Costa Neto, Salustiano Vilar da Bastos, Maria Nazaré do Carmo Florística Fitossociologia CNPQ::CIENCIAS BIOLOGICAS::BOTANICA The sandbank of Crispim is located between the geographic coordinates 47°40'24" and 47°38'00" WGr.; 00°37'06" and 00°34'42", in the municipality of Marapanim, Pará State. Six plant communities are represented in this restinga: Halophilous, Psammophilous Reptant, Herbaceous Brejo, Stable Dunes, Field between Dunes and Restinga Field. This paper deals only with the first three communities, located between the beach and the mangrove. For the phytosociological studies, the square method (Muller-Dombois & Ellenberg, 1974) was employed for the Halophytic and Herbaceous Brejo Herbaceous communities and the point method (Mantovani & Martins, 1990) for the Reptant Psammophilous community. The Halophytic community, situated just beyond the streambed zone, is represented by 3 species, cited according to their Importance Value Indices (IVI): Sesuvium portulacastrum L. (83.82%), Sporobolus virginicus L. (61.12%) and Iresinevermicularis (55.05%). The Psammophyllous-Reptant, occurs on the first dune cordon, and in this community the species that presented the highest IVI's were: Paspalum vaginatum Sw. (156.90%) and Canavalia rosea (Sw.)DC. (89.97%). The Herbaceous Brejo located on the reverse side of the first dune cordon presents a greater diversity with 12 species distributed in 7 families, where the species with the highest IVI's are Fimbristilys spadicea Vahl. (57.71%), Paspalum vaginatum Sw. (54.25%) and Sporobolus virginicus L. (51.22%). A restinga do Crispim, localiza-se entre as coordenadas geográficas 47°40'24" e 47°38'00" WGr.; 00°37'06" e 00°34'42", no município de Marapanim, Estado do Pará. Nesta restinga estão representadas seis comunidades vegetais: Halófila, Psamófila Reptante, Brejo Herbáceo, Dunas Estáveis, Campo entre Dunas e Campo de Restinga. Este trabalho trata apenas das três primeiras comunidades, situadas entre a praia e o manguezal. Para os estudos fitos sociológicos foram empregados o método do quadrado (Muller-Dombois & Ellenberg, 1974) para as comunidades Halófila e Brejo Herbáceo e o método dos pontos (Mantovani & Martins, 1990) para a comunidade Psamófila Reptante. A comunidade Halófila, situada logo após a zona de estirâncio, está representada por 3 espécies, citadas de acordo com seus Índices de Valor de Importância (IVI): Sesuvium portulacastrum L. (83,82%), Sporobolus virginicus L. (61,12%) e Iresinevermicularis (55,05%). A PsamófilaReptante, ocorre sobre o primeiro cordão dunar, e nesta comunidade as espécies que apresentaram maiores IVI's foram: Paspalum vaginatum Sw. (156,90%) e Canavalia rosea (Sw.)DC. (89,97%). O Brejo Herbáceo localizado no reverso do primeiro cordão dunar, apresenta uma maior diversidade com 12 espécies distribuídas em 7 famílias, onde as espécies de maiores IVI's são Fimbristilys spadicea Vahl. (57,71 %), Paspalum vaginatum Sw. (54,25%) e Sporobolus virginicus L. (51,22%). 2022-11-01T17:22:46Z 2022-11-01 2022-11-01T17:22:46Z 1994-05-13 Resumo COSTA NETO, Salustiano Vilar da; BASTOS, Maria Nazaré do Carmo.
