What is a cold climate zone that supports some grasses suitable for grazing?

One example of a cold climate zone that supports some grasses suitable for grazing is the tundra. While the tundra is primarily characterized by its harsh, cold conditions and limited vegetation, it does host hardy grasses and sedges that can survive the short growing season. These grasses provide essential grazing opportunities for herbivores like caribou and reindeer. Additionally, certain regions within the subarctic may also support grasslands that are suitable for grazing livestock, particularly during the warmer months.
