Tiger Salamander
Ambystoma tigrinum (Green, 1825)
Amphibians
Ambystoma tigrinum NYS Department of Environmental Conservation
Family: Mole Salamanders (Ambystomatidae)

State Protection: Endangered
A native species in imminent danger of extirpation or extinction in New York (includes any species listed as federally Endangered by the United States). It is illegal to take, import, transport, possess, or sell an animal listed as Endangered, or its parts, without a permit from NYSDEC. 1) Any native species in imminent danger of extirpation or extinction in New York. 2) Any species listed as endangered by the United States Department of the Interior.

Federal Protection: Not Listed

State Rarity Rank: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
In addition to producing noxious secretions, tiger salamanders are able to use their tails to lash out at predators (Brodie 1977).

State Ranking Justification [-]
All tiger salamanders in New York belong to the subspecies Ambystoma tigrinum tigrinum, a unique coastal plain lineage of tiger salamanders that is declining (Church et al. 2003). In addition to being listed as endangered in New York, the subspecies is listed as endangered in the neighboring urbanized states of New Jersey, Delaware, Virginia and Maryland, and it was extirpated from Pennsylvania in the early 1900s (Hulse et al. 2001). In New York, the tiger salamander's range is confined to Long Island, where the development pressure is intense, resulting in highly fragmented islands of suitable habitat. Among the 124 documented breeding locations on the island, surveyors have failed to find tiger salamanders during recent surveys at over a third, another third have viability rankings of fair or poor, and just 13% are considered to support populations with excellent or good viability. The statewide population has been steadily declining since 1980.
