O BIOGEOGRAFIA: UMA ANÁLISE DA VEGETAÇÃO NAS CIDADES DE BOA ESPERANÇA, FAROL E JANIÓPOLIS

Abstract

This research aims to carry out a biogeographical study of the urban street tree vegetation and the vegetation of backyards in the capitals of the municipalities of Boa Esperança, Farol and Janiópolis, with the aim of understanding the role of phytogeography in the dynamics of the urban ecosystem. In this research, bibliographic and field materials will be contemplated, in addition to analyzes and discussions, involving a universal inventory of individuals present on the public roads of the three municipalities and considering the streets of the urban perimeter. Therefore, this research emphasizes the biogeographical aspects of vegetation, focusing on the vegetation of small towns and the quantification, distribution and tree frequency found in them. Through field work, it was possible to generate a tree inventory of public roads and the generation of primary data, with which products, analyzes and discussions were carried out, about the optimization of resources, in addition to the use of planning as a management tool urban. The main results found were: visualization of urban vegetation, modification of the vegetational design of cities, composition of species present in street vegetation, in the municipal seats; number of tree species present on the roads; patterns of urban vegetation. The main results, considering the three municipalities, were the following: in Boa Esperança, the largest number of individuals in the research was found, with 3,144 specimens, mostly composed of the Privet species, representing 92% of the road vegetation; at Farol headquarters, the smallest number of specimens was georeferenced, with only 1,240 individuals of arboreal size, but with the greatest variety of species, representing 79 species; for the city of Janiópolis, 1,842 individuals and 45 different species were found. As part of the results and analyses, gaps were identified in the urban street vegetation in the cities of Farol and Janiópolis, generating the discontinuity of vegetation and a decrease in the private urban mass due to the increase in urban furniture. It is concluded, therefore, that the study areas are in vegetation deficit, which raises concern due to the quality of life of society in full contact with the areas, in addition to the reduction of shelter for the local fauna.
