Abstract

Abstract Urban greening provides several environment functions and services in cities. Although scarce, temporal evaluations of afforestation in cities are essential for the plants management and the proposition of municipal public policies. We analysed the woody dynamics of the urban greening in Jataí, Goiás, Brazil, over 13-years (2007–2020), considering variations in tree composition, diversity, and structure. We also evaluate ecosystem services (pollination, dispersal and fruit supply) and planting management (native and non-native species, tree planted under electricity lines and sidewalk). Both species richness, diversity and equability increased in 2020. The density of anemophilous species increased in 2020, while the other pollination mechanisms remained constant. Zoochory prevailed with higher species richness and density in both years, while the fruit and non-fruit species richness and density increased. Although the richness of native species increased, the density pf non-native was higher than native species in 2020. The density of large species density has increased under electricity lines, suggesting inadequacy of tree planting over the years. Species density in the furniture and frontage zones increased in 2020, while there was no difference in the pedestrian zone between years. Increasing tree density improves the connection between urban forests and parks, which contributes to the well-being of the population in cities with a tropical climate, such as Jataí. Our study shows that long-term urban greening assessments provide input for public policies.
