Item Análise das características dos índices de vegetação em um plantio de Eucalyptus spp. utilizando imagens do Sentinel-2A(2023-09-14) Silva, Adailton Domingos Salustiano da; Silva, Emanuel Araújo; Sá, Vânia Aparecida de; http://lattes.cnpq.br/5807408661337266; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/7511858370212406Item Zoneamento agroclimático para plantio de Eucalyptus urophylla na Zona da Mata de Pernambuco(2024-02-19) Silva, Carlos Antônio Campelo Cavalcanti; Silva, Emanuel Araújo; Almeida, Débora de Melo; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/1534900496128952The state of Pernambuco, encompassing the biomes of the Atlantic Forest and Caatinga, faces challenges of degradation, especially in the Atlantic Forest, extensive sugarcane cultivation has resulted in forest fragmentation of biome, with impoverished and abandoned areas. The study suggests reestablishing the use of these degraded areas considering market demand, with the main objective of conducting an agroclimatic zoning of areas suitable for eucalyptus plantation in the Zona da Mata of Pernambuco. To achieve this, data on average air temperature and precipitation were collected from four meteorological stations distributed in the region. Using these data, monthly climatic water balance was calculated following the method proposed by Thornthwaite and Mather (1955). Subsequently, the data were processed and mapped using a Geographic Information System (GIS) environment using QGIS 3.16 software. The agroclimatic zoning was elaborated considering the climatic requirements of the Eucalyptus urophylla species, highlighting areas with thermal and water conditions suitable for cultivation. The results showed that approximately 28.95% of the analyzed territory in the Zona da Mata is suitable for the development of the species, concentrating in 16 municipalities surrounding the Metropolitan Region of Recife. This potential area totals 2428 km². On the other hand, approximately 71.05% of the studied area was considered unsuitable due to identified levels of water deficit. These results can contribute to land use planning, promoting more sustainable and effective cultivation practices in the region.Item Anatomia das fibras da madeira de clone de Eucalyptus urophylla plantado em diferentes espaçamentos no estado de Pernambuco(2022-10-06) Lima, Giúlia Stéphane Ribeiro de; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/4737148240951906Eucalyptus represents the most important exotic forest genus in Brazil and has been widely used in forest plantations. Knowledge of the anatomical characteristics of wood such as vessel volume and fibers are factors in the physical and mechanical properties of wood as well as indicative of the final use of wood. The anatomical structure of wood exerts a direct influence on wood density, which also directly influences anisotropy. As a result, these are closely correlated properties. The spacing has a great influence on the quality of the forest site, as it is a sum of the factors that interfere in the productivity of the forest stand. The present study aimed to anatomically analyze the morphology of the fibers of an eight-year-old clone of Eucalyptus urophylla, collected at the Estação Experimental do Araripe, in Araripina - PE, planted in different spacings (2 x 1m (T1), 4 x 2m (T2) and 3 x 2m (T3)) to qualify for use in pulp and paper production. For, clone trees were used, five in each plantation, where a sample composed by treatment was carried out. The preparation of the samples consisted of the dissociation of wood fragments, carried out by means of a macerating solution. The operations were performed through the provisional slides, using an optical image acquisition system with the R 25 image acquisition system. ImageProPlus software was used to capture images and measure the fibers. The Runkel Index, the Felling Index were calculated and the Coefficient of Flexibility, Coefficient of Stiffness and the Wall Fraction of the treatments were determined. The determination of the basic density was obtained through the relation of the dry mass and its saturated volume. The fiber dimension values were compared to each other with significant mean differences between treatments, which demonstrate to be a selection of a spacing. ideal in order to achieve greater productivity. Results were obtained and approved for the presentation, as it presents characteristics with similar characteristics. Protective and paper protection fit adjustments protected when compared to spaces, treatment 2 being with protection and paper reinforcement.Item Histórico das mudanças nas classes de uso e cobertura do solo nas fazendas da Eucatex no estado de São Paulo(2022-09-27) Silva, Yasmim Victória de Araújo e; Berger, Rute; Marques, Luísa Pereira; http://lattes.cnpq.br/1603075418219366; http://lattes.cnpq.br/5395827385005105; http://lattes.cnpq.br/0643141145421813The consumption of forest-based products has increased in recent decades and forestry has been considered a strategic segment to collaborate and encourage the increase in the production of wood products. Until 2019, forest plantations represented about 9.8 million hectares in Brazil. The first land use and land cover classification system with remote sensing data aimed to identify the different categories of land classes. Land cover changes can be related to conversions, which are the complete replacement of one type of cover with another. The objective of this work was to measure the conversion of areas in forest management farms planted with Eucalyptus sp. of Eucatex Florestal, which are the scope of forest certification (FSC-FM), following the natural forest in an interval of up to 27 years (1994 – 2021). The study areas correspond to 51 Eucatex Florestal farms in the regions of Botucatu, Sorocaba and Bauru, in the state of São Paulo, distributed in 18 municipalities. In this study, Eucalyptus is not planted in conjunction with natural forest, but at the stands for commercial purposes, and areas with native species are separated by setbacks or trails. Imagery from satellite Landsat 5, 7, and 8 was used, depending on availability for the requested date. The images were downloaded from the Earth Explorer website and the maximum likelihood method was applied. Of the 51 farms analyzed, 43 had an increase in their natural forest areas and only eight had some type of vegetation loss. The Morrinhos Radar farm showed the greatest increase in the “natural forest” class since 1994, totaling 455.13 ha converted. The Santa Filomena farm had the greatest area loss, with 39.82 ha of its natural forest areas lost, and the other seven farms lost less than 10 ha. There was a increase in the natural forest cover spontaneously, without the application of forest restoration techniques, only with the isolation of the areas. The farms lost more area of natural forest before being acquired by the company, whereas after the implantation of the Eucalyptus stands, there was an increase in the natural areas. The culture of Eucalyptus sp. did not interfere with the regeneration of natural forest areas.
