Wood volume model for Cerrado species from Formosa, Goias State, Brazil
dos Santos, Andreia Taborda; Domene, Vitor Dressano; Mattos, Patrícia Póvoa de; Braz, Evaldo Muñoz; Canetti, Aline; Nakajima, Nelson YoshihiroThis study aimed to develop models for estimating wood volume of individual trees for nine Cerrado species of Formosa, State of Goias, Brazil. Data were collected from 12 to 15 trees of nine species, representing the diametric classes amplitude of each species in the studying area. Trees were logged and measured and the volume was calculated by Smalian method. Seven mathematical models were tested to estimate t...
Horizontal structure analysis by Kernel density as basis to forest management i...
Oliveira, Mariana Ferraz; Mattos, Patricia Povoa de; Garrastazu, Marilice Cordeiro; Braz, Evaldo Muñoz; Figueiredo Filho, Afonso; Rosot, Nelson CarlosThe present work aimed to characterize the horizontal structure of an area of primary Amazonian Forest and the spatial distribution of the species Goupia glabra (Aubl.), Qualea spp. and Dipteryx odorata (Aubl.) Willd. through the analysis of the Kernel density, aiming to support the planning of forest management. The study area is located in Santa Carmem, microregion of Sinop, state of Mato Grosso (1,024 ha), w...
Estimativa do peso de madeira seca de Pinus taeda L. por ocasiao do primeiro de...
Rosot, Nelson CarlosO presente estudo, conduzido em um povoamento de Pinus taeda da MANASA-Madeireira Nacional S/A sediada no município de Guarapuava, estado do Paraná, teve como principal objetivo estudar e selecionar um modelo de regressão para estimar o peso de madeira seca comercial de Pinus taeda em função de parâmetros dendrométricos de fácil obtenção no campo. Para este trabalho foram utilizadas 158 árvores de Pinus taeda d...
Estimating wood volume in plantation of Ocotea porosa
Santos, Andreia Taborda dos; Mattos, Patricia Povoa de; Braz, Evaldo Muñoz; Rosot, Nelson CarlosTo know the volume of wood from a forest is extremely important. Volume equations for species from the Araucaria Forest are restricted almost exclusively to plantations of araucaria. Equations for Ocotea porosa (Nees & Mart.) Barroso plantations are inexistent. The present work aims to develop equation for individual tree volume and hypsometric relation from an Ocotea porosa, established in the region of Ri...

Foram utilizadas imagens dos sensores JERS1-SAR e LANDSAT-5 TM, am...
Rehabilitation practices in a burned Araucaria Forest patch: partial results
Rosot, Nelson Carlos; Dlugosz, Fernando Luís; Rosot, Maria Augusta Doetzer; Kurasz, Gilberto; Oliveira, Yeda Maria Malheiros de OliveiraThis study describes the initial measures taken to reconstitute the forest cover in a burned area of Araucaria Forest by means of planting seeds and seedlings of Araucaria angustifolia (parana pine) and Ocotea porosa (imbuia). The study area is located at the Experimental Station of Caçador, in Caçador, State of Santa Catarina, Brazil. Species were systematically arranged in lines and rows over the experimental...
Structure and dynamics in remnants of Araucaria Forest in Southern Brazilian pl...
Lingner, Débora Vanessa; Oliveira, Yeda Maria Malheiros de; Rosot, Nelson Carlos; Dlugosz, Fernando LuísThe present work aimed the characterization of the structure and dynamics of a forest patch belongingto the Ombrophylous Mixed Forest (FOM). Data from 10 permanent plots (25 x 100 m) representing the forestsubtype “predominance of Araucaria”, located at the Forest Reserve Embrapa-Epagri, in Caçador, State of Santa Catarina, were analyzed. Each tree whose girth at breast height (GBH) was equal or larger than 60 ...
Conventional aerial sketchmapping and digital aerial sketchmapping development ...
Dlugosz, Fernando Luís; Rosot, Nelson Carlos; Doetzer Rosot, Maria Augusta; Malheiros de Oliveira, Yeda Maria; Cordeiro Garrastazu, MariliceThis paper presents an approach to the technique of aerial sketchmapping in respect to its characteristics, applications and potential for use in Brazil, mainly to monitor changes in forest cover in Paraná state. The method consists of observation and annotation of features or phenomena from overflights in the area of interest flying at low altitudes along a predetermined route. It also presents the advantages ...
