If these values could not be determined for a species, then the species was categorized as data deficient and was not further evaluated for potential listing. One exception to this procedure occurred for species that are limited to 1 2 populations in North Carolina. These species are considered inherently susceptible to stochastic (unpredictable) threats and were therefore assigned to the highest threat category. Once the rarity, trend, and threats were identified or assigned for a species, the trend and overall threat values were incorporated into a listing criteria matrix associated with the number of viable populations recorded for that species. There are three protected plant listing criteria matrices and each species is assigned to one of them based on the number of populations of good viability recorded in North Carolina for that species: (A) 1 5, (B) 6 19, or (C) >20 populations of good to excellent viability. The possible outcomes from the listing criteria matrices are Endangered, Threatened, Special Concern Vulnerable, or Significantly Rare. Only Endangered, Threatened, and Special Concern categories warrant listing on the North Carolina Protected Plant Species List. Species evaluated as Significantly Rare through this process are not added to the state list of protected species; however, they remain on the NHP Rare Plant List which does not have any regulatory authority. The Scientific Committee determined through this process that any tracked species with extant populations in North Carolina, but none of good to excellent viability (A , B , or E ranked populations) would be listed as Endangered. Further, any tracked species with only extirpated (X ), historical (H ), and failed to find (F ) ranked populations in North Carolina would be listed as Special Concern Historical.
