Betula Nana - Dwarf Birke

Betula Nana, generally known as a dwarf birch or polar birch, belongs to the genus Betula and the family of birch plants (Betulaceae). It is particularly characterized by an extreme adaptation to the cold regions of the northern hemisphere.

morphology

The dwarf birch is a small shrub that reaches the height of just about 20 to 60 centimeters. The leaves of Betula Nana are rounded and toothed, and they have a striking green color. The bark of the shrub is light brown and often becomes whitish over time. The male flower kittens of the dwarf birch are cylindrical, while the female flower kitten are shaped.

spread

Betula Nana is at home in the northern regions of the northern hemisphere and extends over parts of Europe, Asia and North America. This plant has also spread in moderate latitudes in higher mountain regions.

Habitat

The dwarf birch prefers cold, subarctic or arctic habitats and can often be found in bogs, swamps, arctic tundians and high mountains. It is a pioneer plant that thrives in extreme environments in which other plants can survive hard.

Ecological meaning

Betula Nana serves as a source of food for various animal species, including reindeer and rabbits. In addition, the dwarf birch contributes to stabilizing soils in extreme environments, since their roots can prevent erosion. It also plays a role in nitrogen fixation, which improves soil quality in such ecologically sensitive areas.

Adjustments to extreme environments

The dwarf birch has developed amazing adjustments to the rough conditions of arctic and subarctic ecosystems. This includes the ability to grow in cold soils and the ability to regenerate on damaged or burned soil. The plant is also able to survive under the extreme light conditions of the north, including the long days of summer and the short, low -light days of winter.
