This list is an unofficial, non-regulatory list of amphibians and reptiles for which we have little information, are MESA-Delisted, or of suspected conservation concern that NHESP is interested in tracking. Species are included on the list for three primary reasons:

  1. the species is thought to be rare, declining or vulnerable, but there is insufficient information on the condition, number and size of populations to make a determination; 
  2. the species was removed from the official regulatory list, but the Program believes it still is in need of some conservation attention; 
  3. the species distribution and abundance are not well known. These species are on the list to ensure it is tracked while herpetologists determine whether it is appropriate for proposal to the MESA list.
  4. the taxonomic status and associated distribution is poorly understood.

The conservation status of a species is designated by a number (1-5) and preceded by a letter reflecting the appropriate geographic scale of the assessment.  S Rank refers to "subnational" or the local/state status, while G Rank refers to the "global" status (looking at the species as a whole). The numbers have the following meaning:
