SUMMARY:

Studies on the importance of epiphytes for biodiversity in tropical and temperate forests are recent. Epiphytes correspond to about 10% of vascular plants recorded for Brazil. Until then, only 16 published works on epiphytic synusia were registered for the Brazilian Amazon, mostly punctual studies, addressing only one family. The canopy of a tropical forest is considered “the last biotic frontier”, however, the difficulties in accessing this region is one of the factors that contribute to the lack of volume and breadth of studies. In the canopy of the Amazon phytogeographic domain, the Brazil nut tree (Bertholletia excelsa Bonpl., Lecythidaceae) is a tree species that stands out, and the seed of the species has a high economic value, constituting the second largest non-timber forest product in the North of the state. Brazil. In this context, the objective was to carry out a floristic survey of vascular epiphytes on chestnut trees in the locality of Carará, one of the most expressive chestnut groves in the Ipaú-Anilzinho Extractive Reserve, district of Baião, Pará. Thirty chestnut trees were randomly selected, with DBH >80 cm and more than 30 meters in height, and another 30 phorophytes with DBH 35-80 cm and height < 30 m, in order to better estimate the floristics and epiphytic diversity present in chestnut trees. Seven families, 20 genera and 27 species were counted on these 60 phorophytic individuals. Orchidaceae was the most representative family, with nine genera and 14 species, followed by Polypodiaceae, with five genera and six species, and Bromeliaceae, with two genera and three species. The ecological zone that presented the most species was the inner canopy, with 22 species. Among the 19 phorophytic species surveyed, Bertholletia excelsa was the species that most harbored epiphytes, hosting 18 of the 27 recorded species. The data obtained in the present study corroborate the size and age of the phorophyte as relevant in the abundance of epiphytes on the phorophytes.
