The higher stoat numbers reduce the rodent population and the stoats then prey on birds. [6] For instance, the wild population of the endangered takahē dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–2006 mast wiped out more than half the takahē in areas where stoat numbers were not limited by trapping. [7]
The stoat thrived during the Ice Age, as its small size and long body allowed it to easily operate beneath snow, as well as hunt in burrows. The stoat and the long-tailed weasel remained separated until 500,000 years ago, when falling sea levels exposed the Bering land bridge. [20] Fossilised stoat remains have been recovered from Denisova Cave ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
We nearly lost these 23 animals to extinction, but thanks to efforts by conservationists, they have been recovered.

The following is a list of species (or subspecies) in the Mariana Islands, defined by the International Union for Conservation of Nature (IUCN) Red List or by the U.S. Fish & Wildlife Service (USFWS), as being extinct, critically endangered, endangered, threatened, vulnerable, conservation dependent, or near threatened.
Skulls of a long-tailed weasel (top), a stoat (bottom left) and least weasel (bottom right), as illustrated in Merriam's Synopsis of the Weasels of North America. The long-tailed weasel is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of small, burrowing rodents.
