The history of studying alien mycobiota in Russia goes back two centuries, but there are still no annotated lists of species even for the most well-studied regions. For a number of regions, the results of the study of individual model trophic groups are summarized. It has been shown that the number of alien fungal species is growing exponentially. The increase in the number of alien fungal species positively correlates with the richness of species composition of introduced tree species, the success of which is due to climate warming.

In urban agglomerations in the Arctic and Subarctic, botanical gardens and parks with successfully introduced tree and shrub species are characterized by a specific mycobiota, in which the role of zonally and regionally alien species and species complexes is significant. Our first results indicate that with increasing climate severity from the Murmansk region towards Taimyr, the number of alien species of fungi is decreasing. The vast majority of alien species have been identified exclusively in populated areas. No dangerous invasions of plant pathogens have been identified at high latitudes.

A brief overview of the work of the II International Conference «Problems and Prospects of Sustainable Development of the Soil Cover of Mountain and Plain Territories» and the III International Scientific School «Monitoring, Protection and Restoration of Soil Ecosystems in Conditions of Anthropogenic Pressure», held in Gelendzhik on June 4–9, 2024 on the basis of a branch of the Southern Federal University is presented. The main directions of work of the Conference and School are given, as well as the topics of the presented reports.
