Morphometry of Araucaria angustifolia at different altitudes in Southern Brazil
Ricken, Pollyni; Hess, André Felipe; Mattos, Patrícia Póvoa de; Braz, Evaldo Muñoz; Nakajima, Nelson Yoshihiro; Hosokawa, Roberto TuyoshiMorphometric indices can be used to support the understanding of natural forest dynamics. The aim of this study was to describe and evaluate the morphometric and dendrometric characteristics of Araucaria angustifolia, to understanding of the structure of natural Araucaria Forest. The data were obtained in three counties of Santa Catarina State, considering different altitudes of occurrence of the species. We sa...
Application of generalized linear models to estimate height growth
Hess, André Felipe; Cianorschi, Lucas; Silvestre, Raul; Scariot, Rafael; Ricken, PollyniHeight growth analysis presents great importance in forestry, as it expresses site production capacity. Its use is associated with lower adjustment error models to generate estimates to inference with precision and reliability. The present study examined generalized linear models in predicting height growth of Pinus taeda L. depending on the age and diameter at 1.30 m height above ground level in stands in the ...
Basal area increment model of araucaria trees in uneven aged forest
Costa, Emanuel Arnoni; Finger, César Augusto Guimarães; Hess, André FelipeThe present study aimed to develop a mathematical model to describe annual periodic percentage increment in basal area of Araucaria angustifolia trees with data collected from increment cores extracted radially from the trunk at breast height of 109 trees distributed in a large diameter range. Dendrometric and morphometric attributes were tested by multiple linear regressions as independent variables and their ...
Araucaria angustifolia management by Liocourt quotient in rural field, Painel m...
Hess, André FelipeThe objective of this study was to calculate the ratio of Liocourt in natural forest with 50 hectares of Araucaria angustifolia. The diameter distribution behaved as expected for native forests, generating a distribution curve similar to an inverted-J. The forest showed 456 araucaria trees per hectare with diameter at breast hight (DBH) above 10 cm and basal area of 24.64 m² ha-1. The value of the Liocourt quot...
Araucaria angustifolia management proposal to use the quotient of Liocourt and ...
Hess, André Felipe; Calgarotto, Andressa Roberta; Pinheiro, Renato; Wanginiak, Thayana Cristina RebelloThe aim of this study was to calculate the ratio of Liocourt and evaluate the diameter distribution in natural forest with 84 hectares of Araucaria angustifolia serving as a parameter for its management in a farm of 176 hectares, located in White Stone Farm, Lages, Santa Catarina State, Brazil, to achieve the concept of balanced forest. Diameter distribution behaved as expected for native forests, generating a ...
Inter-relações no crescimento de Araucaria angustifólia (Bertol.) Kuntze em dif...
Hess, André FelipeConselho Nacional de Desenvolvimento Científico e Tecnológico; This study had as objective to compare the Araucaria angustifolia (Bertol.) Kuntze growth in three different places in Rio Grande do Sul state (Serra do Sudeste, Encosta Superior do Nordeste e Planalto Médio) in diameter, height and volume in function of age for each place and for the three places grouped, to establish the specie development behavio...
