Bryophytes, Rondônia, Environment, Biodiversity.

The bryophytes are considered the second largest group of terrestrial plants on the planet represented by the lineages Bryophyta (mosses), Marchantiophita (liverworts) and Anthocerophyta (anthocerophytes). These plants are present in different substrates such as soils, rocks, trunks, tree branches, decomposing wood, contributing a significant proportion of biomass and moisture to the growth of vascular plants in these ecosystems, participating in the carbon and nitrogen cycle and also as environmental bioindicators. The main objective of this research is to taxonomically identify the species of bryophytes collected from the Raimundo Paraguassu de Oliveira Municipal Natural Park in Porto Velho, contributing to the brioflora of Rondônia and its conservation in the state. The collections will be made by the walking method with random collections on different substrates for later identification at the João Geraldo Kuhlmann Herbarium Rondoniense and production of exsiccata. This research is expected to survey the bryophyte species present in the Park, contributing to the knowledge of existing bryophytes in conservation units in the State of Rondonia, raising the awareness of researchers and communities in Rondonia about the participation of brioflora in the ecosystem balance and maintenance of local biodiversity.
