    The forest inventory is an essential tool for accurate forestry planning, with the aim of obtaining a homogeneous forest in the future with good expressiveness in terms of diameter and height. The study area was a sugar-alcohol company located in the Zona da Mata Norte region of Pernambuco, in the municipality of Tracunhaém. In order to have a quality forest, it is necessary to periodically monitor the stand from the time the seedlings are planted in the field until they are harvested. The aim of this study was to assess the survival and quality of Eucalyptus hybrids (Eucalyptus urophylla x Eucalyptus camaldulensis) using two sampling methods, using the Pv50% uniformity index. The inventory was carried out at 3 months and 14 months using the circular plot and systematic line sampling methods. The planting was done at a spacing of 3m x 3m in an area close to a community that used it to dispose of its solid waste. Systematic sampling was carried out by randomly establishing the start of the systematic sampling sequence and followed the sequence established for data collection. The sampling per plot was 6 meters long and 113m² in area. The data obtained made it possible to generate information on the percentage of survival, planting failures and mortality, with the systematic line sampling method performing more efficiently, as it generates reliable information when it comes to observing trends in a forest. Survival by systematic sampling at 3 months ranged from 85% to 66% survival, and at 14 months 78% to 63%, while the circular plot method at 1 month had a percentage of 94% to 100% survival and at 14 months 72% to 99%. The study showed satisfactory sampling sufficiency, with a 9% sampling error being admissible, and a coefficient of variation of 43%, showing high variability in the volume of samples. The uniformity index Pv50% of the plots had 37% uniformity, indicating that the silviculture applied to the areas did not provide equal growing conditions for the hybrids. When analyzing the sampling methods based on the analysis of variance statistics, it was possible to see that the systematic sampling method was significant and more efficient for carrying out a survival inventory.

    Abordagem comparativa entre a aplicação da metodologia KATAM e inventário tradicional em plantios de Khaya senegalensis (Desr.) A. Juss
    (2023-09-15) Silva, Kamilo Alaboodi da; Silva, Emanuel Araújo; Hakamada, Rodrigo Eiji; http://lattes.cnpq.br/4186459700983170; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/5612600854790108
    The forest inventory helps forest managers taking decisions. Installing, measuring and managing a network of inventory plots is a costly and time-consuming activity. The remote sensing techniques are increasingly gaining ground in the forestry sector because they have the potential to reduce costs without incurring any loss of precision, but they are not widely used due to their high cost. In this context, the Swedish company Katam Technologies has developed a solution for acquiring and analyzing forest data: KATAM Forest, which works using the KASLAM algorithm, which has not yet been widely used and tested in national forests. The goal of this study was to compare, in terms of accuracy and operational performance, the application of KASLAM artificial intelligence through the KATAM Forest application in forest inventory activities in Khaya senegalensis (Desr.) A. Juss plantations (5 years old), located in the state of Pernambuco, with the sampling techniques of a traditional forest inventory. Diameter at breast height (DBH) data was collected within 9 plots, as well as videos with artificial intelligence, recorded within the coordinates of the sampling units. Descriptive statistics were performed on the DBH data by plot, followed by the parametric Shapiro-Wilk normality test, where, if the null hypothesis was rejected, a non-parametric Mann-Whitney U test was required to understand the difference in averages. Operational performance was assessed using the time data obtained during the inventory process within the plots in both approaches. The DBH variable in the two inventory methodologies does not have a clear distribution concentrated close to the mean. The non-parametric test resulted in the averages obtained for DBH not showing statistical differences between the methodologies at the 5% significance level. The operational performance of the Katam methodology was half of the traditional inventory. The Katam technologies are very promising in terms of reducing time and costs in forest inventory operations. Therefore, further studies are recommended so that the subject can be disseminated in a practical way.

    Diagnóstico da arborização urbana das principais vias de Ibimirim, Pernambuco
    (2022-10-06) Silva, Mariana Sophya Bezerra da; Duarte, Simone Mirtes Araújo; Vasconcelos, Géssica dos Santos; http://lattes.cnpq.br/0802316667174979; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/1589553305898562
    Urban forestry provides a number of benefits for the environment and society, however, strategic planning is necessary so that the needs are met and the species are best adapted to the desired location. This study aims to use the techniques of geoprocessing applied to urban forestry, in order to perform a survey and evaluation of the individuals present in the main access roads to the city of Ibimirim - PE, in order to provide a database for the construction of a specific Urban Forestry Manual for the municipality. The data collection was carried out in April 2022, under the route of its main roads in the city, all individuals that were on the margins, in central beds or public squares located along this route were inventoried, through a Census inventory and with the use of a field form. Trees, shrubs, cacti and bushes were georeferenced using SurveyCam software available for smartphones, providing decimal longitude and latitude coordinates in order to create thematic maps with the arrangement of individuals through GIS. Through this collection, 412 individuals were inventoried, represented by 14 species, 14 genera and 09 botanical families, where 97% are trees, of these trees 81% are in the adult stage and 16% with drastic pruning, the care of the individuals observed in loco, were performed by the local population.
