Where is the ecosystem of the ermine?

The ermine, also known as the stoat or short-tailed weasel, primarily inhabits temperate and subarctic regions of the Northern Hemisphere. Its ecosystem includes forests, grasslands, tundras, and mountainous areas, where it thrives in habitats with ample cover and prey availability. Ermines are particularly adapted to colder climates, often found in areas with snow, as their fur changes color with the seasons for camouflage.
