Study of factors affecting the diversity of moss at Ton Tok Waterfall The purpose of the study
was to study the optimal conditions of moss growth on the temperature and relative humidity of
the air, as well as the characteristics of ground cover and canopy plants on moss diversity
during October 2025-January 2025. The results of the study showed that there were 2 types of moss, 9 types of moss and dwelling mosses, with similar growth conditions of temperature and relative humidity. The average temperature is 27.65°C - 28.3°C, the average relative humidity is 66%- 68%, and the density of vegetation cover is similar. The average value of canopy plants is 93.75%-100%, and the average of ground cover plants is 43.75%-18.75%, which results in the presence and diversity of moss in the area around Ton Tok Waterfall.
