Cosenza,Diogo Nepomuceno; Soares,Vicente Paulo; Leite,Helio Garcia; Gleriani,José Marinaldo; Amaral,Cibele Hummel do; Gripp Júnior,JoelAbstract: The objective of this work was to evaluate the application of airborne laser scanning (ALS) to a large-scale eucalyptus stand inventory by the method of individual trees, as well as to propose a new method to estimate tree diameter as a function of the height obtained from point clouds. The study was carried out in a forest area of 1,681 ha, consisting of eight eucalyptus stands with ages varying from...
EVALUATION OF NON-LINEAR TAPER EQUATIONS FOR PREDICTING THE DIAMETER OF EUCALYP...
Souza,Guilherme Silverio Aquino de; Cosenza,Diogo Nepomuceno; Araújo,Ana Carolina da Silva Cardoso; Pimenta,Lucas Veiga Ayres; Souza,Ramon BarretoABSTRACT This study aims to evaluate non-linear stem taper models for predicting the pre-commercial diameter of eucalyptus trees and to analyze the effect of genotype on stem taper. The treatments comprise three different genotypes of Eucalyptus sp. in a 3 × 3 m plantation spacing. Seventy sample trees aged 10 years were felled for each treatment. The outside bark diameter measurements were taken at 0.5 m; 1.0 ...
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...
APPLYING CLASSICAL FOREST REGULATION METHODS TO SMALLHOLDINGS WITH COOPERATIVE ...
Rode,Rafael; Leite,Helio Garcia; Binoti,Daniel Henrique Breda; Ribeiro,Carlos Antonio Álvares Soares; Souza,Agostinho Lopes; Cosenza,Diogo NepomucenoABSTRACT This study aims to assess the cooperative regulation process of forestry producers in comparison to the traditional individual regulation of properties. Twenty (20) forest properties are studied as examples of the development of three forest regulation scenarios: 1) individual regulation, 2) group regulation, and 3) cooperative regulation. The Net Present Value (NPV) of each of the scenarios is optimiz...
