Since not all of the historical occurrences have been field surveyed, and unsearched potential habitat remains, historically ranked taxa are considered possibly extant, and remain a conservation priority for continued field work. Element has potential to occur in New Jersey, but no occurrences have been reported. In some instances documentation may exist, but as of yet, its source or location has not been determined. Elements erroneously reported from New Jersey, but this error persists in the literature. Also included are rare taxa of uncertain taxonomical standing.
More information is needed to resolve rank.
All historical occurrences have been searched and a reasonable search of potential habitat has been completed. Extirpated taxa are not a current conservation priority. Elements presumed extirpated from New Jersey, but native populations collected from the wild exist in captivity. In other words, the migrant regularly passes through the state, but enduring, mappable element occurrences cannot be defined. Although the SZ rank typically applies to migrants, it should not be used indiscriminately.
