Resumo: | The studies of landscape ecology from metrics using geoprocessing and remote sensing are important technologies to evaluate the conditions of native forest remnants, especially in biomes fragmented and with a high rate of deforestation as the Caatinga. This study aimed to describe the structure of the forest landscape in the municipality of Ribeira do Pombal, Bahia State, Brazil, using a landscape metric index. The use of soil and forest fragments was characterized using an image of the Landsat-8 OLI satellite. We used the software Fragstats 4.2® to calculate the landscape metrics. Even in a matrix with high percentage of pastures, fragments of the open and dense caatinga of medium and large size predominate in the landscape, with great proximity and connectivity. Reforestation and enrichment of the small fragments of open Caatinga may contribute to form ecological corridors. The great percentage of fragments larger than 100 ha ensures floristic diversity and resilience of the dense caatinga in the municipality of Ribeira do Pombal, BA. |

Este trabalho objetivou descrever a estrutura da paisagem florestal no município de Ribeira do Pombal, BA, por meio de índices métricos da paisagem. Utilizou-se uma imagem do satélite Landsat-8 OLI para a determinação do uso do solo e dos fragmentos florestais. Para o cálculo das métricas da paisagem, foi utilizado o software Fragstats 4.2®. Mesmo em uma matriz com alto percentual de pastagens, predominam na paisagem fragmentos de caatinga aberta e densa de tamanhos médio e grande, com grande proximidade e conectividade. O reflorestamento e enriquecimento dos fragmentos muito pequenos da caatinga aberta podem contribuir para serem utilizados como corredores. O grande percentual de fragmentos maiores que 100 ha garante diversidade florística e resiliência da caatinga densa no município de Ribeira do Pombal, BA.Embrapa Florestas2019-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/168310.4336/2019.pfb.39e201801683Pesquisa Florestal Brasileira; v. 39 (2019)Pesquisa Florestal Brasileira; Vol. 39 (2019)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/1683/906https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessJesus, Janisson Batista deGama, Dráuzio CorreiraNascimento Júnior, José Monteiro doFernandes, Márcia Rodrigues de MouraFernandes, Milton Marques2019-12-31T20:35:26Zoai:pfb.cnpf.embrapa.br/pfb:article/1683Revistahttps://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:2019-12-31T20:35:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
