HILGERT, Norma I. et al. Vegetation of the saladillo area (province of santa fe) in the south of the chaco, argentina. INCI [online]. 2003, vol.28, n.9, pp.512-520. ISSN 0378-1844.

The vegetation of the Saladillo area of the province of Santa Fe, Argentina, is analyzed. The region is located in the south of the Santa Fe Chaco, between the Toba and Saladillo rivers, at the west of the Paraná River valley. Climate is humid to sub-humid and warm to temperate. There are three types of forests, the "espinillares" of Acacia caven, the "algarrobales" of Prosopis spp. and the "quebrachales" of Schinopsis balansae, distributed following a geographical gradient. The number of woody species increases northwards, and stratification and structure becomes more complex in that direction. The most important herbaceous plant communities are tall grasslands or savannas of Spartina argentinensis and Panicum prioniti, along with other less important grasslands. In lower areas flooded for long periods or the whole year, there are rushes of Schoenoplectus californicus, cattails of Typha domingensis and several hygrophilous meadows. The communities are distributed following a soil moisture and salinity gradient. The area can be considered as an impoverished Chaco region with a strong influence of the Paraná River.
