| Resumo: | Public squares are urban green areas which promote the appreciation of nature, offering
opportunities to recreation, community interaction and heathy habits. The vegetation in public
squares interacts with the population mental and physical health, acting directly mainly on
shading and aesthetics of public spaces. This vegetation may present elements selected only
for their ornamental value or act as a form of ex situ conservation and promote the
environmental education of the public. Or even, It may contain elements of the remaining native
vegetation, helping to connect the biota of fragments of native vegetation surrounding cities.
However, the majority of Brazilian cities do not even have control over their urban green areas
and may not have formal knowledge of its floristic composition, what would be essential to
guide the decision making about pruning, removal, implementation or phytosanitary
treatments. In this work, we aimed to expand the knowledge about the urban flora of Natal-RN
through a floristic survey and census of the trees of 90 public squares of the South Zone of
Natal. The exotic and native origin of species was distinguished and indexes and values were
calculated and compiled to better understand the composition, spatial distribution and similarity
to adjacent green urban areas. In total we accounted 28 families, 79 species and 4006
individuals. The most representative species were Cocos nucifera and Anacardium
occidentale and the ones with greater absolute frequency were Mangifera indica, Azadirachta
indica, Anacardium occidentale and Cocus nucifera. Our results show the list of species
composing these green areas, the proportion of exotics and natives, the relative size of public
squares, the number of individuals per area unit, the quantification of total green areas and
usable green areas, the correlation calculated among these variables and the similarity
between the vegetation of the public squares and areas of urban forests. This study highlights
the great amount of exotics in urban spaces and the general bad condition of public green
areas available for the population of Natal. |
