populations or establish new populations in suitable habitats. None of these approaches are without risks, such as reduction of genetic material and inbreeding, introduction of disease from individuals released into the wild, and loss of species held captive from human error or equipment failure (Snyder et al. 1996; USFWS 2000; Lysne et al. 2008) , but these must be balanced against the extremity of threat to both the species in question and the taxon as a whole . 3.9.6 Threats and Problems Chapter 5 describes 11 categories of threats the Taxa Team considered during the evalu- ation and ranking process to identify SGCN; information about the expected scope and severity of the impacts from these threats is available in Appendix G. Since there is a sig-
nifcant lack of information about aquatic and land snails in the state, the evaluation results for Metric 9 do not adequately assess anticipated impacts from threats for nearly all species considered during the evalua- tions. Te results do indicate the threats most likely to create signifcant impacts on populations of Magnifcent Rams-horn and Greenfeld Rams-horn in North Carolina over the next 10 years include the following:
