Item Parâmetros fitossociológicos e índice de perfomance na arborização de ruas de Recife, Pernambuco(2025-02-10) Novais, Maria Eduarda Silva de; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/1071037415624656The phytosociological study of urban trees is an important tool for planning, maintaining and managing tree planting in cities. Understanding the floristic composition and phytosociological structure of urban environments is fundamental to understanding the dynamics of vegetation, as well as providing support for the implementation of actions aimed at conserving and improving diversity in these areas. With this in mind, the aim of this study was to analyze the adaptation and performance of the species present in the street trees of Recife-PE. The research was carried out on 4 (four) sample units measuring 350 meters x 560 meters, randomly selected from the inventory of street trees carried out by Biondi (1985) in Recife, Pernambuco. The species present on the sidewalks were identified and the phytosociological parameters, Absolute and Relative Frequency (AF and FR), Absolute and Relative Dominance (DoA and DoR), Absolute and Relative Total Density (DT, DA and DR), Absolute and Relative Importance Value (VI and VI%), and the Performance Index (IPE) were estimated. A total of 528 individuals were counted, distributed among 59 species belonging to 19 families. It was observed that 67,86% are of exotic origin from Brazil, which is one of the main causes of biodiversity reduction. The species with the highest number of individuals were Senna siamea (87 individuals), Ficus benjamina (64 individuals) and Adonidia merrillii (53 individuals). The phytosociological analysis showed that Pithecellobium dulce was the most dominant (19,99%), followed by Terminalia catappa (14,31%) and Senna siamea (13,85%). In erms of relative density, Senna siamea (21,48%), Ficus benjamina (16,79%) and Pithecellobium dulce (6,67%) showed a lower diversity of species in the areas studied. The VI was highest for Senna siamea (13,40%), followed by Ficus benjamina (10,97%) and Pithecellobium dulce (10,11%). The species with IPE above 1,0 were Handroanthus impetiginosus, Hymenaea courbaril, Schinus terebinthifolia, Apeiba tibourbou, Cassia fistula, Cassia javanica, Genipa americana and Bauhinia monandra, which continue to be included in Recife's afforestation. It is recommended that measures be taken to introduce species of native origin, and possibly to gradually replace individuals, helping to reduce the concentration of individuals in a few species, with the species Handroanthus impetiginosus and Bauhinia monandra, which were promising in relation to the values for IPE and VI%.Item Planejamento da arborização urbana: estudo de caso da Avenida Duque de Caxias, São Lourenço da Mata - PE(2024-10-01) Cravo, Amanda Clarinda de Melo; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969This study focused on urban tree planning along Duque de Caxias Avenue, considering its feasibility and associated costs. The objective was to evaluate the physical conditions of the road and specific challenges, following the guidelines of the Urban Tree Planting Manual of Recife. Small-sized species suitable for sidewalk widths and wire heights were selected, essential to mitigate risks and reduce seedling mortality rates. The methodology included a detailed survey of available planting spaces, identifying 179 viable intervals, albeit limited by the scattered presence of urban elements such as poles and signage boards. The results highlighted the need for 2130 seedlings to cover the planned demand, considering a mortality rate of 50%. Cost assessments from nine local nurseries revealed budgets ranging from R$ 383,400.00 to R$ 440,200.00, emphasizing the complexity and economic challenges associated with acquiring seedlings in a region with scarce available native species. Additionally, a significant gap was identified in the supply of native species seedlings in local nurseries, underscoring the importance of effective policies for urban biodiversity conservation and encouragement of local seedling production. It is concluded that integrated and participatory planning is crucial for the success of urban tree planting initiatives, actively involving local communities, government agencies, and research institutions. This approach not only contributes to improving urban quality of life but also strengthens city resilience in the face of environmental challenges. This study not only provides relevant information for the practical implementation of urban tree planting projects but also highlights the ongoing need for adaptation and innovation in urban policies to promote greener and more sustainable urban environments aligned with sustainable development goals.Item Ações e medidas alcançadas na implementação das diretrizes do Plano Municipal de Arborização de Recife, Pernambuco(2024-03-07) Tavares, Tiago Teixeira Guimarães; Fernandes, Ana Paula Donicht; http://lattes.cnpq.br/7392835869663724Urban afforestation provides multiple benefits, including improvements in climate, air quality, and the physical and mental health of residents, as well as enhancing the beauty of the environment and reducing sound and visual pollution. Careful planning, considering suitable species and preventing planting problems, is essential to maximize these benefits. This study aimed to analyze the implementation of the guidelines of the Urban Afforestation Plan of the city of Recife, Pernambuco. The research is qualitative, involving the collection of documentary data from articles, books, theses, dissertations, municipal legislation, and electronic documents for bibliographic review. Additionally, documents acquired from the Recife Environmental Secretariat were analyzed. Three classifications of actions and measures for the implementation of the Afforestation Plan were defined: planting practice measures, information integration, and educational measures. The results indicated that approximately 90% of the afforestation plan guidelines were implemented, demonstrating the potential for development in the city's afforestation plan. The planting measures category achieved a 50% compliance rate with guidelines related to tree planting in public or private areas, followed by 35% for information integration and 15% for educational measures. Thus, practical planting measures prevail in the afforestation plan, emphasizing the importance of collective efforts for the improvement of urban afforestation in Recife. Therefore, it is recommended to create specific documents, strengthen integration among municipal agencies, and provide financial incentives for afforestation. These coordinated measures can make the city more sustainable and resilient.Item Potencial de falha em árvores utilizando tomógrafo de impulso na Praça da Madalena em Recife/PE(2024-03-05) Silva Junior, Israel Vicente da; Nogueira, Marcelo; http://lattes.cnpq.br/2791448000405507; http://lattes.cnpq.br/2353404237882065In the city of Recife - PE, the falling of trees mainly results from factors such as the absence of well-structured vegetation, due to the occurrence of pests, pathogens, and mechanical failures. Therefore, the structural evaluation of urban trees has become a priority, as the good condition of trees distributed throughout the city is crucial. To perform this evaluation, non-destructive methods, such as impulse tomography, are essential as they do not compromise the mechanical properties of the trees. Thus, the objective of this work was to evaluate the structural condition of the trees in Madalena Square in the municipality of Recife - PE through non-destructive tests. The research was conducted in Madalena Square, where six trees that make up the vegetation of the green area were examined. To evaluate the presence and level of internal deterioration of the tree trunks, the non-destructive analysis method using the impulse tomograph ARBOTOM was used. Furthermore, based on the interpretation of degradation indicative graphs generated by the equipment, it was possible to classify the degree of trunk deterioration, categorizing them with low, medium, high, or severe potential for failure. Of the evaluated individuals, three trees showed a better structural conservation state of their stems. On the other hand, the fourth evaluated tree demonstrated the highest mechanical compromise, as it has termites, boring insects, decaying fungi, as well as poorly executed pruning in its trunk. There is a possibility of the presence of xylophagous agents and decaying fungi, even to a lesser extent, in the core of tree two, since it showed a mechanical failure in its central region, without any external indication of degradation. The third tree, on the other hand, has structural fragility related to the action of mechanical forces, such as traction and compression of fibers, due to its inclination. All trees showed structural fragility caused mainly by the action of xylophagous agents and decaying fungi, in addition to the inclination of the evaluated trunks. Therefore, it is necessary to take actions to replace some tree specimens, considering that the worsening of trunk degradation poses a direct risk to the users of Madalena Square.
