SUMMARY:

In the midst of the traditional gray infrastructure present in urban environments, afforestation proves to be an important biotic component, capable of minimizing the negative externalities resulting from urbanization. However, in many Brazilian municipalities, afforestation is not included in urban planning, favoring the emergence of incompatibility situations. This reality is also present in the municipality of Teixeira de Freitas, located in the extreme south of Bahia. Given this perspective, the aim of this work was to obtain an overview of urban forestry in Brazilian cities, as well as to carry out a qualitative and quantitative characterization of the urban forestry of four transects of Teixeira de Freitas, in order to propose measures that support a Master Plan Sustainable Development of Urban Forestry for Teixeira de Freitas, compatible with the Sustainable Development Goals - SDGs of the 2030 Agenda. To this end, a systematic literature review was carried out, based on the PRISMA 2020 methodology, and, based on the selected records, a list of species, determining the origin, form of life, frequency of species, and the abundance of individuals used. The distribution of studies by region, state, and the main problems encountered in afforestation in Brazilian cities was determined. On a local scale, a qualitative and quantitative inventory was carried out of the trees present in seven squares, three streets and three avenues, which correspond to four stretches, covering an area of approximately 339,348 m². In the literature review, 2,486 records were raised, of which 197 were selected. The Southeast and South regions stand out with the highest number of publications (29%, N=58; 28%; N=56). From the selected articles, a list of 1,079 taxa was obtained, with 109 families and 938 species determined. Fabaceae is the most representative family (19%; N= 208), and Ficus benjamina and Mangifera indica are the species with the highest citation frequency (70%). As for the origin, 46% of the species are exotic and 54% are native, however, 58% of exotic and 42% of native were used in the analyzed studies, indicating a prioritization of exotic in the implantation of afforestation, despite the high richness of native species in Brazil. While in the survey of urban afforestation in Teixeira de Freitas, 1,217 individuals were registered, belonging to 114 species and 41 families. Highlighting Chrysobalanaceae as the family with the highest density (30%), represented by the species Moquilea tomentosa. Species of exotic origin were predominant (76%). The Shannon-Weiner Diversity Index revealed good diversity (H'=3.207). Regarding the dendrometric aspects, the following averages were obtained: 7.34 m of total height; 1.67 m in height at the first fork; 0.38 m in diameter at chest height; 7.10 m canopy diameter, 57.41 m² canopy projection area, and 19% canopy projection area. As for the physical-sanitary aspects, there was a predominance of individuals with healthy crowns (63%), intact trunk (58%), without pruning (74%), vigorous (47%), underground root (58%), without damage to the sidewalks (66 %), with adequate free space (90%). The most common conflicts were with wiring (21%), inadequate distance between trees (44%), facades (15%) and lamp posts (14%). Therefore, a greater commitment on the part of the competent bodies towards this theme becomes necessary, and it is hoped that the data presented here can provide subsidies to make Brazilian cities more sustainable, especially Teixeira de Freitas.
