Moss occurrences of the Great Vasyugan Bog system

The dataset contains information on moss occurrences in the territory of the Great Vasyugan Bog and its periphery (West Siberia). The dataset summarizes data of the author's bryological explorations of the territory; the surveys were conducted in 1998, 2005, and 2021. The dataset consists of 2028 occurrence records and includes both preserved specimens (308) and the ‘human observations’ of the author (1728). The ‘human observations’ are data of bryological relevés. The relevés were made during field explorations; all collected moss specimens were checked under the microscope and registered in Data Base. Only some of the checked specimens were stored into herbarium; preference was given to rare species, but for common species, it was down to notes. All the records are georeferenced. A total of 132 moss species belonging to 68 genera and 26 families are reported herein to occur in the territory.
