Red List of Estonian lichens: revision in 2019

In August 2019, the Nordic Lichen Society held its bi-annual meeting and excursion in south-western Estonia. The most remarkable findings of lichenized and lichenicolous fungi are recorded herewith, including nine new species (of them two lichenicolous), and one new intraspecific taxon for the country. Full species lists are provided for two notable locations, sandstone outcrop at the river Pärnu and an oak woodland in the Naissoo Nature Reserve, for which no previous data were available, to illustrate the importance of collective survey effort. 2019. a augustis toimus Eestis korraline, iga kahe aasta järel korraldatav Põhjamaade Lihhenoloogide Ühingu kokkutulek ja ekskursioon. Artiklis anname ülevaate huvitavatest lihheniseerunud ja lihhenikoolsete liikide leidudest, sealhulgas üheksa (neist kahe lihhenikoolse) liigi esmaleiust Eestis ja ühe liigisisese taksoni esmaleiust. Lisaks esitatakse lihheniseerunud, lihhenikoolsete ja neile lähedaste seente täisnimekirjad, mis koostati kahe elupaiga – Tori Põrgu Maastikukaitseala liivakivipaljandi ning Naissoo Looduskaitseala koosseisu jääva Naissoo tammiku – kohta.

“…The aim of the Environmental Board procurement, announced in 2019, was to carry out regional assessment of the threat status of selected fungal species occurring in Estonia, except for lichenised fungi and polypores that have been recently evaluated. Species from the two last groups, assessed to belong to the threatened categories CR, EN, VU have been outlined by Lõhmus et al (2019) and Lõhmus et al (2018). Due the limited time the following…”

et al. 2019

In 2019 the conservation status of 214 fungal species in Estonia was assessed according to IUCN criteria and an IUCN category was assigned to each taxon. Altogether 94 species were categorized as threatened (CR, EN, VU), 42 least concern (LC), 60 near threatened (NT), three regionally extinct (RE) and six as data deficient (DD). Changes compared to the previous red list and threats to the species are discussed.

“…The threat status of Estonian lichens was evaluated in 1988 for the fi rst time; 40 species were included in the list of threatened lichens (Anonymous, 1993). Ten years later already 110 lichen species were included in Red Data Book (Randlane, 1998). In these two early Red Data Books of Estonia only macrolichens were evaluated using a conventional system of threat categories while the criteria for defi ning the categories were mainly intuitive-emotional (Lilleleht, 1998;Randlane et al, 2008).…”

A recent update in red-listing of Estonian lichens: threat status of 168 species was assessed for the first time

et al. 2022

The threat status of 168 lichenized species growing mostly on rocks or ground were assessed in 2022 for the first time in Estonia. The IUCN Red List system (categories and criteria) were used for that purpose. Most of the assessed taxa were microlichens (163), while five macrolichen species were also evaluated. Among the assessed species, 91 were assigned to the threat categories (Critically Endangered – CR, Endangered – EN and Vulnerable – VU), 17 species were assigned to the category Near Threatened (NT), and 41 species were assigned to the category Least Concerned (LC). Category Data Deficient (DD) was assigned for 17 species and the category Regionally Extinct (RE) for two species. Among the threat categories, 35 species were assigned to the category EN, 34 species to VU, and 22 species to CR. In general, most of the evaluated species (81%, 137 species) were growing on different types of rock, 16% (28 species) of species were growing on soil, mosses or plant debris, and three taxa were growing on other substrata. Most of the threatened epigeic and epilithic microlichens were recorded on alvar grasslands growing on ground, limestone pebbles and flatrock or erratic boulders. Er- ratic boulders in various forest types and calcareous cliffs in clint forest were also important habitats for threatened species. Moreover, different rock substrates of anthropogenic origin (walls, buildings and abandoned limestone quarries) performed as significant habitat type for epilithic species. Bush encroachment of open habitats, especially in semi-natural grasslands, serves as the main threat for epigeic and epilithic lichens.
