Resumo: | Among the different ways of measuring the biotic integrity of a particular forest area, the Rapid Ecological Assessment (REA) stands out. Based on REA, an index was developed to evaluate the quality of the vegetation called the Biotic Integrity Index (BII). The measurement and accuracy of this index show how integral is the forest ecosystem at moment of analysis. The basis for efficiency in the application of BII is the correct choice of biotic integrity indicators or the variables to be measured. The present study was based from an index previously proposed for a Seasonal Semideciduous Forest (SSF), and aimed to adapt the BII for use in an area of Dense Ombrophilous Forest (DOF) in the State of São Paulo as well as to test its efficiency in diagnosing the integrity of fragments of a Tropical Rain Forest (TRF) inserted in a rural matrix. From the eleven indicators present in the original method, some were kept as original or adapted, some removed and some new ones were created. The adapted BII was applied in a TRF area of 70 hectares. To do so, 20 plots of 10x10m were used, within the sampling area. The results showed a variation of IIB from 28 to 47, and 2 plots recorded low integrity, 11 medium integrity and 7 good integrity. The area showed regular integrity as a whole, which was expected due to its size, agricultural surrounding and history of disturbances. The BII showed to be adapted and efficient to analyze the biotic integrity of the DOF, as it was able to show the difference of integrity between different patches of TRF. The least efficient indicators were: "litter cover" and "exotic woody species”, and the most efficient were: “Euterpe edulis”, “epiphytes”, “gaps” and “vines”. |

Diante dos diversos métodos de mensuração da integridade biótica de determinada área de floresta evidencia-se a Avaliação Ecológica Rápida (AER). Com base na AER foi desenvolvido um índice para avaliar a condição da vegetação, denominado Índice de Integridade Biótica (IIB). A aferição e precisão deste índice retratam o quão íntegro um dado ecossistema florestal se encontra no momento da análise. O alicerce para a eficiência na aplicação do IIB está na escolha correta dos indicadores de integridade biótica, ou seja, nas variáveis a serem mensuradas. O presente estudo partiu de um índice anteriormente proposto para Floresta Estacional Semidecidual (FES), e teve como objetivo adaptar o IIB para uso em área de Floresta Ombrófila Densa no Estado de São Paulo, bem como testar sua eficiência no diagnóstico da integridade de fragmentos de Floresta Ombrófila Densa (FOD) inseridos em matriz rural. Dos onze indicadores presentes no método original, alguns foram mantidos como no original ou adaptados, alguns retirados e alguns novos foram criados. O IIB adaptado foi aplicado numa área de FOD de 70 hectares. Para isso, foram utilizadas 20 parcelas de 10x10m, dentro da área amostral. Os resultados mostraram uma variação do IIB entre 28 e 47, ou seja, 2 parcelas registraram integridade baixa, 11 integridade média e 7 integridade boa. A área como um todo apresentou integridade regular, o que era esperado devido ao seu tamanho, ao entorno agrícola e ao histórico de perturbações. O IIB mostrou-se adaptado e eficiente para análise da integridade biótica da FOD, pois conseguiu mostrar a diferença de integridade entre diferentes trechos de Floresta Ombrófila Densa. Os indicadores menos eficientes foram: “cobertura de serapilheira” e “espécies exóticas lenhosas”. Os mais eficientes foram: “Euterpe edulis”, “epífitas”, “clareiras” e “cipós/lianas”.Universidade Federal de Santa Maria2020-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3769810.5902/1980509837698Ciência Florestal; Vol. 30 No. 2 (2020); 489-500Ciência Florestal; v. 30 n. 2 (2020); 489-5001980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/37698/37698Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessScarascia, Pietro OliveiraLeite, Eliana CardosoValente, Roberta Averna2021-05-20T04:00:46Zoai:ojs.pkp.sfu.ca:article/37698Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:46Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
