Resumo: This study aims to characterize a native production area (native erval) through silvicultural procedures, productivity and density of Ilex paraguariensis St.-Hil. (erva-mate) and also the floristic, phytosociology, and diameter structure. To identify the silvicultural procedures, we used semi-structured interviews. For productivity assessment, the commercial biomass of I. paraguariensis was determined. For vegetation assessment, two permanent sample plots totaling 1.25 ha were installed, considering all individuals with circumference at 1.30 m above soil level (CBH) ≥ 31.4 cm, for which it was registered CBH, botanical identification, XY coordinates in the plot, and all the individuals of I. paraguariensis composing the production system. Silvicultural procedures were characterized by mowing, canopy opening and conduct of natural regeneration, promoting I. paraguariensis, Araucaria angustifolia (Bert.) Kuntze, and cattle. I. paraguariensis density was 634 trees.ha-1, with 2,030 kg.ha-1 of productivity in three-year crops. We found 22 species, with a predominance of Myrtaceae and Aquifoliaceae. The species of highest importance value and coverage was A. angustifolia. The diameter distribution showed a higher concentration of individuals in the smaller classes.

(erva-mate) e caracterizar quanto à florística, fitossociologia e estrutura diamétrica do remanescente florestal. Para identificar os procedimentos silviculturais, utilizou-se entrevista semiestruturada. A produtividade foi determinada pela biomassa comercial de I. paraguariensis. Para a análise da vegetação, foram instaladas duas unidades amostrais permanentes, somando 1,25 ha, onde foram considerados todos os indivíduos com circunferência a 1,30 m do solo (CAP) ≥ 31,4 cm, dos quais se registrou o CAP, a identificação botânica e as coordenadas XY na parcela, além de todos os indivíduos de erva-mate compondo o sistema produtivo. Os procedimentos silviculturais se caracterizaram pela roçada, abertura do dossel e condução da regeneração natural, favorecendo I. paraguariensis e Araucaria angustifolia (Bert.) Kuntze, além da criação de gado bovino. A densidade de I. paraguariensis foi de 634 árv.ha-1, com produtividade de 2.030 kg.ha-1 em colheitas trienais. Foram encontradas 22 espécies, com predominância de Myrtaceae e Aquifoliaceae. A espécie de maior valor de importância e de cobertura foi A. angustifolia e a distribuição diamétrica mostrou maior concentração de indivíduos nas menores classes.Embrapa Florestas2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/89810.4336/2015.pfb.35.83.898Pesquisa Florestal Brasileira; v. 35 n. 83 (2015): jul./set.; 199-208Pesquisa Florestal Brasileira; Vol. 35 No. 83 (2015): jul./set.; 199-2081983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/898/428Signor, PabloGomes, Gabriela SchmitzWatzlawick, Luciano Farinhainfo:eu-repo/semantics/openAccess2017-04-28T12:42:02Zoai:pfb.cnpf.embrapa.br/pfb:article/898Revistahttps://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:2017-04-28T12:42:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
