The aim of this study was to develop volumetric equations for tachi-branco trees (Tachigali vulgaris L. G. Silva & H. C. Lima), by assessing the effect initial planting spacing in volume estimates, as well developing an equation estimate equivalent diameter (deq). Data are from experiment located north Pará. conducted with randomized blocks design, being three six treatments each. most used...

Cork is a versatile natural material. It can be used as an insulator in construction, among many other applications. For good forest management of cork oaks, owners need to calculate the volume periodically. This will allow them choose right time harvest cork. The traditional method laborious and consuming. present work aims automate process calculating trunk area oak from which extracted. Thro...
