Least Weasels Rare in Wyoming
LEAST WEASELS: State law lists the “weasel” as a furbearer. Three weasel species exist in Wyoming: long-tailed weasel, short-tailed weasel (ermine) and least weasel. The least weasel is very small and its fur has negligible value. The species is quite rare and little is known concerning distribution. Trappers are asked to make every attempt to avoid trapping the least weasel. The Wyoming Fish and Game Department requests that unintentional trapping of a least weasel be reported to the Nongame Section in an effort to preserve the specimen for scientific use.
The easiest way to distinguish the least weasel from the short-tailed and long-tailed weasel are by looking at the tail. Both the short-tailed and long-tailed weasels have a black tip on their tail. The least weasel is missing this characteristic and has NO black tip on the end of its tail. Please report any sightings to either us or your local game warden so that more information can be gathered on the population dynamics and locations of these unique predators.
Unfortunately traps are indiscriminate and will capture least weasels just as easily as long-tailed or short-tailed weasels. Due to the lack of trapping restrictions and the rarity of this species, least weasels may be extirpated from the state before data on their locations can be collected.
