Análisis florístico unidades de vegetación Región Chaqueña Villa Escolar. Floristic analysis vegetation units Chaco Region Villa Escolar Contribution to the floristic knowledge of the Eastern Chaco, Formosa province, Argentina. The southeastern of Formosa province integrates part of the Oriental Chaco, characterized by a great environmental heterogeneity, where woody components and grassland are mixed. This complex characteristic is linked to the forms of the landscape, which it is the result of alluvial dynamics during the Pleistocene-Holocene and of the migration of fluvial belts of principal rivers. In this contribution, the floristic composition of different communities of Laishi (Formosa) is analyzed, in order to establish the composition and variability of its elements. For this, species collected near the town, herbarium and bibliography data showed the presence of 625 species, where Asteraceae, Poaceae and Fabaceae families were predominated. There are different vegetation units: forests, palms, shrubs, mesophyte and hydrophyte grasslands, and marshes, where forests and hydrophyte grasslands are dominated. Spatial distribution of the vegetation was analyzed according to the topographic height preference, especially the distribution of tree communities. This information was obtained from satellite images. In addition, Amazon forest components (Yungas and Paranaense) among Chaquenian species were found. El sureste de la provincia de Formosa integra parte de la Región del Chaco Oriental, caracterizada por una gran heterogeneidad ambiental, donde se mezclan componentes leñosos y pastizales. Esta característica compleja está vinculada con las formas del paisaje, la cual, es el resultado de la dinámica aluvional durante el Pleistoceno-Holoceno y de la migración de los cinturones fluviales de los principales ríos. En esta contribución se analiza la composición florística de las comunidades dentro del Departamento de Laishi (Formosa), con la finalidad de establecer la composición y variabilidad de sus elementos. A través datos de campo, de herbario y bibliográficos se encontraron 625 especies, donde predominan las familias de Asteraceae, Poaceae y Fabaceae. Se establecieron las siguientes unidades de vegetación: selvas, bosques, palmares, arbustales, pastizales mesófilos, pastizales hidrófilos y esteros/lagunas, donde predominaron las selvas y pastizales hidrófilos. Sobre la información obtenida de imágenes satelitales, se analizó la distribución espacial de la vegetación según la altura topográfica de preferencia, resaltando la presencia de las comunidades arbóreas. Las especies chaqueñas fueron encontradas conviviendo en muchos casos con componentes selváticos amazónicos (Yungas y Paranaense).

Contribution to the floristic knowledge of the Eastern Chaco, Formosa province, Argentina. The southeastern of Formosa province integrates part of the Oriental Chaco, characterized by a great environmental heterogeneity, where woody components and grassland are mixed.

In this contribution, the floristic composition of different communities of Laishi (Formosa) is analyzed, in order to establish the composition and variability of its elements.
