The "Ilha de Germoplasma", an island located in the Tucuruí Reservoir, Pará state, Brazil, is used to keep some of the species rescued from areas which were flooded by the Tocantins River, after the construction of the dam, in 1984. In this work we studied the bryophytes of this island, where identified 12 species of mosses and 13 liverworts were found. This result reflects the low diversity of bryophytes species occurring at the island, in comparison to other areas already studied in Pará State.
