Inventário florestal urbano e análise fitossanitária das árvores do bairro Agreste: Laranjal do Jari-Ap

Abstract

Forest inventory is essential for cataloging the species that make up urban tree cover and producing qualitative and quantitative data essential for planning and management, while phytosanitary analysis allows for the assessment of tree health and guides corrective interventions when necessary, which is essential for evaluating urban tree cover. Given this, the present study aimed to conduct an urban forest inventory on public roads in the Agreste neighborhood and assess the phytosanitary health of its trees in the municipality of Laranjal do Jari, Amapá. The research adopted a qualitative-quantitative approach, with data collection in loco using GPS, measuring tape, and electronic forms for georeferencing and measurement, and subsequent processing in Microsoft Excel for phytosociological calculations and descriptive analysis. A total of 279 individuals were recorded, distributed among 17 species, with a predominance of Mangifera indica L. and moderate-low diversity (H' = 1.61), reflecting a strong presence of exotic species and an unbalanced structural composition. The phytosanitary analysis indicated that 59.5% of the trees require high management priority, mainly due to contact with electrical wiring, parasite attacks, and inadequate positioning in the urban space. Georeferencing revealed an irregular spatial distribution, with areas of higher concentration contrasting with sections deficient in vegetation cover, evidencing a lack of planning.
