Diversidade de bromeliáceas epífitas na área de Prote？？o Ambiental Ilha do Combu, Belém, Pará, Brasil

information about diversity at the species level offers data for sustainable development and biological conservation. in this context, studies about bromeliaceae are noteworthy, especially because this group is ecologically important and poorly known in the north region of brazil. in this study, two grids (100 m x 100 m) were delineated in a floodplain forest in the environmental protection area of combu island, belém, pará, brazil. the grids were subdivided into eight grids of 50 m x 50 m, and all species and individuals of epiphytic bromeliaceae were recorded and quantified. the diversity was calculated using the shannon-wiener index. a total of 1,339 individuals, belonging to eight species and four genera were recorded. tillandsia and aechmea presented the greatest richness. the diversity of species was h= 1.10, presenting sharp dominance of many individuals of few species.
