Criteria to be considered to achieve a sustainable second cycle in Amazon Forest PFB - Pesquisa Florestal Brasileira
Braz, Evaldo Muñoz; Mattos, Patricia Povoa; Thaines, Fabio; de Madron, Luc Durrieu; Garrastazu, Marilice Cordeiro; Canetti, Aline; d’Oliveira, Marcus Vinício Neves.
Remnant forest structure and increment by diameter class play a decisive role in the recovery volume for the next cutting cycle. Tree species in the Amazon Forest do not present a defined pattern of diameter structure, which is discussed here using Cedrela odorata L. as a case study The aim of this study was to identify, by simulation, recovery from logging in a real situation at three timber production sites, and the alternatives that are available to ensure commercial timber volume to a second cut cycle in the Brazilian Amazon. The study is concerned regarding the diametric classes of productive trees to the next cycle, the comparison demonstrates that one of the strategies recovers stock volume more quickly than expected in the cut cycle defined by...

Growth dynamics of tree species in a remnant of Araucaria Forest PFB - Pesquisa Florestal Brasileira
Canetti, Aline; Ruy, Camila Castilla; Mattos, Patricia Povoa de; Braz, Evaldo Muñoz.
Studies that address the appropriate use of forest resources are essential for the management and conservation of forest remnants, such as the Araucaria Forest. Considering the importance to improve the knowledge of the tree species growth in subtropical regions, the present study aimed to assess the intra-annual diameter growth of tree species in Colombo County, Paraná State, Brazil. In November 2009 dendrometer bands were installed in adult trees (15 to 25 trees) of 9 species among the most frequent in the studied Araucaria Forest remnant. The increment in diameter were measured monthly until June 2011. Ocotea bicolor grew faster and more constant than the other species. This may be due to lower coverage of the trees canopies, making easier to O. bicolor...
