En este estudio evaluamos el uso de árboles para la nidificación por parte de aves que nidifican en cavidades de árboles, en la ecorregión del Espinal, Argentina. Analizamos datos de 264 nidos de aves usuarias de cavidades de árboles (114 nidos de carpinteros y 150 nidos de usuarios secundarios) encontrados en un periodo de 49 años (1970–2019), en un paisaje fragmentado. Los principales resultados mostraron que este grupo de aves hacen un mayor uso para nidificar de árboles nativos, como Chañar (Geoffroea decorticans) y Algarrobo (Prosopis alba), tanto vivos como muertos en pie, aunque también se registró el uso de árboles exóticos. Además, las aves usuarias secundarias mostraron un mayor uso proporcional de cavidades generadas por descomposición. Estos hallazgos resaltan la importancia de retener en el paisaje árboles nativos, vivos y muertos en pie, como elementos clave para la conservación de la avifauna en paisajes fragmentados.
