The Freshwater Fish Taxa Team recognized some species propagated in fish hatcheries and released into freshwater systems have naturalized with native populations. For most of these comingled species, it is difficult to separate the populations during surveys or monitoring activities. The Taxa Team designated which populations were evaluated by indicating “native” or “naturalized” as the population unit. This applies to Alewife, Blueback Herring, Brook Trout, Brown Trout, Muskellunge, Smallmouth Buffalo, Striped Bass, and White Perch. The Taxa Team also recognized that some populations should be evaluated based on the ecoregion or river basin where they occur because they are subject to different threats and pressures.
• American Brook Lamprey were evaluated as separate Mountain and Piedmont populations; however, both population segments are SGCN.
• Broadtail Madtom populations in Lake Waccamaw, Cape Fear River and Pee Dee River basins were evaluated and designated as SGCN.
The following sections highlight specific conservation issues related to SGCN and their habitats. This is not an exhaustive list of species-specific conservation concerns but rather highlights some of the concerns in the state. Recommendations for priority survey, monitoring, and research studies, conservation actions, and partnerships are outlined in Section 3.5.8. 3.5.3 Conservation Concerns Table 3-4 (Appendix 3) provides a list of Freshwater Fish SGCN and priority species. River basin and aquatic habitat associations for these species are provided in Table 3-18 in Appendix 3.
