In the Pampa ecoregion of South America, the intensification of agriculture has led to the almost total replacement of pristine vegetation by agroecosys-tems. This has caused a great loss of biodiversity and a decline of bird assemblages. We monitored birds in Dos Hermanas Wildlife Reserve, an integrated ecosystem-based management area in preserved natural saline wetland relicts (grasslands and shrublands) with a cul-tivated sector (sustainable grazing and organic crops). We recorded a total of 170 species, including altitudinal migrants, Nearctic migrants, migrants of the temper-ate-tropical and cold-temperate systems, and residents. Seven are globally threatened species and three are ex-otic species. The high diversity of birds recorded at Dos Hermanas Wildlife Reserve highlights the importance of this reserve for the conservation of the regional biota. The application of ecosystem-based management allows the presence of contrasting vegetation structures with positive effects on the diversity of bird assemblages in the Pampa region.
