Estrutura da paisagem e a conectividade entre os fragmentos florestais do entorno da Cidade Universitária do Estado do Amazonas

Abstract

The municipality (county) of Iranduba is undergoing for an accelerated process of urbanization under the influence of major infrastructure projects such as construction of the Rio Negro Bridge, doubling the width of the Manoel Urbano Highway and, recently, the building the “University City” of the State University of Amazonas. The region closest to Manaus has undergone rapid change in its landscape because of human occupation and urbanization of the area. This is the region where the Environmental Protection Area (APA) of the Right Bank of Rio Negro located. Despite a long history of anthropic action, this APA still has remaining forest. This study presents an evaluation (for the purpose of conservation) of landscape structure and connectivity among forest fragments surrounding the University City. Through landscape metrics calculated using the Fragstats 4.2 program, the number of the fragments was quantified and a structural analysis of these forest fragments was carried out in terms of total area, core area and the composition fragment edges. Finally, four forest fragments were detected near the University City with areas greater than 100 ha that have important characteristics for environmental conservation.
