Dwarf birch, scientifically known as Betula nana, is a small, shrubby tree native to Arctic and subarctic regions. It typically grows to a height of 1 to 3 feet and features slender, flexible branches. The leaves are small, rounded, and have a serrated edge, turning yellow in the fall. This plant thrives in cold, wet environments, often found in tundra and boggy areas. Dwarf birch plays a crucial role in its ecosystem, providing habitat and food for various wildlife. Its ability to withstand harsh conditions makes it an important species for studying climate adaptation in plants.
