Size of plots and forms for forest inventory of tree species in central Amazon
Oliveira, Milena Marmentini de; Higuchi, Niro; Celes, Carlos Henrique Souza; Higuchi, Francisco GasparettoOne of the main tools to quantify and to qualify the forest potentials is the forest inventory. During its planning phase it is necessary to define the sampling intensity as well as the sizes and shapes of sample units to minimize data collection costs while increasing the precision of the forest inventory. This study aimed to test different sizes and shapes of sample units for different diameters at breast hei...

Tree climbing techniques and volume equations for Eschweilera (Matá-Matá), a hy...
Gimenez, Bruno Oliva; dos Santos, Leandro T.; Gebara, Jonas; Celes, Carlos Henrique Souza; Durgante, Flávia Machado; Lima, Adriano José NogueiraThe Eschweilera genus has great ecological and economic importance due to its wide abundance in the Amazon basin. One potential use for the Eschweilera genus is in forest management, where just a few trees are removed per hectare. In order to improve the forest management in the Amazon, this study assessed two critical issues: volume equations fitted for a single genus and the development of a non-destructive m...

Digital approach for measuring tree diameters in the Amazon forest
Celes, Carlos Henrique Souza; Araújo, Raquel Nazaré O. de; Emmert, Fabiano; Lima, Adriano José Nogueira; Campos, Moacir Alberto AssisButtresses and other natural structures modify the shape of stems in Amazonia and change the diameter at breast height (DBH) measured at 1.3 m at ground level. The lack of adequate measurement techniques affects negatively forest dynamics analyses and biomass estimating. The study evaluated an indirect method of measuring diameters in trees with DBH > 40 cm using principles of digital photogrammetry. The result...
