• forest management
• harvest in management areas
• cost
• vines cutting.

this survey was conducted in the tapaj車s national forest, in the state of par芍, brazil evaluating the cost and income of four different methods of cutting vines in the course of forest management, looking to log wood production. each method was conducted in an area of 96 ha by cutting the vines (1) around all commercial and potentially commercial trees (method m1), (2) only in the area of commercial and potentially commercial tree occurrence (method m2), (3) around al commercial and potentially commercial trees and toward fall (method m3), and (4) only around those commercial trees chosen for the first harvest (method m4). in all variables analyzed, the methods differed statistically.method m4 which showed the lowest cost (6.35 u.s. $), may be considered the best. in this method, the vine population was partially preserved, which is important ecologically.
