Ornamental Cenchrus (Poaceae) in Argentina: From cultivated to invasive?

Background and aims. The introduction of alien plant species for ornamental use represents a risk of invasion for ecosystems. Cenchrus advena, C. longisetus and C. setaceus are grass species introduced as ornamentals and highly cultivated in north-central Argentina, although their status in the inva...

description Background and aims. The introduction of alien plant species for ornamental use represents a risk of invasion for ecosystems. Cenchrus advena, C. longisetus and C. setaceus are grass species introduced as ornamentals and highly cultivated in north-central Argentina, although their status in the invasion process is unknown. In this study, the presence of these three species is recorded, and their taxonomy, nomenclature and morphology are updated. In addition, presence maps and a key to differentiate them from congeners, both native and alien, are presented. The status of the invasion is analyzed and management recommendations are discussed. M&M: Herbarium specimens and new wild and cultivated plants were studied, and open access online database information were compiled. Results: We found 158 records of the three species distributed in 11 Argentine provinces, which allowed us to cite C. setaceus for the first time for the Argentine flora. A high proportion of naturalized records of C. setaceus and C. longisetus were found. Both species presented individuals established in disturbed natural environments of Córdoba province, initiating their state of propagation as invasives. Cenchrus advena was only found under cultivation. Conclusions: The invasive behavior of the grasses C. longisetus and C. setaceus found in Córdoba could be replicating in other provinces due to the high level of cultivation and environmental susceptibility. Therefore, it is urgent to stop their cultivation, monitor naturalized and invasive populations and replace their cultivation with native species within the framework of sustainable objectives and current regulations.

Introducción y objetivos: La introducción de plantas exóticas para uso ornamental representa un riesgo de invasión para los ecosistemas. Cenchrus advena, C. longisetus y C. setaceus son gramíneas introducidas como ornamentales y altamente cultivadas en el centro-norte de Argentina, aunque se desconoce su estado en el proceso de invasión. En este trabajo se registra la presencia de estas tres especies, se actualiza su taxonomía, nomenclatura y morfología. Además, se presentan mapas de presencia y una clave para diferenciarlas de sus congéneres, tanto nativas como exóticas. Se analiza el estado de invasión y se discuten recomendaciones de manejo. M&M: Se estudiaron ejemplares de herbario, nuevas poblaciones de plantas cultivadas y naturalizadas y se recopiló información de bases de datos digitales de acceso abierto.  Resultados: Se encontraron 158 registros de las tres especies distribuidos en 11 provincias, que permitieron citar por primera vez a C. setaceus para la Flora Argentina. Se halló una alta proporción de registros naturalizados de C. setaceus y C. longisetus. Ambas especies presentaron individuos establecidos en ambientes naturales disturbados de Córdoba, iniciando su propagación como invasoras. Cenchrus advena fue únicamente hallada bajo cultivo. Conclusiones: El comportamiento invasor de los pastos C. longisetus y C. setaceus hallado en Córdoba podría estar replicándose en otras provincias debido al elevado nivel de cultivo y a la susceptibilidad ambiental. Por ende, es urgente frenar su cultivo, monitorear las poblaciones naturalizadas e invasoras y reemplazar su cultivo por especies nativas en el marco de objetivos sustentables y reglamentaciones vigentes.
