Public squares are examples of urban green areas and as well as acting as refuges for plant
communities with significant conservation potential, they also promote improvements in both
urban environmental quality and the quality of life of the people who frequent them. It is
therefore important that these environments are well planned and wooded. With this in mind,
the aim ofthis study was to survey the plants used in the afforestation ofpublic green spaces in
the municipalities of Oriximiná, Óbidos and Monte Alegre, Pará, Brazil. It also aimed to
compare the urban flora present in these spaces with the flora of the Conservation Units (UCs)
located in these municipalities. The research was carried out in ten public squares, considered
to be the most visited by the local population. Fertile samples were collected from the plants
grown in the squares using basic collection and herborization techniques. Collections were also
made at the Estação Ecológica do Grão-Pará and the Reserva Biológica Maicuru. We identified
the species using dichotomous keys, specialized literature, consultations with specialists and
physical and virtual herbaria. The species sampled were classified according to their origin
(native and exotic). The floristic similarity between the municipalities studied was carried out,
as well as between the flora of the municipalities and the flora of the UCs, and the Shannon
diversity, equitability and dominance indices were applied. Interviews were also conducted with
visitors to the squares in each municipality. Overall, we recorded a total of 4,810 individuals,
50 species, 38 genera and 20 botanical families in the squares. Exotic plants were predominant
in terms of species and number of individuals. A total of 34 species and 22 families were
identified in the UCs. Our analysis showed dissimilarity between the flora sampled in the
municipalities and the flora of the PAs. The municipality of Monte Alegre showed the greatest
diversity and equitability. As a result of the questionnaires, 90 interviews were carried out,
where a positive perception of the presence of vegetation in the urban environment was
observed, and shade stood out as the attribute most cited by them. Finally, we hope to contribute
to the floristic knowledge of urban green areas in the Amazon region and advocate the
valorization of local flora through the use of native species in the afforestation of amazonian
municipalities.
