Introduction Paraguay is located in the centre of the South American continent, between 18°28′ and 27°30′ south latitude and 54°19′ and 62°38′ west longitude (De Egea et al. 2012, Peña-Chocarro and De Egea 2018). The Paraguay River divides Paraguay into two large geographic regions: the eastern region, characterised by mesophilic formations, and the western region, or Chaco, characterised by mainly xerophytic formations (Spichiger et al. 2011).
