Herptile Species of Greatest Conservation Need

There are 56 native herptile species in Wisconsin. Of these 56 species, 24 (43%) have been identified as Species of Greatest Conservation Need in Wisconsin. Ten of these species are listed as Threatened or Endangered at the state level. Species of Greatest Conservation Need are divided into three groups based on their relative abundance in Wisconsin in comparison with the rest of their range. These divisions address the global role Wisconsin plays in the conservation of these species but leave options open for management.
