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.
