Abstract– Bryophytes are the second largest group of green plants and are widely spread in almost all climatic conditions. Bryophytes are good indicators of weather change and pollution. Diversity patterns and species composition of bryophytes can help us in understanding and planning natural conservation strategies. The study was conducted to understand the seasonal variation in the species composition of bryophytes in Madhepura District, Bihar. A total of eleven species representing seven families were recorded during the post-monsoon (PM) season and fifteen species representing eight families were recorded during the post-monsoon-to-winter (PwM) season in the Madhepura District.
The values of Shannon- Wiener index and Simpson’s index suggests that the diversity of bryophytes were almost similar during both the seasons. Margalef’s index during PW season indicates that the species richness during the season is little disturbed, but is semi-disturbed during the PwMseason .Pielou’s Evenness index indicates that species were more homogenously distributed during PW season than during PwM season
