Popis:	The objective of the present study was to analyze the ecological aspects of Heteropsis spp. Kunth (titica vine) in an area maintained under forest management conditions. The study was carried out in the Tapajós National Forest, Pará state, Brazil, at Annual Production Unit 11. For the inventory of trees hosting titica vine, 206.25 hectares were covered. The parameters recorded were diameter at breast height - DBH (1.30 m above the soil), total height (Ht), regional name and geographical coordinates. The mature and immature aerial roots of titica vine were counted and the mass of mature roots with and without bark was collected and measured. The density of the host trees in different class centers of DBH and Ht was related. The ratio between the DBH and Ht of the host trees and the mass of mature root with bark of the titica vine was calculated. Spatial distribution was based on Ripley’s K function. A total of 337 trees were inventoried as hosts, with average density of 1.65 trees.ha-1, distributed in 88 species. Trees with DBH
