They play a very significant role in maintaining the ecological balance of environment and have the potential to be a beneficial natural resource to humans but due to their minute size and difficult identification, they are not much focused for scientific studies and have not been utilized in at most capacity. The hilly terrain of Uttarakhand with dense forest and shade covered forest floors is very suitable for luxuriant growth of Bryophytes. They are bioindicators and bioremediatory in addition to being pharmaceutically and industrially important. With the rapid climate change, urbanization and industrialization, it is important to conserve and manage these species which might become extinct even prior to our acknowledgment. Present study was a contribution towards the taxonomic description of bryoflora of Ramgarh in Nainital district. In the investigation, total of 28 species were reported, out of which four were liverworts, one was hornwort and 23 mosses. Out of 23 mosses, 12 were acrocarpous and 11 were pleurocarpous in habit. Liverwort species belong to four genera of three families and two orders whereas mosses belonged to 23 genera, of 15 families and six orders. Out of the six orders dealt in present work, Hypnales was largest consisting of eight families, 11 genera and 11 species followed by Bryales, Dicranales, and Marchantiales consisting of two families each. In mosses, Pottiaceae was dominant with 5 genera followed by Thudiaceae with three genera, Amblystegiaceae and Polytrichaceae with two genera each. In liverworts Aytoniaceae was dominant consisting of two genera incuding two families. Majority of the taxa were terricolous in habit.EnglishThesis
