What are some fun facts about trees

10 interesting facts about wood - what you didn't know about the raw material

Wood has been used as a material and fuel in chimneys on our planet for thousands of years. Trees are vital for our global climate and habitat for an infinite number of animal species. We not only use wood as a material for heat generation and as a building material - our culture also lives from paper. Resin may turn into amber and is used in jewelry. The fruits of fruit trees are important sources of food and the basis for the beehives. In addition to all the uses for our trees, we want you to know more Provide facts, that let you see wood from a completely new perspective!

There is also a great variety of woods in Germany

There are almost a hundred different in this country Tree and shrub species. In addition there are the exotic species, which are preferred for decoration in parks and gardens. Around 1400 different species of deciduous trees and 650 species of conifers can be found around the world.

The largest living things? Not just whales!

Trees are also considered to be large living things. If they thrive under favorable living conditions, they will reach heights that exceed the length of a blue whale - with 115 meters the coastal redwood is not only the record holder, but also three times the size of the largest mammal in the world. These heights are made possible by a large, species-related increase in height, a high life expectancy and a protective bark.

Not only huge, but also ancient

Depending on the species and climate, a tree can up to 2000 years to become old. The style oak is thus something like the turtle under the trees. In contrast, the hazelnut looks like a flash in the pan at 100 years of age. When a tree is best for logging also depends on its species. The climate zone also has an influence. While fruit varieties such as cherry trees are “ripe” for the harvest after around 50 years, it takes twice as long for oaks.

The age is visible through annual rings

Everyone knows them, the typical rings in wood. These arise between two growth phaseswhen the seasons change and the tree changes its uptake of nutrients: in spring, after resting in winter, the tree mobilizes all nutrients in order to quickly transport water and build up soft wood. This is how light "early wood" is created. Later in the year the tree forms darker and narrow-pored "latewood" for protection. The annual rings are also influenced by the climate. Favorable conditions ensure wider rings - the tree grows more. The different colors of early and late wood are used to determine the age of the tree.

Distribution of the water over the winter: leaf shedding in preparation

Not only the latewood influences the water transport in the tree when it gets colder. The tree gradually sheds its leaves to the To reduce water evaporation and to keep the precious water in the tree. In this way, the water balance is maintained despite the reduced water absorption at cold temperatures.

The wood is felled in winter

Not only is water uptake regulated in winter, the transport of sap through the main vessels in the tree is also restricted in winter. So the tree prevents through that Formation of harder wood (the latewood) a pest infestation. This natural pest prevention is used by humans for logging. Storage is made easier by the hardwood on the outside and ensures higher quality.

Rubber trees?

There are types of wood that are not dimensionally stable. These woods can be bent or curved lengthways without breaking. When the wood is no longer bent, it returns to its original shape. In this country, among other things, ash, fir and pine are among the elastic woods.

What is the difference between hard and soft wood?

Trees are divided into soft and hard wood by their specific weight. More covered trees, like most deciduous trees, have harder wood than naked trees. These are most of the conifer species. Hard wood is more durable as soft and has one higher calorific value in Fireplace stove or fireplace insert.

How do trees behave in extreme temperatures?

Temperatures below 0 and above 55 degrees that last longer are the temperature limits for trees to grow. The zero point as the freezing point ensures that the water can no longer be transported. Above 55 degrees, so much water evaporates that the tree dries out.

What are woodworms?

In fact, it is Beetle, not worms. The common woodworm is just the larva, which measures between three and eight millimeters. The white larvae that eat their way through the wood and were laid there as eggs are often mistakenly viewed as the full-grown woodworm. The eggs are preferably laid in the early wood of the tree - it is softer and more susceptible to pests. So wood is not just for burning in the stove!
