Urban green areas produce benefits such as reduced air pollution, climate mitigation, reduced wind action, less noise pollution, shelter for fauna, and increased water uptake from the soil as well as increased water infiltration to the soil. This work carried out a floristic survey related to its diverse and characterized habit and dispersion, and also related to the origin of the species existing in four public squares within the municipality of Campestre, Minas Gerais. Thus, the floristic and ecological aspects of trees and shrubs were surveyed in four urban green areas of the municipality. All arboreal and shrubby individuals were marked and identified. Each identified species was classified according to habit, dispersion, and origin. In total, 313 tree individuals, shrubs, and palm trees were registered and distributed among 73 species, (62 genera and 30 botanical families). When considering all squares, Shannon’s diversity was 3.72, and Pielou’s evenness coefficient was 0.87. Lower values of diversity and evenness were observed for each public square. There was greater richness and number of individuals of native species compared to exotic ones. The yellow ipe (Handroanthus serratifolius) was the only species present in all studied squares. Sassafras (Ocotea odorifera) and pau-brasil (Paubrasilia echinata) are endangered species and underrepresented. The most represented forms of dispersion were zoochory and anemochory.

Riparian forests play an important role in maintaining environmental services and in conserving species of a genetic corridor for flora and fauna. The present study was carried out with the objective of analyzing the species composition and the horizontal structure at a recovered riparian forest with another native adjacent area in the municipality of Poço Fundo, Minas Gerais. A floristic and phytosociological survey of the arboreal sinusia was carried out in the areas. Were sampled 199 individuals and 24 species in the recovered area and 105 individuals and 23 species in the native area. Floristic similarity between areas was not verified. Shannon diversity was low in both areas. In the recovered area, there is a predominance of early species while in the native area there is a predominance of late ones. There was no floristic convergence between the two studied áreas. A structural convergence between the areas was verified 13 years after the beginning of the restoration.
