[Please see 50 CFR §16 for regulations regarding Injurious Wildlife]

The summary below shows only wildlife species that are currently listed as injurious and includes updated numbers for taxonomic changes to the species’ names. A few species were originally listed as early as 1900 by Congress (fruit bats and a mongoose), but the Effective Date shown here for those and the other species reflects when the U.S. Fish and Wildlife Service regulations took effect. Congress listed other species by statute after 1900, shown as “C” under “Effective Date.

The regulations cover only live specimens unless otherwise noted. All species of Salmonidae (salmon, trout, char, grayling, freshwater whitefish) are considered injurious due to risk of carrying pathogens that are harmful to fish, unless the salmonids are imported with a health certification or are dead and eviscerated (see 50 CFR 16.13). Twenty genera of salamanders (live, dead, parts) are considered injurious due to risk of carrying the fungus Batrachochytrium salamandrivorans (see 50 CFR 16.14).

(News Release - January 12, 2016 ) Listing Salamanders as Injurious Due to Risk of Salamander Chytrid Fungus 
To help prevent a deadly fungus from killing native salamanders, the U.S. Fish and Wildlife Service published an interim rule to list 201 salamander species as injurious wildlife under the Lacey Act. The fungus Batrachochytrium salamandrivorans, also known as Bsal or salamander chytrid, is carried on the skin of various salamander species.

Common Name Genus Species Number of Species Effective Date
Salamanders (due to risk of Bsal) Genera: Chioglossa, Cynops, Euproctus, Hydromantes, Hynobius, Ichthyosaura, Lissotriton, Neurergus, Notophthalmus, Onychodactylus, Paramesotriton, Plethodon, Pleurodeles, Salamandra, Salamandrella, Salamandrina, Siren, Taricha, Triturus, and Tylototriton 236* January 28, 2016
