Ash trees in the Czech Republic are widely destroyed by a disease caused by the microscopic calara fungus. It is invisible to the human eye, but it can easily destroy even a thirty-meter tree. It spreads like a virus and there is no defense against it. Ash trees are gradually disappearing from the landscape.

“At first glance, it’s pretty clear that the tree is 99 percent leafless and is starting to look completely dry,” says Kateřina Jánská, who tends the lawns at Chrudim. The city’s ash trees are also dying, and if their condition deteriorates significantly, they cannot be saved. “If the tree is already in such a state, the chance of saving it is zero,” he says.

Chalara is taking the Czech forests by storm. They also noticed problems in the Iron Mountains. In some locations, the onset of the disease is very rapid.
“It depends on the location, somewhere it develops faster, and the tree is usually attacked by other fungi, such as Wenceslas and the like. As a rule, within two to three years, the tree is at a stage where there is a danger of falling. It may have occurred The spread in Europe from Southeast Asia, where the pathogen was in a different species. Then, when it spread to a species that it did not encounter naturally in evolution, the pathogenicity was very basic,” explains Vlastimil Pechina, Head of the Department of the Selzna Hora Protected Landscape Area.

“This is all a result of today’s world, where there is a lot of movement of people across continents, and that is causing species to move to places they wouldn’t normally go to. In some cases things are not going well.” He adds that this is already a common problem. Ash trees are completely gone.
“The extent of infection varies in the stands. We observe the most severe tree death in the northwest part in the Běstvina and Bousova region. Otherwise, even in the entire territory of the protected landscape area, we record attacking ash trees.”
This also applies to a national scale. There is no defense against the pathogen. The only option is to remove infected trees. The only solution is to cut. Ash trees of different ages are gradually disappearing from the terraces. We record it most in southern Moravia, where this tree is an essential part of the forests. Every year, we have to remove several thousand cubic meters of trees affected by the heat wave,” says Eva Yoklova, a spokeswoman for Lesser.
Conservationists believe that the ash trees will not disappear completely and that the trees will gradually find a way to protect themselves from the cold.
