Currently, the study of the mosses (Bryophyta) of the Northeast Paraense is being developed. It has 5 Microregions, among them the Microregion of Salgado where the town of Salinópolis is located, on the shores of the Atlantic Ocean and presents the most beautiful beaches of Pará. It has a great variety of ecosystems such as restinga, mangrove, dryland forest, igapó forest and capoeira, which are being affected by intense anthropic use, as a consequence of the indiscriminate use of its lands for tourism and construction of houses for vacationers. This work aims to continue the inventory of moss species that occur in the different ecosystems of the northeastern region of Pará State. In this stage of the work, the samples of mosses collected during excursions to Salinópolis were studied. The material was collected randomly and identified according to the usual methodology. The results found in 140 moss samples present 21 species, distributed in 7 genera and 6 families. Sematophyllaceae, Leucobryaceae and Ca1ymperaceae, stood out both in species diversity and number of occurrences. Sematophyllum subsimplex (Hedw.) Mitt, Calymperes erosum C.Müll., Calymperespalisotii Schwaegr. and Oetoblepharum albidum Hedw. varo albidum are the most abundant species. The vast majority are corticolous species and occur in the dryland forest. Species have been observed on other substrate types, except on leaves. The interference of man in this area results in the loss of moss species, which is confirmed by comparing the results found with those from other municipalities in the Northeast Paraense.
