What is a tree line?

The line of a tree or wood is a line in which the trees stop growing. Among the best known are Alpine, Polar, Desert and Tree Line exhibitions, although there are others. In the mountains, this point starts anywhere between 2,600 ft (800 m) and 17,000 ft (5,200 m) above the sea, although between 7,000 ft (2,100 m) and 10,000 ft (3,000 m) is the most typical. The lowest lines of the Alpine trees are in places where it is already very cold and demanding for tree growth, such as North Sweden and Norway, and the highest in Bolivian Andes, where resistant trees grow up to 17,000 ft (5,200 m) above the sea level. These include the ambient temperature, local species and the degree of exposure. Many mountains have lower wood in the south -oriented slopes because they get less sun and are therefore cooler and less hospitable. Usually there are trees that have entered the highest altitude specials of pine because they are best adapted to cold conditions. While alpine forests can host different species of animals, biodiversityIt tends to drop above the tree line, due to lack of food and places that can hide from predators. However, some animals actually live at this altitude, but eat small shrubs. These include mountain goats, alpine Ibex, Bighorn sheep and various rodents and birds including Golden Eagle.

Arctic and Antarctic trees are found in areas that are too far north or south for them to be suitable for tree growth. In general, it is about 70 degrees from the poles, but it can be as close as 52 degrees from the poles depending on the climate. In Eurasia, the tree line is between 66 and 72 degrees north, which means that one of them has only northern tips of Norway, Sweden, Finland and Russia. The northernmost Arctic wood is in the central Siberian plateau where the influence of extreme continental climate warms on the ground and is the southernmost in Quebec where the extremely cold Hudson Bay discouragesfrom tree growth. Few continental meat has reached very far south, making it difficult to delimit the Antarctica line. Most of the southernmost areas of Tierra del Fuego in South America are infertile, with the exception of the host island, located at 55 degrees South, the home of the southernmost trees in the world.
