Prognosis of the diameter structure of an Araucaria Forest with ratio movement and transition matrix PFB - Pesquisa Florestal Brasileira
Stepka, Thiago Floriani; Dias, Andrea Nogueira; Figueiredo Filho, Afonso; Machado, Sebastião do Amaral; Sawczuk, Alex Roberto.
The projection of the diameter structure of an Araucaria Forest was performed by the methods ratio movement and transition matrix. Data were collected in 25 permanent plots with an area of one hectare each. These plots were installed and measured in 2002 and re-measured in 2005 and 2008 in an Araucaria forest fragment with 1273 ha located in Irati National Forest, Parana State. All trees with diameter at breast height (dbh) greater than or equal to 10 cm were measured and identified. Based on data from 2002 and 2005 measurements, it was made to the projection of the diameter structure for 2008 using the methods ratio movement and transition matrix, comparing these projections with observed data from remeasurement of 2008 was projected. Regarding mortality...

CLASSIFICATION OF PRODUCTIVE CAPACITY OF Pinus taeda L. PLANTATIONS IN THE WESTERN REGION OF THE STATE OF SANTA CATARINA, BRAZIL Sci. Agrar.Paran. / SAP
Santos, Ricardo Murilo Malheiros dos; Arce, Julio Eduardo; Dias, Andrea Nogueira; Martarello, Vlademir; Roveda, Marcelo.
ABSTRACT - This study aimed to test different statistical models to adjust site index curves and apply models of identity tests in comparing the mean curves of dominant height in Pinus taeda to two regions of the West of the State of Santa Catarina. Data dominant height were obtained from permanent plots,with 600 m² size, distributed randomly. Selecting the best adjusted statistical model was made through the following adjustment and accuracy of statistics: determination coefficient (R²adj), standard error of estimate (Syx) in absolute and relative terms and graphic distribution of waste. The test Regazzi (2003) was applied to analyze the possibility of using a single model of the dominant height for the two regions. The Prodan model was chosen for...
