Describing the Structure and Relationship of Height and Diameter in an Old Unma...
Abreu Neto,Raul de; Abreu,Marcel Carvalho; Soares,Alvaro Augusto Vieira; Monte,Marco Antonio; Araújo,Emanuel José Gomes de; Curto,Rafaella de AngeliAbstract The aim of this study was to model the height and diameter distributions and the height-diameter relationship in an old unmanaged Eucalyptus stand in southeastern Brazil. The diameter at 1.30 m above soil (DBH) and total height (H) of all 469 trees in the stand were measured. For the DBH-H modeling, besides testing various traditional linear and nonlinear models, the inclusion of diameter class as rand...
WOOD COLORIMETRY FOR THE CHARACTERIZATION OF AMAZONIAN TREE SPECIES: A SUBSIDY ...
Sousa,Wilza Carla Santos e; Barbosa,Lucas de Jesus; Soares,Alvaro Augusto Vieira; Goulart,Selma Lopes; Protásio,Thiago de PaulaABSTRACT The wood of different species may present macroscopic similarities, which hinders a reliable differentiation between the specie. This can be a problem, especially in the tropics, given the high species diversity in this region. To overcome this problem of wood identification, colorimetric criteria can be applied, aiming at a better and more objective classification, as opposed to the traditional anatom...
Dominant Height Growth in Tectona grandis Plantations in Mato Grosso, Brazil
Vendruscolo,Diogo Guido Streck; Drescher,Ronaldo; Carvalho,Samuel de Pádua Chaves e; Medeiros,Reginaldo Antonio; Môra,RômuloABSTRACT Tectona grandis (teak) plantations have gained increased interest in recent decades in Brazil, bringing about the need for acquiring information regarding the growth and productive potential. The present work aims to evaluate the growth of dominant height in teak at various locations in the state of Mato Grosso, midwest Brazil. For this purpose, six stands were evaluated in distinct municipalities and ...
SITE CLASSIFICATION FOR EUCALYPT STANDS USING ARTIFICIAL NEURAL NETWORK BASED O...
Cosenza,Diogo Nepomuceno; Soares,Alvaro Augusto Vieira; Alcântara,Aline Edwiges Mazon de; Silva,Antonilmar Araujo Lopes da; Rode,RafaelABSTRACT Several methods have been proposed to perform site classification for timber production. However, there is frequent need to assess site productive capacity before forest establishment. This has motivated the application of Artificial Neural Networks (ANN) for site classification. Hereby, the traditional guide curve (GC) procedure was compared to the ANN with no stand measures as input. In addition, dif...
INFLUENCE OF ECOLOGICAL GROUP COMPOSITION, PLANTATION SPACING AND ARRANGEMENT I...
Soares,Alvaro Augusto Vieira; Botelho,Soraya Alvarenga; Davide,Antônio Cláudio; Faria,José Márcio RochaABSTRACT This work aimed to assess the effect of spacing, arrangement and ecological group composition of planted seedlings on the restoration process of artificial reservoir shores in southeastern Brazil. The assessments were performed 12 years after the settlement of the experiment in which five mixed stand models were tested. First, a general evaluation of the stand was performed when we surveyed the oversto...
