Thank you for your request. This is heavy infestation of an ash tree by Hylesinus varius (= fraxini). More about this pest here: https://www.forestpests.eu/pest/ash-bark-beetle. Wish best regards MZ.
Thank you very much for your inquiry. Upon observation of the tree, there are signs of the presence of some species of Cerambycidae - longhorn beetles. However, from the picture provided, it is not possible to determine the exact species of the beetles. It is important to note that these beetles typically only play a minor role in tree decline, as many of them are strongly secondary pests that attack and inhabit weakened or damaged trees. Therefore, in this case, it is not possible to determine the exact reason for the mortality of the tree from the picture alone. Thank you very much and have a nice day! MZ
