The Koigorodsky National Park (56.7 thousand hectares) was established on December 7, 2019. It is located on the border of the Komi Republic and the Kirov region. An annotated list of liverworts collected in the Koigorodsky National Park has been presented in the article for the first time. The list includes 38 species and one subspecies of 28 genera, 21 families, seven orders (Blasiales, Jungermanniales, Marchantiales, Metzgeriales, Pelliales, Porellales, Ptilidiales), and two classes (Marchantiopsida and Jungermanniopsida). For each species, the article provides data on structures associated with reproductuion, geographical locations, substrate and the species habitats. Three liverworts species listed in the Red Data Book of the Komi Republic such as Anastrophyllum michauxii, Lophozia ascendens, and Scapania apiculata have been found in the flora. Indicator species of old-growth forests such as Calypogeia suecica, Crossocalyx hellerianus, Riccardia latifrons, and Syzygiella autumnalis have been found. The rare epiphytic liverwort Frullania oakesiana has been discovered in the Komi Republic flora for the first time. 23 species that can potentially be found within the Koygorodsky National Park have been identified on the Tulashor site adjacent territory (the Nurgush Nature Reserve). At present, the taxonomic diversity of the studied flora is probably 62%. The floras of the Koigorodsky National Park and the Tulashor site are parts of a single flora covering a large old-growth spruce forests array and, accordingly, are similar in structure. Forest habitats and spruce forests are characterized by the highest taxonomic diversity: 33 or 87% and 27 or 71% species, respectively. Liverworts prefer to grow on rotting wood due to reduced competition from vascular plants. About 79 % of the identified species form reproductive structures. This indicates that growth conditions are favorable. The remote southwestern part of the national park is promising for further research. |
