Accuracy of two optical dendrometers for non destructive determination of woody biomass
Provedor de dados: 190
Autores: Nicoletti, Marcos Felipe; Batista, João Luis Ferreira; Carvalho, Samuel de Pádua Chaves; Castro, Tito Nunes de.
The objective of this study was to improve existing methods for determination of stem biomass in a non-destructive way, and verify the influence that laser dendrometers have on the prediction by existing empirical models in forest environment on the individual trees. This study was developed in Itatinga, SP, Brazil, in three plots of a Eucalyptus grandis plantation, totalizing 175 trees. The stem diameter of standing trees were measured with two dendrometers, Criterion and RC3H, along the stem up to 8 meters height. After the volume evaluation of standing trees they were felled and the diameter obtained with a caliper and a tape in the same positions in which the non-destructive measures were taken. Wood disks were removed and dried for determination of...

Description stem profile of trees through the taper functions
Provedor de dados: 22
Autores: Nicoletti, Marcos Felipe; Machado, Sebastião do Amaral; Carvalho, Samuel de Padua Chaves e; Figueiredo Filho, Afonso; Sanquetta, Carlos Roberto.
The objective of this study was to summarize information about the use of modeling the stem profile of trees through taper functions. It is known that some factors influence the growth of trees and consequently the stem profile. Then, the taper functions are responsible to study the stem profile and its variations that affect directly in forest planning. Thus, the modeling is a tool able to describe the stem profile and conduct the forest production for the different business. Aiming to improve the estimates of forest inventory, the improvement of statistic technical of modeling in the country already provide considerable results. Examples are mixed models and multivariate modeling innovate in this segment. These approaches have been used to improve the...
