Lesotundra is a harsh climatic zone, it is located in areas of the Earth, which alternate with forest and tundra, as well as swampy areas and lakes. Lesotundra belongs to the southern view of the tundra, because of this it is often called “South”. Lesotundra is located in a subarctic climatic zone. This is a very beautiful territory, where in the spring, largescale flowering of various plants occurs. The territory is distinguished by the variety and rapid growth of mosses, so this is a favorite place for the winter pastures of the northern deer.
Unlike the Arctic and typical tundra, the soil of foresttundra is more capable of agriculture. On its lands you can grow potatoes, cabbage and green onions. However, the soil itself has low fertility indicators:
The most suitable lands for growing crops are the most heated slopes of the territory. But all the same, below 20 cm of the earth layer is a gley layer of the soil, so the development of the root system below 20 cm is impossible. Due to the bad root system, a large number of forest-tundra trees have a curved barrel at the base.
To increase the fertility of such a soil, it will be required:
The greatest complexity is that often these lands of permafrost. Only in the summer the sun warms the soil on average by half a meter. The soil of foresttundra is waterlogged, although the rain falls very rarely on its territory. This is associated with a low coefficient of evaporated moisture, which is why there are many lakes and swamps on the territory. Due to increased humidity and low temperatures, the soil very slowly forms a layer of fertile soil. In comparison with chernozem soil, the soil of the foresttundra is 10 times worse increasing the fertile layer.
The temperature conditions of the foresttundra are slightly different from the climate of the Arctic or typical tundra. The biggest difference is summer. In the forest tundra in the summer, the temperature can rise to +10-14 ° C. If we consider the climate from north to south, this is the first zone with such a high temperature in the summer.
Forests contribute to a more even distribution of snow in the winter, and the wind blows less, in comparison with the usual tundra. The average annual temperature reaches5 …10 ° C. The average height of the winter snow cover is 45-55 cm. In the foresttundra winds blow less intensively than with other tundra areas. The soils near the rivers are more fertile, since they warm the earth, so the maximum vegetation is observed in the river valley.
Characterization of the zone
General interesting facts:
- Constantly blowing winds make the plants press to the ground, and the roots of the trees are distorted, as they have a small rhizome.
- Due to reduced vegetation, the content of carbon dioxide in the air of forest tundra and other types of tundra is reduced.
- Various animals adapted to severe and meager vegetable food. In the coldest season, the northern deer, lemmings and other inhabitants of the tundra eat only mosses and lichens.
- In the tundra of precipitation per year, less in the deserts falls, but due to poor evaporation, the liquid is delayed and develops into many swamps.
- Winter in the foresttundra lasts the third part of the year, the summer is short, but warmer than on the territory of a regular tundra.
- On the territory of Lesotundra, at the beginning of winter, one of the most interesting phenomena can be observed the northern lights.
- The animal world of foresttundra is small, but is highly numerical.
- Snow cover in winter can reach several meters.
- There are much larger rivers along the rivers, and therefore animals too.
- Lesotundra is the most adapted area for plants and animal propagation than a regular tundra.
Lesotundra is a harsh edge for life, to which a few plants and animals have adapted. The territory is distinguished by long winters and short summer. The soil of the territory is poorly adapted for agriculture, the plants do not receive the right amount of fertilizers and other substances, and their roots are short. In winter, a sufficient number of lichens and moss attracts many animals to this zone.
