While Saskatoon berries do look like blueberries, the plants are far less picky about their soil conditions and are actually more closely related to the apple family. For most of the year, the tundra biome is a cold, frozen landscape. Many tundra species cannot be found elsewhere, and thus the biome is an important contributor to global biodiversity despite its low species number. Those three tundras share almost the same climate, tough conditions, and the same plants. The land is tundra, characterized by permafrost, a layer of soil that remains frozen year-round. The soil of the tundra is also nutrient poor, so it lacks nitrogen and phosphorus two important elements plants need to grow.
