The 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%.
