Abstract
The bryoflora of Ryazhkov Island (408 ha) has been supplemented by 9 new moss species (Anomodon viticulosus, Dicranum leioneuron, D. septentrionale, Drepanocladus polygamus, Fissidens adianthoides, Pseudoleskeella papillosa, Scorpidium cossonii, Sphagnum fimbriatum, S. subfulvum), the first of which is included in the Red Data Book of Murmansk Region [2025]. The number of species reached 148 (53 % of the reserve's bryoflora, 31 % of Murmansk Region). Anomodon viticulosus, Fissidens adianthoides, and Scorpidium cossonii are confined to rocky calcite veins and groundwater discharge sites. Currently, Ryazhkov is the most comprehensively studied small White Sea island (< 500 ha). Protection of rocky and wetland habitats is recommended during the development of tourist trails and scientific base infrastructure.
