| The strategic importance of forest resources, both at the national and global level, as well as the scarcity of reliable qualitative and quantitative information about Brazilian forests are among the motivations that led to the implementation of a new national forest inventory in Brazil (IFN-BR). Beyond traditional field survey through clustered sampling, the IFN-BR incorporates Landscape Sample Units (LSU) as a geospatial component of the inventory. Landscape indicators and indices are generated through the analysis of land use/land cover in the LSUs, which provide information about composition, morphology, mosaic patterns, adjacent habitat similarity, connectivity, fragmentation, and state of riparian zones. In the current study, we describe the... |

| In the present work the dendrochronological potential of six species of the Araucaria Forest is analyzed. The trunks of 20 trees were collected in Candoi, State of Parana, Brazil, from an area that belongs toELEJOR, Centrais Elétricas do Rio Jordão, for the following species: Araucaria angustifolia, Clethra scabra, Cedrela lilloi, Ocotea porosa, Podocarpus lambertii and Sebastiania commersoniana (3 to 6, from each species). The trunks were sawed, and at breast height a sample was taken from the center of the board, from bark to bark, crossing the pith, for macroscopic analysis. These samples were dried and polished, making possible the recognition and measurement of growth rings The historical climatic data series were provided by SIMEPAR, the State... |

| O objetivo deste trabalho foi avaliar diferentes comprimentos de transecto para determinação da necromassa florestal caída sobre o chão. Os dados são provenientes de transectos de 10 metros, medidos durante o teste de metodologia do Inventário Florestal Nacional na Amazônia, Cerrado e Caatinga, e no inventário em Santa Catarina, representando Floresta Ombrófila Mista e Floresta Estacional Decidual. O comparativo do coeficiente de variação, para transectos de 10 a 150 m indica que as maiores alterações desse estimador ocorrem no intervalo de 10 até 50 m, estabilizando-se a partir deste comprimento. A adoção de transectos de 10 m nas tipologias avaliadas é recomendável, pois com este comprimento ocorre uma redução de 35% na distância total de caminhamento em... |

| A Floresta Ombrófila Mista é considerada uma das principais formações do bioma Mata Atlântica. Apesar de sua importância, existe uma carência de informações sobre a dinâmica de crescimento de espécies dessa tipologia florestal. O presente estudo foi desenvolvido com o objetivo de estimar o crescimento passado de espécies arbóreas de Floresta Ombrófila Mista. Foram realizadas avaliações dendrocronológicas não destrutivas nas espécies Araucaria angustifolia, Ocotea porosa, Ilex paraguariensis, Cedrela fissilis, Ocotea puberula e Ocotea pulchella. O crescimento periódico médio em diâmetro até 2006 foi de aproximadamente 0,5 cm ano-1, para A. angustifolia, C. fissilis, O. porosa e O. pulchella. O. puberula e I. paraguariensis apresentaram crescimento periódico... |

| Araucaria Forest is one of most threatened phyto-physiognomies in the Atlantic Forest domain,presenting great ecological-economical importance. Nevertheless, there are still lacks of knowledge concerning growth and dynamic of important species, as Araucaria angustifolia. The objective of this work was to recover the past growth of Araucaria angustifolia, native from Caçador, SC, Brazil, by measuring growth rings and to estimate the average periodic diametric increment. The growth rings were counted and measured, using a stereoscope microscope, in increment cores of 0.5 cm collected from 32 adult trees. The measurements were done with LINTAB measuring table, with 0.01 mm of precision. The samples sizes were irregular, varying from 4.2 to 20.2 cm long. The... |

| This 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 area and a spacing of 5 x 5 m between trees belonging to the same species was adopted. There were planted 123 parana-pines and 96 imbuias. Thirty-five trees, which remained after the fire, were also left in the area. Parana-pines were firstly planted by seed, but due to the attack of Cebus apella nigritus on the newly emerged plants, it was... |
