Abstract

PRADO, Darién E; FRANCESCHI, Eduardo A  and  BIANCHI, Marta B. El bosque del escarpe occidental del rio Parana (Argentina): composicion floristica y estructura. Acta Bot. Bras. [online]. 1989, vol.3, n.2, suppl.1, pp.99-108. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33061989000300010.

The western limit of the alluvial plains of the river Parana in Argentina presents a pronounced scarp, above the level of floodings. The vegetation, a semideciduos subtropical forest of Amazonian origin, was analyzed using the point-centred quarter method. The parameters relative frequency, relative density, relative dominance and importance value index for each species are provided, together with a brief structural description. The floristic composition is compared with similar forests elsewhere in Argentina and Brazil.

Keywords : bosque subtropical; método de cuadrantes; rio Paraná; valor de importancia.
