Item Potencial das árvores urbanas na regulação hídrica em ruas da cidade do Recife – PE(2019-12-06) Oliveira, Bianka Luise de; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/2234337737762536Urban trees have the ability to intercept rainwater through their leaves, surface branches and logs, slowing down the peak flow and reducing runoff. Given this, this study aimed to estimate the potential of water regulation of urban trees in the neighborhood of Graças in Recife - PE with the help of the i-Tree platform to quantify the volume of intercepted water and avoided runoff by trees. A tree inventory was conducted in 4 streets of the neighborhood following the platform models and protocols. The data were entered into the i-Tree Eco v6 program, which aims to quantify and value urban tree ecosystem services. With an intuitive and easy-to-use interface, the program generated reports on interception and avoided runoff at individual and species level, crown health, breast height diameter (DBH) classes, crown area, leaf area, and frequency of species. In 2016, 137 trees intercepted 1,739.8 m³ of rainwater and avoided 355.1 m³ of runoff. The most frequent species were Licania tomentosa (21.17%), Senna siamea (11.68%), Terminalia cattapa (9.49%) and Filicium decipiens (8.03%). Among the most frequent species, L. tomentosa presented the highest total interception and T. catappa presented the highest average interception value of its individuals. The same sequence occurred for the avoided runoff values. The species Lagerstroemia speciosa presented the lowest values of interception and avoided runoff. Most of the individuals of the most frequent species presented crowns in bad and critical conditions. The species L. tomentosa presented larger crown area and volume, followed by T. catappa and S. siamea. The values of interception and avoided runoff showed that they are directly related to the tree area, volume and health of the crown. The results illustrate that the platform is very useful in the study of ecosystem services provided by Brazilians’ cities urban afforestation. Despite some limitations for international projects, the platform works satisfactorily. The products generated by the i-Tree Eco v6 program can assist in the planning and management of urban trees.Item Análise qualitativa de espécies plantadas no bairro da Encruzilhada, Recife-PE(2019-07-15) Nascimento, Isabelly Meg Freitas do; Feliciano, Ana Lícia Patriota; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/4744657711055499The disorderly growth in urban centers has compromised the quality of life of the population, and the dispute between the environment and the anthropic constructions brought structural problems to the urban environment. The search for the minimization of the impacts caused by this lack of planning is based on the idea of a sustainable environment, which refers to economic growth taking into account the environmental variables, therefore, the urban forestation represents a mean to achieve this objective, and also exercises a primary role in providing physical and psychological benefits to the population. The present study aimed to carry out the qualitative inventory of a planting carried out in 2016 in the neighborhood of Encruzilhada, in the city of Recife-PE. The following qualitative parameters were evaluated: tree name, CAP, phytosanitary status, tree size, height of first bifurcation, canopy status with regard to phytosanitary status and torso status in relation to tortuosity and bifurcation, height total, need for maintenance. The results obtained showed that after three years of planting, only 29% of the individuals planted in the year 2016 were lost, in relation to the species found the following results were obtained: 29,58% Pata de Vaca (Bauhinia monandra Kurz), 26,76% of Resedá (Lagerstroemia indica L), 22,54% of Ipê Branco (roseoalba (Ridl.) Sandwith) and 21,13% of Sabonete (Sapindus saponaria L). Regarding the plant health, 62,94% were in good conditions, 24,48% under regular conditions, 11.89% under bad conditions and 0,70% were dead. In the maintenance needs, 55,30% of the trees need pruning, 25,76% did not require any type of maintenance and 18,94% needed other types of maintenance.Item Detecção de árvores individuais por meio do lidar para a gestão da arborização do Campus-Dois Irmãos da UFRPE(2019-07-11) Gomes, Rayane Mireli Silva; Silva, Emanuel Araújo; Silva, Vanessa Souza da; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/0663135141305608Urban forests are elements that promote the balance between urban and rural environments, presenting important social, political, economic and architectural character, besides providing an improvement in the population's quality of life. LiDAR is a technology that has been used in forest applications with certain frequency growth, mainly due to the fast availability and access to data and its accuracy. Forest inventory is an essential activity for the qualitative and quantitative knowledge and characterization of forest areas, but it is very time consuming, so many companies and professionals are using remote sensing techniques to optimize the performance of the activity, in terms of time, cost and efficiency. With the constant improvement of technologies, remote sensing became part of the techniques and methodologies used in the monitoring and management of green areas. Automatic detection of individual trees is a fundamental procedure for studies that aim to extract dendrometric data at tree level, height, for example, is a measure that in the field can be difficult to obtain in the traditional way. These data from individual trees allow us to represent canopy and / or canopy characteristics, as well as future analyzes and structural and floristic characterizations of the vegetation. Given the above, the objective of the present work was to explore the potential of airborne LiDAR data for detecting individual trees in an urban forest area at the UFRPE headquarters campus, using Fusion, the technology has as its principle a laser scanning of a terrain emitting pulses at a high frequency and calculating the return time of these pulses to the sensor, forming a cloud of dots mapping the terrain below. Using the Fusion software, soil and surface separation was performed using the Groundfilter command, followed by the creation of digital terrain and surface models using the GridsurfaceCreate command. Still in a Fusion environment, a digital canopy model (CHM) was created using the Canopymodel command. After processing, data analysis was performed in RStudio, using packages and functions specific to this type of processing. In the FindTreesDetection function, three filter window sizes were used, since the study refers to the vegetation area without standard spacing. The results showed that in the study area, as calculated by RStudio, based on the 3x3, 5x5 and 7x7 filter windows, there are, respectively, 6,263, 2,356 and 1,367 trees identified during processing.Item Diagnóstico da arborização de vias públicas no entorno dos reservatórios elevados de água no município de Paulista-PE(2018) Silva, Satyro Barbosa da; Duarte, Simone Mirtes Araújo; Silva, Hernande Pereira da; http://lattes.cnpq.br/1800835100486343; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/6865576903260120The benefits that urban tree-planting provides to communities where there are established trees, such as providing shade for pedestrians, physical soil stabilization, reducing the impact of rain, avoiding heat islands and biological deserts, provide scenic beauty and psychological well-being are indisputable, barring or channeling the wind and dampening the sound. However, there are many difficulties encountered in establishing an afforestation project in consolidated urban communities, mainly due to lack of planning, adequate urban furniture, telephony, sanitation and electrical equipment. Trees are sometimes considered as negative points of conflict, being blamed for destroying sidewalks, disrupting electrical wiring, breaking pipes and causing accidents by falling branches or falling over. Based on the principle that the more trees, the better the thermal sensation and the less the need to use treated water in the search for this balance, this work proposes an afforestation project around the five reservoirs administered by Companhia Pernambucana de Saneamento – COMPESA, as a way to benefit communities, not only with sanitation, but also with afforestation. For that, aerial-photogrammetric images of 0.50 x 0.50 m resolution were used, the census of the trees was carried out in the surroundings of the five reservoirs used in the study of the city of Paulista, from which several indices were obtained that allowed to evaluate and elaborate an afforestation plan in the roads that offered the physical conditions to do so. A total of 1,222 individuals were collected, distributed in 19 botanical families and 43 species, in which 86.7% of the species are exotic to the Brazilian flora and 13.3% are native. The most frequent species around the reservoirs were: Ficus benjamina L. (29.7%), Roystonea oleracea (Jacq.) O.F. Cook. (11.3%) and Terminalia catappa L. (10.8%). Based on current standards and similar literature, localities, quantity, adequate distance and species to be planted on the public, road were proposed in order to bring back the well-being that the population needs, totaling 415 trees distributed in 15 species of native origin. The study also shows the need for public intervention through campaigns to raise awareness of the importance of trees and especially in the structuring of roads that lack proper attention.
