Abstract

The inventory carried out in the floodplain area of the Guamá River, on the lands of the Porto da Ceasa community presented 2,014 individuals, containing 56 species and 44 genera for 27 families. The family Araceae presented the highest Importance Value 91.70861236% with 1. 024 individuals and the highest Basal Area, 35128.306 cm, with Relative Dominance of 32.969784%; the family Mimosaceae presented the highest diversity, with seven species; the families Mimosaceae and Arecaceae presented equal highest values of Relative Frequency, 8.7719298%; at the species level Montrichardia arborescens presented the highest Importance Value (89.528161 %), the highest Relative Frequency (5.7142857) and the highest Total Basal Area (78720.68 cm) with Relative Dominance of 32.969784%. The trees belonging to the DBH class between O and 20 cm represented 95.183714% of the individuals. It was verified that the stem height between O and 8 meters represented 1,950 individuals and that the cumulative curve of the appearance of new species reached the sampling sufficiency of identified species. Species such as Theobroma cacao, Spondias mombin and Euterpe oleracea are part of the diet of the residents of the area, whose surpluses are marketed as an alternative income for the community.
