【 摘 要 】

The aim of this study was to characterize the forest structure with H. flexuosa in Rondônia State, as a first step in developing sustainable harvest and conservation guidelines for the species. Crown attributes, total height (m) and diameter at breast height ≥ 10 (cm) of trees and palms with H. flexuosa were evaluated in three permanent plots (100 m x 150 m each) randomized in 219 ha. A total of 22 botanical families hosted H. flexuosa. It was not observed any specific preference for the species standing up itself. Nevertheless it was frequently associated to Burseraceae, Leguminosae, Sapotaceae, Annonaceae, Chrysobalanaceae, Apocynaceae, Moraceae and Myristicaceae and species with thick bark like Schweilera coriacea, Protium sp. and Licania membranaceae. The species was less frequent with taller and broader trees and tended to develop in understory light condition. Trunks or branches were the main position for the attaching of H. flexuosa (90.83%) and a low frequency of other lianas was observed on the same host trees. These highlight the need to promote appropriate management practices for root harvesting and species conservation in order to maintain the species in open ombrophylus forest habitat.
