Chapter 3 North Carolina Species
incorporating calcium salts into their shells. This calcium becomes available to higher trophic levels such as birds and mammals.
Due to extremely limited data and a scarcity of biologists who work on the taxa, little is known about the 200+ species of native terrestrial gastropods known to exist in the state or the 30+ introduced species of land snails or slugs. Conservation recommendations for the associated habitats have been incorporated into the natural community descriptions in Chapter 4. Additional recommendations can be found in the river basin descriptions (Section 4.5). The following paragraphs provide information about species identified by the Taxa Team as SGCN or a priority species for research or management, and for which work has been conducted to implement conservation and management recommendations. Numerous land snails were identified as SGCN and knowledge-gap priorities and are listed in Table 3-9. Taxa Team evaluation results can downloaded from https://www.ncwildlife.gov/wildlife-habitat/wildlife-action-plan. Conservation recommendations for the habitats associated have been incorporated into the natural community descriptions in Chapter 4. 3.9.2 Comparison of 2005 and 2015 Priority Species The 2025 Snail Taxa Team evaluated 46 species of aquatic snails and 217 species of land snail species for conservation concern to identify SGCN, knowledge gaps for research priorities, and management priorities. Species could be a priority in more than one of the evaluation categories. The following table provides a comparison of changes to the number of SGCN and priority species between the 2015 SWAP, the 2020 Addendum 1, and the 2025 SWAP. These changes for 2025 do not necessarily indicate a change in concern status for these species; since they are based on more data than in 2015 and were prepared by different experts. 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.
