What is Birch's family?

Birch's family is a family of trees and wood shrubs, scientifically classified as a family betulation. Rod Betula is a parental family for real birchs, although modern science generally recognizes two solets in a birch family, six genera and approximately 130 species. These include birch, alder, horny and several trees carrying nuts such as Filbert and Hazel. Birchs have long been important for wood and nuts they produce.

It is assumed that this family of trees came in prehistoric China, because there are all six families and more than 50 species in this area, many of which are endemic for the region. Examples of fossil examples from this area of ​​all six families reach up to 20 million years. Today, these trees are found in almost all mild zones around the world, especially in the northern hemisphere, although several species are known from Andy Mountains in South America.

Many Birch Family members are considered a pioneering species. These types of trees are often the first to establish themselves in the areah cleaned fires and other disorders. They can colonize terrain like Heathland and wet lowlands because many species tolerant of wet conditions. Most members of the birch family have tears with feathers and serrated edges. All of them are monoecious or have male and female flowers on the same tree.

Birch family members have long been commercial for nuts, timber and other wooden products. Filberts and hazelnuts are important food crops. Pre -industrial nations, such as native Americans, used birch bark to cover canoes and dwellings and as a medium for writing and painting. Wood from some species, such as Hornbeams, is particularly hard and durable and is used in the past for things like tools, cars and chopping boards.

Today, Alder and Birch remain popular for furniture, lining, hobbies and veneers. Much of plywood or cabinet is made from the outer layer of birch. Extracts of someErine species are used in cosmetics, shampoos and flavors and birch beer is a traditional soft carbonated beer. Birch is also popular wood because it burns purely and has a high caloric value for its weight. Wood from species, such as Hornbeam, is still used to construct objects such as tool handles, wooden pins and floor, for which very hard and durable wood is desirable.
