I48-R154-article-85272025-08-08T13:52:28Z Notes on the vegetation of the Santafesinian valley of the Paraná river (Argentine Republic) Notas sobre la vegetación del Valle Santafesino del Río Paraná (República Argentina) Franceschi, Eduardo Andrés Lewis, Juan Pablo This paper describes the plant communities found in the Paraná River valley. Several islands and parts of the floodplain of the Paraná River within the Province of Santa Fe (Argentina) were explored. The vegetation in this area is so complex that it is not possible to describe all communities in detail, but those that can be defined are referred to as noda. For descriptive purposes, they were divided into three main physiognomic groups. Among the arboreal communities, the most evolved noda are the Forestum nigrum, Forestum insularis, and Forestum candicans (the latter lying outside the study area). Variants of these and other related noda include the Cathormietum, Sapietum, and Erythrinetum. The less evolved noda are the willow forest (Salicetum), with two variants, and the Tessarietum. Finally, there is a more xerophytic nodum, the mimosa forest or parkland of Acacia caven. Among the shrubby communities, the best-defined noda are the Bambusetum and the Baccharisetum salicifoliae. Several other shrubby and bushy communities are either very heterogeneous or poorly defined. The herbaceous communities include the Eichhornietum, Pistietum, Panicetum elephanthipes, and other floating types; the Polygonetum, Scirpetum, and Cyperetum; the Panicetum prionitis, Eragrosto-Fimbristyletum, and Distichletum. There are also a large number of mixed herbaceous communities and heterogeneous ones that cannot be segregated into definite noda. The distribution of communities around water bodies is discussed, but no attempt is made to describe vegetation dynamics. Este trabajo describe las comunidades vegetales presentes en el valle del río Paraná. Se exploraron varias islas y partes de la llanura de inundación del río Paraná dentro de la Provincia de Santa Fe (Argentina). La vegetación de esta zona es tan compleja que no es posible describir en detalle todas las comunidades, pero aquellas que pueden definirse se denominan noda. Para su descripción, se las dividió en tres grandes grupos fisonómicos. Entre las comunidades arbóreas, los noda más evolucionados son el Forestum nigrum, el Forestum insularis y el Forestum candicans (este último fuera del área de estudio). Existen variantes de estos y otros noda relacionados, como el Cathormietum, el Sapietum y el Erythrinetum. Los noda menos evolucionados son el bosque de sauces (Salicetum), con dos variantes, y el Tessarietum. Finalmente, existe un nodum más xerofítico: el bosque o parque de mimosa (Acacia caven). Entre las comunidades arbustivas, los noda mejor definidos son el Bambusetum y el Baccharisetum salicifoliae. Varias otras comunidades arbustivas y de matorrales son muy heterogéneas o están pobremente definidas. Las comunidades herbáceas incluyen el Eichhornietum, el Pistietum, el Panicetum elephanthipes y otras de tipo flotante; el Polygonetum, el Scirpetum y el Cyperetum; el Panicetum prionitis, el Eragrosto-Fimbristyletum y el Distichletum. También existe un gran número de comunidades herbáceas mixtas y heterogéneas que no pueden ser segregadas en noda definidos. Se analiza la distribución de las comunidades alrededor de los cuerpos de agua, pero no se intenta describir la dinámica de la vegetación.

This paper describes the plant communities found in the Paraná River valley. Several islands and parts of the floodplain of the Paraná River within the Province of Santa Fe (Argentina) were explored. The vegetation in this area is so complex that it is not possible to describe all communities in detail, but those that can be defined are referred to as noda. For descriptive purposes, they were divided into three main physiognomic groups.
Among the arboreal communities, the most evolved noda are the Forestum nigrum, Forestum insularis, and Forestum candicans (the latter lying outside the study area). Variants of these and other related noda include the Cathormietum, Sapietum, and Erythrinetum. The less evolved noda are the willow forest (Salicetum), with two variants, and the Tessarietum. Finally, there is a more xerophytic nodum, the mimosa forest or parkland of Acacia caven.
Among the shrubby communities, the best-defined noda are the Bambusetum and the Baccharisetum salicifoliae. Several other shrubby and bushy communities are either very heterogeneous or poorly defined.
The herbaceous communities include the Eichhornietum, Pistietum, Panicetum elephanthipes, and other floating types; the Polygonetum, Scirpetum, and Cyperetum; the Panicetum prionitis, Eragrosto-Fimbristyletum, and Distichletum. There are also a large number of mixed herbaceous communities and heterogeneous ones that cannot be segregated into definite noda.
The distribution of communities around water bodies is discussed, but no attempt is made to describe vegetation dynamics. |
