Abstract: We investigated the diversity of epilithic mosses in Sejila Mountain of Nyingchi City, Tibet, and evaluated the biomass, soil formation capacity, and water holding capacity of three dominant species. The results showed that there were 8 families, 12 genera and 16 species of epilithic mosses. Hypnaceae, Thuidiaceae, and Dicranaceae were the dominant families, while Ptilium crista-castrensis, Dicranum fuscescens, and Actinothuidium hookeri were the dominant species. Biomass of dominant species of epilithic mosses was 110.7-763.6 g·m-2, with a soil formation capacity of 234.9-9063.3 g·m-2, a maximum water holding capacity of 2164.5-8514.5 g·m-2, a maximum water holding rate of 169%-400%, a natural water holding capacity of 1984.74-6764.5 g·m-2, and a natural water holding rate of 95%-318%. Therefore, the epilithic mosses in Sejila Mountain play an important role in soil formation and water holding, which is of great significance for soil erosion control and also for soil and water conservation.
