Yes. ,,In recent years, the problem of drying up of elm plantations has been acute in St. Petersburg. The cause of the mass death of elms is the Dutch disease, or graphiosis of elms, which is spread by sapwood beetles. In elm plantings, Dutch disease and sapwood are spread in the form of foci – clusters of affected trees. The area of spread of graphiosis across the territory of St. Petersburg is increasing every year - the number of foci of the disease and their size are increasing, more and more elms are dying.
Southeast Asia is considered to be the birthplace of the pathogen of the Dutch disease, since resistant species of elm are known for this region. From there, the marsupial mushroom Ophiostoma elm got to Europe, presumably with baskets of elm twigs, in which Chinese workers hired to build defensive structures during the war transported things.
In Europe, elm disease first appeared in 1917-1919 in the Netherlands, which is why it became known as Dutch. In the 1930s, with loads of logs, the causative agent of Dutch disease was introduced to North America through the ports of the Atlantic and the Gulf of Mexico. This disease in the sixties of the twentieth century led to the death of a huge number of elms in the northeastern United States. In the 1960s, the re-import of wood from the United States to Europe caused the spread of a more aggressive strain of ophiostoma. Another outbreak of Dutch disease essentially destroyed the elm forests in the south of Great Britain in the 1970s and early 1980s. Europe has lost about 70% of its elm plantations.
In 1936, the Dutch disease reached the western regions of the USSR and southwest Asia. The infection spread through the European part of Russia from south to north. In 1967, the first pinnate-branched elm trees with signs of Dutch disease were discovered in the Volgograd region.
Elms appeared in the historical gardens of St. Petersburg in the first third of the XIX century. Two species were planted in the city – smooth elm (fig. 1, a) and rough elm (Fig. 1, b). In St. Petersburg, elm sapwood trees (carriers of graphiosis) were the first to appear - in 1995 they were discovered on elms in Pushkin. 7 years later, in 2002, the death of elms from Dutch disease began to be actively registered. In the park of the Forestry Engineering University, about 70% of elms died in the period from 1995 to 2014. Currently, old-age elms in the historical parks of St. Petersburg are massively dying (Summer Garden, Catherine Garden, Mikhailovsky Garden, Alexander Park, Tauride Garden, etc.). Dutch disease destroys trees in young elm plantings along streets in all districts of the city. In 2016, about 800 foci of Dutch disease were registered, and this is far from a complete picture.,,
