Distribution of native and non-native plants along elevation gradients on mountain trails in the Mendoza Andes, Argentina

Background and aims: Climate change, together with livestock and increasing tourism use, favors the dispersal of non-native plants, threatening the conservation of high Andean ecosystems. We aim to assess the distribution patterns of native and non-native species along recreational trails. M&amp...

description Background and aims: Climate change, together with livestock and increasing tourism use, favors the dispersal of non-native plants, threatening the conservation of high Andean ecosystems. We aim to assess the distribution patterns of native and non-native species along recreational trails. M&M: We implemented the MIREN T- Trails protocol in six trails (2400-3600 m asl) in two protected areas of the central Andes of Mendoza, located in the Cordilleras Frontal and Principal. Results: We found 180 native and 41 non-native. Native richness peaked at intermediate elevations, while non-native richness decreased with elevation. The Cordillera Frontal had more native richness than the Cordillera Principal (114 vs. 71 native, respectively), but regional richness of exotics was lower in the Cordillera Frontal (20 vs. 28 exotic, respectively). The non-native richness per plot was higher in the Cordillera Frontal than in the Cordillera Principal. In turn, the altitudinal distribution range of non-native was greater in the Cordillera Frontal, showing that exotic are more widely distributed in more humid sites of the arid Andes. Two abundant non-natives, Taraxacum officinale and Cerastium arvense, were present along the entire surveyed gradient in the Cordillera Frontal, reaching 3600 m asl. We found seven non-natives not previously cited for the region. Conclusions: The new records found extend the known distribution ranges of some non-native species. Our results show that although the number of non-native species was similar near and far from trails, five species were present only at trail edges, suggesting that trails favor invasion processes.

Introducción y objetivos: El cambio climático, el ganado y el creciente uso turístico favorecen la dispersión de plantas exóticas, amenazando la conservación de los ecosistemas altoandinos. Estudiamos los patrones de distribución de plantas nativas y exóticas en senderos recreativos de montaña. M&M: Implementamos el protocolo MIREN en seis senderos (2400-3600 m s.n.m.) en dos áreas protegidas de los Andes centrales de Mendoza en las Cordilleras Frontal y Principal. Resultados: Encontramos 180 especies nativas y 41 exóticas. La riqueza de especies nativas fue máxima a elevaciones intermedias, mientras que la riqueza de exóticas disminuyó con la elevación. La riqueza regional de nativas fue mayor en la Cordillera Frontal que en la Principal (114 versus 71 nativas, respectivamente) mientras que la riqueza regional de exóticas fue menor en la Frontal que en la Principal (20 versus 28 exóticas, respectivamente). La riqueza de exóticas por parcela fue mayor en la Cordillera Frontal que en la Principal. El rango de distribución altitudinal de exóticas fue mayor en la Cordillera Frontal. Dos exóticas abundantes, Taraxacum officinale y Cerastium arvense, estuvieron a lo largo de todo el gradiente en la Cordillera Frontal, alcanzando los 3600 m s.n.m. Encontramos siete exóticas no citadas anteriormente. Conclusiones: Los nuevos registros amplían los rangos de distribución conocidos para algunas especies exóticas. A pesar de que el número de especies exóticas fue similar cerca y lejos de los senderos, cinco especies sólo estuvieron en los bordes de los mismos, lo que sugiere que los senderos favorecen los procesos de invasión.
