Quanti-qualitative inventory of urban afforestation in the city of Monte Alegre, Pará, Brazil

Abstract

The survey was carried out in the conditions of urban afforestation in the city of Monte Alegre, Pará, which has no master plan, missing afforestation planning and a systematic diagnosis. Quanti-qualitative diagnosis of the species was conducted with the use of structured spreadsheets, identifying benefits and problems related to their plantations. There were 2,938 plants identified among 64 species, distributed in 56 genuses and belonging to 25 botanical families. The most frequent species was the Yellow Ipê (Handroanthus serratifolius (Vahl.) S.O. Grose), with 312 specimen, which represented 10.6% of the city's trees. The botanical familyFabaceaewas the most represented with 11 species (17,2%) and the most numerous with 518 individuals (17,6%) used in afforestation. It was identified that many trees cause conflicts with electrical wiring (14.4%) while a few others conflict with street public lighting (4%) and traffic signs (1.7%). It was noted the presence of a diversification of species present on public roads, which resulted from the participation of the City Hall of Monte Alegre. Given this, planning of urban forestation and development of a city's master plan are considered essential, in order to provide appropriate criteria and techniques of planting and maintenance to enable the implementation of the expected benefits.
