Diretrizes técnicas para a elaboração do Programa de Monitoramento Automático de Dados na Arborização Urbana na cidade de Manaus/AM

Abstract

The objective of this work was to characterize the Arborization of Manaus by means of the survey of the species used in the afforestation of this city, with the purpose of creating a Database and to propose technical guidelines for the elaboration of the Program of Automatic Monitoring of the Arborization of the city of Manaus. Tree species were identified and identified in the main avenues and squares of the city. The methodology used was based on an existing database in SEMMAS and field data collection, floristic inventory and spatial analysis with geoprocessing. The evaluation of tree individuals was analyzed from their dendrometric variables as: height (m), diameter class and phytosanitary status. The frequency, density, dominance, importance value and coverage of each species and the diversity index of species were also calculated. There were 2584 individuals distributed in 14 families, 31 genera and 36 species, the highest representation was the Chrisobalanaceae family 1047 individuals. Most of the tree species planted in the main avenues and squares are exotic, with about 68.5% of the urban afforestation. In this way it can be inferred that the urban arborization in the main roads and squares of the city is made up of mostly young individuals with greater representation in the class of DAP between 10.0 m - 19.9 m with 811 individuals and less represented in the class > 80 m with 48 individuals, and the height class most represented: 10.0 - 14.9 m with 924 individuals and less represented the class of 15.0 - 20.0 m with 48 individuals, generally in good condition phytosanitary treatment with 99% of the individuals under these conditions. The city of Manaus does not yet have an Automatic Monitoring Plan, so the guideline proposed in this study will serve as a subsidy for the preparation of this Plan.
