Among all groups alien fungi are the least conspicuous. These are most often so small that they are not visible to the naked eye. Despite their small size, alien fungi can have serious impacts to native plants and animals. When they infect trees, they can cause changes on roots, trunks, bark, cause drying of shoots or canker scars. As they are often species-specific, they can cause die-off of single tree species, which can result in long-term changes in ecosystems. When fungi infect economically important tree species, monetary loss can be significant. Because of this, several alien fungi are subject to strict phytosanitary measures in the whole European Union.
Below, you can see some of the fungi species, which are subject to management in Slovenia. Some are already widespread, some only locally present and some still absent with a likelihood of entry to Slovenia.
Please note, that the species descriptions, which are linking on from the thumbnails have not been translated, but we will soon provide links to the English descriptions. The Slovenian descriptions are collected from several sources, provided at the bottom of each description.
Observation list: Includes selected alien species, which are relatively widespread in Slovenia and recognised as invasive. Reporting these species is important for monitoring their spread, planning of management measures and awareness raising.
Alert list: Includes potentially invasive alien species, which are likely to arrive in or spread to Slovenia in the near future. Some of the alert list species are already present in Slovenia and locally forming larger populations, however with adequate measures, their further spread could still be prevented.
