Resumo

O presente trabalho foi realizado no Parque Natural Municipal de Santo Ângelo (RS), pertencente à Prefeitura Municipal de Santo Ângelo, com o objetivo de avaliar a composição florística e estrutura fitossociológica da floresta, em uma área de 13 hectares. Para tanto, foram utilizadas 12 parcelas de tamanho 10 x 20 m distribuídas sistematicamente na área, nas quais foram medidos e identificados todos os indivíduos com DAP maior ou igual a 10 cm. Os resultados obtidos foram analisados e processados com o uso do programa FITOANÁLISE, calculando-se os parâmetros fitossociológicos de densidade, dominância, frequência, valor de importância, valor de cobertura, índice de diversidade de Shannon H' e índice de Morisita. Foram encontradas 35 espécies, pertencentes a 30 gêneros e 21 famílias, das quais branquilho ( Sebastiania commersoniana check for this species in other resources (Baill.) L. B. Sm. & Downs), açoita-cavalo ( Luhea divaricata check for this species in other resources Mart), maria-preta ( Diatenopterix sorbifolia check for this species in other resources Radlk) e canela-preta ( Nectandra megapotamica check for this species in other resources Spreng.) foram as que apresentaram maior representatividade nos parâmetros fitossociológicos do componente arbóreo desta floresta. As espécies com maior Valor de Importância (VI) foram açoita-cavalo (Luhea divaricata Mart) com 50,53; branquilho (Sebastiania commersoniana (Baill.) com 46,24; maria-preta (Diatenopterix sorbifolia Radlk) com 26,93; canela-preta (Nectandra megapotamica Spreng.) com 20 e farinha-seca ( Machaerium stipitatum check for this species in other resources Vogel) com 16,64. Já na estrutura vertical da floresta, Luehea divaricata apresentou maiores valores no estrato superior e Sebastiania commersoniana Baill. nos estratos médio e inferior.

Abstract

The present work was performed in the Natural Municipal Park of Santo Ângelo (RS) owned by the City Government of Santo Ângelo, the objective was to evaluate the floristic composition and the phytosociological structure of the forest, in an area with 13 hectares. Twelve units samples of size 10 x 20 m systematically distributed in the area were used , in which these unit samples were measured and identified all individuals with DAP greater than or equal to 10 cm. The results were analyzed and processed with the use of the software FITOANÁLISE, calculating the phytosociological parameters of density, dominance, frequency, value of importance, value of coverage, diversity Shannon H’ index and Morisita index. 35 species were found, belonging to 30 genera and 21 families, of which ( Sebastiania commersoniana check for this species in other resources (Baill.) L. B. Sm. & Downs), açoita-cavalo ( Luhea divaricata check for this species in other resources Mart), maria- preta ( Diatenopterix sorbifolia check for this species in other resources Radlk) e canela preta ( Nectandra megapotamica check for this species in other resources Spreng.) were the ones with greater in phyto-sociological parameters from the tree components of forest. The species with the greatest value of importance (VI) were açoita-cavalo (Luhea divaricata Mart) with 50,53; branquilho (Sebastiania commersoniana Baill.) with 46,24; maria- preta (Diatenopterix sorbifolia Radlk) with 26,93, canela preta (Nectandra megapotamica Spreng.) with 20 and farinha-seca (Machaerium stipitatum Vogel) with 16,64. The forest vertical structure Luhea divaricata showed higher values in the upper stratum and Sebastiania commersoniana Baill in middle and lower strata.
