Resumo: http://dx.doi.org/10.5902/1980509813320The purpose of this study was to evaluate the floristic composition, the horizontal and vertical structures, as well as the spatial distribution patterns of the tree component in a Steppe Savanna Park located at ‘Parque do Espinilho’, in Barra do Quaraí, Rio Grande do Sul state, Brazil. Floristic composition and phyto-sociological analysis were carried out in a four (04) ha permanent plot (40 000 m²), where all individuals which circumference (C) was ≥ 15.7 cm, measured 30 cm from the ground, were sampled and had their circumference and total height measured. A mean of 145 individuals/ha was found, distributed in 11 species, 10 genera and eight (08) families, with basal area of 4.06 m²/ha. The Shannon Diversity Index (H’) for the tree vegetation was 1.86, and the species with the highest importance values were Prosopis nigra (25.86%), Aspidosperma quebracho-blanco (24.57%), Prosopis affinis (24.30%) and Vachellia caven (10.51%), representing 85.26% of the total. The tree vegetation has two strata, the lower one with 93.3% of the trees and the upper one with only 6.7% of total. The species Aspidosperma quebrachoblancodominated with 70.0% of trees in this stratum. Regarding the spatial distribution pattern of thespecies, Aspidosperma quebracho-blanco presented a grouped tendency, whereas the other ones weregrouped. The savannah steppe park studied is mainly characterized by the occurrence of Aspidospermaquebracho-blanco, Prosopis nigra, Prosopis affinis and Vachellia caven, constituting a unique combinationof species in Brazil, presenting question of rarity in terms of species composition and structure.

Para o levantamento florístico e análise fitossociológica foi instalada, em uma área de ocorrência de Aspidosperma quebracho-blanco, uma unidade permanente de 4 ha (200 x 200 m), onde todos os indivíduos com circunferência (C) ≥ 15,7 cm a 30 cm do nível do solo foram amostrados e medidas a circunferência e altura total. Foram encontrados 145 indivíduos/ha, distribuídos em 11 espécies, 10 gêneros e 8 famílias, com área basal de 4,06 m²/ha. A vegetação arbórea apresentou Índice de Diversidade de Shannon estimado em 1,86, sendo que as espécies com os maiores valores de importância foram Prosopis nigra (25,86%), Aspidosperma quebracho-blanco (24,57%), Prosopis affinis (24,30%) e Vachellia caven (10,51%), representando 85,26% do total. A vegetação arbórea apresenta dois estratos bem definidos, o inferior com 93,3% das árvores e o superior com apenas 6,7% do total de árvores amostradas. Neste a espécie Aspidosperma quebracho-blanco predomina com 70,0% das árvores. Com relação ao padrão de distribuição espacial das espécies, Aspidosperma quebracho-blanco apresentou tendência ao agrupamento, de acordo com o Índice de Payandeh, enquanto que as demais espécies apresentaram-se agrupadas. Aspidosperma quebracho-blanco e Prosopis nigra tendem a ocorrer associadas, enquanto Prosopis affinis e Vachellia caven formam grupos individuais. A associação estudada constitui-se de uma formação de espécies única no Brasil, apresentando questão de raridade em termos de composição de espécies e estrutura.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1332010.5902/1980509813320Ciência Florestal; Vol. 24 No. 1 (2014); 23-36Ciência Florestal; v. 24 n. 1 (2014); 23-361980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13320/pdfWatzlawick, Luciano FarinhaLonghi, Solon JonasSchneider, Paulo RenatoFinger, César Augusto Guimarãesinfo:eu-repo/semantics/openAccess2017-04-13T17:24:07Zoai:ojs.pkp.sfu.ca:article/13320Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T17:24:07Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
