Interesting facts about the elm

The plant genus of elm trees (Ulmus) includes about 30 different species, of which Bergulme, elm and elm just three are native to Europe. In terms of temperature compatibility, elms have a typical preferred for most deciduous trees heat area. They are found only in the northern hemisphere in warm temperate zones. However, the elm is species-rich only in Asia, where two thirds of all elm species are native.
Elms can be identified relatively easily by their mutually arranged leaves. While most deciduous trees have a paired arrangement, elm leaves on the branches alternately layer on top of each other.
In the last hundred years, a large part of the elm trees worldwide have fallen victim to two types of toadstools. Here are infected with the fungus elm beetle as a carrier. When drilling into the wood, they transfer the fungus to the tree, which then loses its ability to transport water over time. As a result of the lack of water all elm leaves die and photosynthesis succumbs. In the recent past, attempts have been made to combat the progressing elm dying by breeding resistant elms.
