In the Pampa ecoregion of South America,the intensification of agriculture has led to the almosttotal replacement of pristine vegetation by agroecosystems.This has caused a great loss of biodiversity and adecline of bird assemblages. We monitored birds in DosHermanas Wildlife Reserve, an integrated ecosystembasedmanagement area in preserved natural salinewetland relicts (grasslands and shrublands) with a cultivatedsector (sustainable grazing and organic crops).We recorded a total of 170 species, including altitudinalmigrants, Nearctic migrants, migrants of the temperate-tropical and cold-temperate systems, and residents.Seven are globally threatened species and three are exoticspecies. The high diversity of birds recorded at DosHermanas Wildlife Reserve highlights the importanceof this reserve for the conservation of the regional biota.The application of ecosystem-based management allowsthe presence of contrasting vegetation structures withpositive effects on the diversity of bird assemblages inthe Pampa region.
