Resumo: We performed an environmental diagnosis study of the watershed Saraiva Stream, located in the municipality of Betim, Minas Gerais State, Brazil, through the identification and characterization of the main springs and forest remnants. In addition to quantification of the total area of forest fragments, it was compared the area subject to environmental restoration of riparian areas when applying the Brazilian environmental legislation represented by old Forest Code - Law nº 4.771/65 and the current legislation, Federal Law nº 12.651/12. Fragments were also evaluate through the landscape metrics in Geographic Information System based on ecological indicators: circularity index; isolation index; total border area; and average size of the spots. The springs and forest remnants in the watershed of Saraiva Stream are in critical condition. Current Brazilian environmental legislation demands smaller total area restoration, compromising the ecological functions performed by riverine ecosystems.

Além da quantificação da área total dos fragmentos florestais, foi calculada a área passível de recuperação ambiental de ambientes ciliares comparando a legislação ambiental brasileira representada pela  Lei Federal nº 4.771, de 15 de setembro de 1965 com a legislação vigente, Lei Federal nº 12.651, de 25 de maio de 2012. Os fragmentos da bacia foram avaliados por métricas de paisagem em Sistema de Informações Geográficas, com base em indicadores ecológicos: índice de circularidade; índice de isolamento; total de área de borda e tamanho médio das manchas. O estado de conservação das nascentes e dos remanescentes florestais na bacia hidrográfica do Córrego Saraiva é crítico. A legislação ambiental brasileira vigente requer menor área total a ser recuperada, comprometendo as funções ecológicas desempenhadas pelos ecossistemas ribeirinhos.Embrapa Florestas2018-08-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/130910.4336/2018.pfb.38e201601309Pesquisa Florestal Brasileira; v. 38 (2018)Pesquisa Florestal Brasileira; Vol. 38 (2018)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1309/674Gomes, Emerson Chaves FerreiraJesus, Edilma Nunes deOliveira, Natália Nogueira deGonçalves Júnior, LuizCabral, Felipe Gonçalves dos SantosResende, Marisa Seoane Rioinfo:eu-repo/semantics/openAccess2019-05-10T19:43:45Zoai:pfb.cnpf.embrapa.br/pfb:article/1309Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-05-10T19:43:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
