Brazil has the largest biodiversity of fauna and flora of the world. This brings a great potential and challenges for forest management in the country. In this study the structure of 84 hectares of natural forest was analyzed, in the Rio Capim Farm that belongs to the forestry company CIKEL Brasil Verde Ltd. It was registered a number of 1435 trees with dbh = 45 cm, distributed in 65 species, 54 genera and 22 families. The most important species were: Eschweilera sp. with a Coverage Index Value (CIV) of 32.62, followed by Manilkara amazonica (CIV = 19.36). The species Hymenaea courbaril presented the biggest volume (5,115 m3.ha-1). The species Manilkara huberi, Goupia glabra, and Lecythis usitata also had high CIVs and volumes. The species Brosimum parinarioides, Protium puncticulatum, Anadenanthera colubrina, and Lecythis lurida complete the list of the most important species in the studied area. Most of the species are traded in the domestic market, but part of these species reaches the international market. Other species have great importance for producing non-timber forest products such as medicines for phytotherapy, fibers, and fruits. The recommendations presented here can be applied in other tropical forests with similar structure of the forest studied in this work.
