PENSIERO, J F  e  BORTOLUZZI, A L. Distribution and limits of the ecoregions of the north-central province of Santa Fe based on the presence of forest types. FAVE. Secc. Cienc. agrar. [online]. 2021, vol.20, n.1, pp.83-98. ISSN 1666-7719.

The limits of the ecoregions of Chaco Húmedo, Chaco Seco and Espinal are proposed for the north centre of the province of Santa Fe. The delimitation was based on GPS points that located the types quebrachales, quebrachales of three quebrachos and mixed forest, together with locations derived from the Native Forest Land Planning. The location of the forests was jointed to 2.5 km long and wide hexagonal cells within a grid that covered the entire area under analysis. With the cells that marked the presence of each forest class their distribution area was estimated by applying the convex envelope algorithm. The boundaries were proposed interpreting the distribution of forest classes along with field information and floristic analysis. The information generated will orient fieldwork to obtain more details of the vegetation in the bordering areas.
