Resumo: The aim of this paper was to know and analyze the floristic composition and describe the structure of the arboreous component of a fragment of Montane Mixed Ombrophylous Forest in Criúva – State of Rio Grande do Sul, Brazil. Were inventoried 673 individuous with DBH ³ 5 cm eight 10 x 100 m plots, distributed into 37 species, 32 genera and 22 families. The Shannon diversity index was 2,768. The families which presented the largest number of individuous were: Araucariaceae, Myrsinaceae, Euphorbiaceae, Anacardiaceae and Rutaceae. The forest canopy is dominated by Araucaria angustifolia and the understory, by species of the families Lauraceae and Myrtaceae. The total density found was 841,25 individuous/ha, the mean DBH was 24,01 cm and the highest VI values, in descending order, were: Araucaria angustifolia, Sebastiania commersoniana , Lithraea brasiliensis, Zanthoxylum rhoifolium and Myrcia sp.. The fragment presents a considerable floristic diversity of species, in spite of the suffered disturbances in the past. For the vegetation to reach the floristic and structural characteristics close to the one of the original vegetation it is necessary to avoid the presence of bovine and equine in the area and explorations of the forest.

Em oito parcelas de 10 x 100 m foram inventariados 673 indivíduos com DAP  5 cm, distribuídos em 37 espécies, pertencentes a 32 gêneros e 22 famílias. O valor do índice de diversidade de Shannon foi de 2,768. As famílias que apresentaram maior número de indivíduos amostrados são: Araucariaceae, Myrsinaceae, Euphorbiaceae, Anacardiaceae e Rutaceae. O dossel dessa floresta é dominado pela Araucaria angustifolia e o sub-bosque por espécies das famílias Lauraceae e Myrtaceae. A densidade total encontrada foi de 841,25 indivíduos/ha, com DAP médio de 24,01 cm e altura média de 9,34 m. As cinco espécies que tiveram os maiores valores de importância, em ordem decrescente, foram: Araucaria angustifolia, Sebastiania commersoniana, Lithraea brasiliensis, Zanthoxylum rhoifolium e Myrcia sp.. O fragmento apresenta uma considerável diversidade florística de espécies, apesar das perturbações sofridas no passado. Para que a vegetação atinja as características florísticas e estruturais próximas às da vegetação original é preciso evitar a presença de bovinos e eqüinos na área e explorações da floresta.Universidade Federal de Santa Maria2002-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/169810.5902/198050981698Ciência Florestal; Vol. 12 No. 1 (2002); 29-37Ciência Florestal; v. 12 n. 1 (2002); 29-371980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1698/973Rondon Neto, Rubens MarquesWatzlawick, Luciano FarinhaCaldeira, Marcos Vinícius WinchlerSchoeninger, Emerson Robertoinfo:eu-repo/semantics/openAccess2017-06-05T14:19:02Zoai:ojs.pkp.sfu.ca:article/1698Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-05T14:19:02Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
