Bryophyte cover of an area is a clear indication of the health of the ecosystem. These archegoniates constitute 5.62% of total plants of India. Luxuriant forests, varied topography and suitable climatic conditions made Kumaun Himalaya rich in bryophyte diversity. Nature’s furies and human interference have, however, started posing a toll on the diversity of the region. Hence, taxonomy and documentation of its flora is essential for conservation and management of the biodiversity. Present study was an attempt to survey, collect and taxonomically describe the bryoflora of Berinag region including the villages and forest of Berinag. In the investigation, total of 33 species were reported, out of which eight were liverworts and 25 were mosses. Out of 25 mosses, 15 mosses were acrocarpous and 10 mosses were pleurocarpous in habit. Liverworts species belonged to six genera of five families and two orders whereas mosses belonged to 24 genera of 17 families and eight orders. Out of the 10 orders dealt in the present work, Hypnales was the largest consisting of seven families, nine genera and nine species followed by Dicranales and Marchantiales both consisting of three families, five and four genera respectively. In mosses, Bryaceae was the dominant family consisting of three genera and four species followed by Calymperaceae, Leucobryaceae, Anomodontaceae, Leskeaceae and Polytrichaceae. In liverworts, Aytoniaceae was found dominant. Marchantia, Frullania and Bryum were the dominant genera of the region. Majority of the taxa were terricolous in habitat.ennullThesis
