Facts About Trees

Did you know facts about trees? Trees are some of the most important living things on our planet. They are interesting to observe, pleasant to walk next to, and also interesting to learn incredible facts. In our selection – 10 Facts About Trees

Trees didn’t exist 90% of the time of the planet’s life

For most of the planet’s history, which is 4.5 billion years, trees did not exist. They appeared 470 million years ago as mosses without strong roots, and the first vascular plants appeared 420 million years ago and did not grow taller than 1 meter.

In the process of evolution, trees had to “learn” to grow on a trunk and develop a system for transferring nutrients from the root. The first such plants are thought to have been ferns, which had no leaves.


Jurassic Tree

Also facts about trees: Wolemia noble is an evergreen tree that grows 25-40 meters tall. Its remains were found in Jurassic fossils and were thought to be extinct more than 150 million years ago. In 1994, however, trees of this species were discovered in a national park in Australia. Today, about 80 adult trees of this species remain on the planet.

There are more than 60,000 species of trees on the planet

In 2017, a team of scientists compiled all the data from museums, botanical gardens and agri-cultural centers around the world into a single catalog. Thus, it was found that there are now 6,065 species of trees known to science on the planet.


More than half of the tree species are endemics

In addition to the number of known species, scientists also investigated where and how they grow. It turns out that about 58% of all tree species are endemic, meaning they are found only in one region or country. The leaders in the number of endemic species were Brazil, Colombia and Indonesia.

An entire forest of one aspen

In the Fishlake National Forest (Utah, USA), there is an entire forest with a single root system. Pando is a clonal colony of a single tree, as evidenced by DNA testing. The plantation covers an area of 43.6 hectares, and the total weight of the trees is estimated to be 6.6 thousand tons. Pando’s root system is estimated to be 80,000 years old, making it one of the oldest living organisms.

The Tree with Exploding Fruits

The Hura Crepitans, also known as the persimmon tree, is a tree native to the rainforests of South America, recognizable by its smooth, light bark covered with sharp, straight thorns. It can grow up to 60 meters tall and has leaves of up to 60 centimeters. The most famous feature of the Goura is its fruit, which, when ripe, can explode and shoot seeds at a speed of up to 70 meters per second within a radius of up to 100 meters.

The most poisonous tree on the planet

The Mancinelli tree (Hippomane Mancinelli) is considered the most poisonous tree known today – its sap from bark, leaves or fruit contains large amounts of toxins. Even just standing under the tree when it is raining is not a good idea – drops of water with the juice of the leaves will cause a severe allergic reaction on the skin. There have even been known cases where the paint on cars has been damaged.

Da Vinci Hypothesis

Leonardo Da Vinci hypothesized that the thickness of all branches in the crown of a tree is always equal to the thickness of its trunk. Simply put, if you “comb” up all the branches and squeeze them, they will have the same thickness as the trunk of the tree. A scientist from the University of Provence in France has proved by computer simulation that this assumption may be true.

Your own rainforest

Indian arborist Jadav Paeng began planting trees on a sandy wasteland when he was 16. Now the Indian is 47 and has his own 550-hectare rainforest. It is confirmed to be home to Bengal tigers, Indian rhinos, elephants, deer, monkeys and various species of birds.

The foundation of Venice

The last facts about trees: The foundations of the Venetian Islands are made of densely placed wooden piles of alder. Because the wood stays submerged in water, it will not rot or shrivel for more than a thousand years. Moreover, thanks to the minerals in the water, the piles gradually harden.
