A rare "big sponge cake" appeared in the Bohemian Forest after a hundred years



As the National Park Authority recalled, the last time experts recorded a bohemian forest in the Forest Mountains between 1905 and 1907. The presence of a bohemian forest was also highly appreciated for its reduced population in the Beskydy Mountains.

"The first finding in the Bohemian Forest was definitely accidental when foresters discovered it last year in the Bear Trail area in the Stožec area after being thrown out of a bug trap. Even then, my colleagues and entomologists told me that its population would not only be a few pieces, but it would certainly be higher, because the chance of accidentally throwing a unique specimen into a trap is about as large as the winner of the Jackpot lottery, "described Vladimir Dvorak of the National Park Directorate Sumava.

This year's follow-up subsequently confirmed the occurrence of crustaceans in the area of ​​Hučina and on the Třístoličníkua massif, where they discovered dozens of pieces, believing it to be not a definitive number, and will reveal an even more widespread occurrence of beetles in further investigations.

Experts describe it as a forest expert, appearing only in the area with standing torso of dry firs or spruce of large size, on which fungi – wood fungi occur.

"Moreover, those torso must be dead and illuminated for at least 10 years. So, where more trees die at the same time," said the park's management, why the forest crown has favorable conditions.

"The fact that we discovered it in the Triculicum area is related to the death of the top bottom of the tree due to the feeding of the dental temple and the subsequent & # 39; ripping of the tree upright. It has been confirmed to be a forest in all forms," ​​Dvorak said.

Another species discovered is the beetle deer. So far, it has only been described in Beskydy or Jeseníky or in the Bohemian Forest. Tree beetle inhabits rotten fir trees, spruce and, exceptionally, beech trees.

"A deer bug needs enough dead wood for its life, which is widespread and has so-called brown rot. In this tree, it develops from larvae to adults. Tribes leave adult bugs and do not migrate long distances, ”said Pavla Čížková of the Šumava National Park Administration.

Entomologists have also found other endangered species in non-intervention areas of the Forest, where the tree remains decaying. These include the critically endangered cockroach, the species Ampedus auripes and Danosoma fasciata.

"Thanks to such discoveries, it is possible to say that the territory of the Šumava National Park acts as Noah's Ark. The aforementioned beetle species had to survive surreptitiously somewhere and waited for the opportunity to expand. parts of protected landscape areas. And they are defined by a large number of dead trees, "said Pavel Hubený, director of the Šumava National Park Authority, one of the senses of non-intervention zones.
