Wetlands, such as salt marshes, include little-known but important ecosystems that are sometimes severely invaded by exotic plants. Salt marshes in eastern South America are increasingly impacted by invasions of the African grass <i>Urochloa arrecta</i>. This study investigated the appearance of a population of the mangrove rail <i>Rallus longirostris</i> in areas dominated by <i>U. arrecta</i> and its disappearance with the eradication of this plant. We monitored four areas (54.47 ha) in the Guaratuba Bay estuary in southern Brazil, from 2006 to 2022, two of which contained four patches of <i>U. arrecta</i> as the dominant species. In 2012, we started to eradicate <i>U. arrecta</i> with mechanical management, andWetlands (Wilmington, N.C.)Appearance of a population of the mangrove rail <i>Rallus longirostris</i> (Rallidae) in salt marshes invaded by the exotic tanner grass <i>Urochloa arrecta</i> (Poaceae) and its disappearance after plant management.PMC973519550005063420184047008BL0001_201110682/200520908_201120004_20120740/200711110_20172Melchiori BLSandretti-Silva GBornschein MRTeixeira Lde Morais Guerra BReinert BLfalseAppearance of a population of the mangrove rail <i>Rallus longirostris</i> (Rallidae) in salt marshes invaded by the exotic tanner grass <i>Urochloa arrecta</i> (Poaceae) and its disappearance after plant management.Biological invasions cause species extinction but can also provide benefits.
