. Montana amphibian and reptile status assessment, literature review, and conservation plan. Amphibians; Reptiles; Indicators (Biology); Habitat (Ecology); Wildlife conservation. Presence and Status Ranks for Amphibians and Reptiles on USFWS Wildlife Refuges in Montana. Heritage Program status ranks and notations on species presence are listed in the table below for each of the Fish and Wildlife Refuge or refuge complexes in Montana. While some amphibian and reptile species in Montana have undergone declines and/or regional extirpations in recent decades (, Northern Leopard Frog, Western Toad, Greater Short-horned Lizard), none of these species is currently listed or is a candidate for listing under the federal Endangered Species Act of 1973 (ESA) by the Fish and Wildlife Service (16 §1531-1543 (Supp. 1996)). If an amphibian or reptile species in Montana were to be proposed for listing as threatened or endangered under the ESA the decision as to whether the species is threatened or endangered must be made solely on the basis of the best scientific and commercial data and must be judged according to the species status due to the five following factors (1) the present or threatened destruction, modification, or curtailment of its habitat or range, (2) overutilization for commercial, recreational, scientific, or educational purposes, (3) disease or predation, (4) the inadequacy of existing regulatory mechanisms, and (5) other natural or manmade factors affecting its continued existence ( § 1533 (a) (1), (b)(1)). Clearly, it is in the best interest of the species, various state, federal, and tribal agencies, and the general public to take measures to avoid having these factors justify a listing under the ESA. 41.
