This group is dedicated to the study of the effects of different treatments, such as controlled (prescribed) burning and/or roller-chopping, compatible with the improvement and restoration of the rangelands of the SW of Buenos Aires province (Monte) and SE of La Pampa province (Caldenal), Argentina. The information collected in this field of research will contribute to designing management strategies to increase production, stability and sustainability of the rangelands in the above-mentioned regions.

Lines of Research

  • Controlled burning and roller-chopping in the SW of Buenos Aires province, Argentina.
  • Controlled burning in the SE of La Pampa province, Argentina.
  • Seed bank in the soil and seed rain in southern Caldenal rangelands, Argentina.
  • Patches of functional woody plants for the restoration of plant diversity in the ecotone Caldenal-Pampa Austral, Argentina.
  • Morphogenetic characteristics and defoliation of perennial grasses.
