Briófitas da área urbana de Belém, Pará, Brasil. I-musgos, II-hepáticas.

Abstract

A survey of bryophytes in the urban area of Belém is being conducted. It started in June 1992. It is based on the collection of material from public places, such as squares, parks, streets, backyards, etc., and forest reserves (Mocambo and Utinga), besides the analysis of material from the herbarium of MPEG. The available data are not sufficient to draw definite conclusions, since the material is still being collected. The results of this work can provide data for the use of bryophytes in environmental biomonitoring, using the collection of material in areas of great anthropological interference, in contrast to the material found in areas away from the urban center (forest reserves), where human influence is practically nonexistent. For this, however, prior knowledge of the species that occur in both environments is necessary, thus leading to a broad knowledge of the bryophytic flora of Belém.
