As of 2011 there were proximally 168 different species of frogs and salamanders that suffered extinction or were threatened by it, some populations had 80% of individuals with severe deformities (Kiesecker, 2011). Amphibian endangerment is a serious and highly studied topic in the field of conservation ecology. The rapid decline in genetic variation in wild populations, the decrease of individuals, and extirpation of most populations has required conservation efforts (Richter and Jensen 2005). Conservation ecologists analyze the status of a species and use the best introduction program possible for that species. There are many factors that contribute to the endangerment of a species. However, decline of the species in the wild is primarily because of population isolation, loss of genetic variation, and destruction of habitat. The species of Lithobates sevosus has recently become endangered due to many of these forces. Hence, there is an interdisciplinary recovery team of researchers and agency workers that are attempting to rehabilitate and plan to reintroduce Lithobates sevosus. Upon the review of reintroduction studies and conservation methods the most efficient reintroduction program specific for Lithobates sevosus can be devised. Translocation as a primary recommendation is the most efficient method of reintroduction. For a secondary plan captive breeding and introduction to critical habitats ought to be initiated.
