The last article was already about the tree and the devastating consequences of its disappearance. The following text will once again deal with the topic "tree" - it would be a pity to dedicate only one report to it. This time, however, we are leaving the dark sides of deforestation and focusing on exciting, interesting and amazing facts about the tree. Here we go!
Switzerland as a land of trees
The fact that Switzerland offers a variety of tree species at home, is also noticeable when you have no idea about trees. Everywhere offers them a place and thus the opportunity to literally take root - be it on a street somewhere in a city or in your own garden trees belong to us. Depending on the location they are given a very different meaning. So gives the tree on the street this much more charm. The tree in the garden, on the other hand, may offer the cat a refuge or serve as a coveted fruit supplier. Regardless of where and to what extent they occur, trees were and are part of our landscape and our culture.
In the following "Forest Switzerland" offers you some exciting facts about our trees:
1.One third of the land area is covered with forest. He is adorned by about 535 million trees.
2.On the pedestal of the most common trees are the spruce, the fir and the beech.
3.On average, a tree is 100 years old, but the oldest trees actually make it to 1,500 years!
4.The largest tree in Switzerland is Douglas fir from North America with a height of 61 m. You can admire him in Madiswil (BE).
5.If you belong to the suffering plagues whose eyes can no longer be opened due to annoying hay fever, then stay away from the Aspen tree! This produces up to 500 million pollen in spring. Fies!
6.Approximately 5 million cubic meters of wood are harvested per year. Of these, half are sold as "logs" and one third are used as "energy wood". In addition, 150,000 Christmas trees are harvested per year (which are usually disposed of after a few days). How about renting a Christmas tree in a pot instead? For example, at baumfreunde.ch!
7.About 45% of the forest provides valuable protection, e.g. from avalanches or rockfalls.
8.Our forest is considered storage space of approx. 150 million t of carbon!
9.Are you heating your apartment with oil? Why do not you switch to wood then? It can save more than 3 kg of CO2 per liter
The making of a tree
Trees are considered to be very robust and can endure quite a bit (which probably explains their old age). But how do you manage that? To find out, you'll be fascinated by the following facts about the texture of a tree. Have fun!
10.The tree belongs to the wood plants. Here, the trunk serves as a body, which consists of numerous layers, all of which fulfill a specific function.
11.The roots are mostly underground. They provide tree support, absorb nutrients and water. In addition, they act as a storage organ for the stored during photosynthesis starch.
12.Anyone who has ever been allowed to marvel at the cross section of a tree trunk, has certainly noticed that it is made of numerous annual rings. These document the age and fateful years of a tree. Wide rings go e.g. when there is enough rain Thin rings, on the other hand, form due to drought or pest infestation.
13.In the spring, nature comes back to life after hibernating. So are the buds of the leaves, which will adorn the branches of the tree. The leaves or needles not only fulfill their purpose in a purely optical sense, because with the help of photosynthesis, the sugar and starch that are important for the tree are produced.
14.How adaptive the tree is is shown by finding ways to defy climate change. The increased CO2 content in the air results in increased water use efficiency by regulating the stomata in the pores of the leaves to maximize the uptake of carbon while minimizing the loss of water. While this will not affect the amount of greenhouse gases in the atmosphere, according to the WSL research institute, it does show that nature does not simply accept climate change.
Benefits to the environment
Like everything that nature produces, the tree is a small masterpiece or, in his case, rather a masterpiece. It is designed so that it can adapt perfectly to its environment and thus endure for a very long time without further ado. As if this was not enough to become aware of how valuable our nature is, the tree also brings benefits for the environment and, ultimately, for us as well. At the latest after reading the following facts, the tree should be recognized as a true wonder of nature.
15.The tree as efficient CO2 storage. For reasons of growth, trees remove the greenhouse gas CO2 from the atmosphere and thus make an important contribution to climate protection. On average, a single tree binds about 10 kg of CO2 per year. A huge achievement!
16.The tree as part of the water cycle. Trees are responsible for evapotranspiration, i. that water evaporates and causes clouding to precipitate elsewhere. Here, water is taken up by the roots or in the form of raindrops and released again.
17.The tree as a lung of the city. Trees not only filter the air, they also emit vital oxygen. Here, a single tree can absorb up to 5 kg of air pollutants and produce 130 kg of oxygen in the same period.
18.The tree as part of the forest makes an important contribution to the soil reservoir by creating buffer capacities that are available in the rain and thus protect against erosion.
Although the tree occupies a large part of our territory, its existence should not be taken for granted. Trees make up an important part of our environment, bringing with them many useful properties. But not only to benefit from their advantages, I see it as our task to protect the tree as well as possible. In the end, we all benefit from it.
