Background and aims: The restoration of forests in areas degraded by anthropic activities is an important practice in the management of mountain systems. Much research is yet needed on methods to reduce effects of herbivores and harsh environments on the establishment of planted tree saplings. Here, we evaluate the effectiveness of a physical protection using polyvinyl chloride (PVC) cylinders in the plantation of two native tree species in the mountains of Central Argentina, in an area with the presence of leaf-cutting ants.
M&M: The study species were escallonia (Escallonia cordobensis) and maitén (Maytenus boaria). The plantation site was at 1840 m asl. We used 230 seedlings per species, 100 with and 130 without a PVC protection. Outplanting was performed during the wet season in areas with low vegetation. We measured height, survival and herbivory every six months for two years.
Results: For escallonia and maitén, respectively, physical protections increased biannual survival in 24 and 26%, increased height in 7.3 and 12.6 cm, and reduced herbivory by leaf-cutting ants in 30 and 51% as compared to non-protected saplings.
Conclusions: The favorable effects of PVC protections on survival and growth could be due to the decrease in herbivory caused by leaf-cutting ants and also due to the protection against harsh abiotic conditions. We advocate for longer term studies which also aim at understanding the mechanisms underlying the improvement in seedling establishment. |

Introducción y objetivos: La restauración de bosques en sitios degradados por actividades antrópicas es una actividad importante en el manejo de sistemas montanos. Aún hace falta investigación tendiente a reducir el efecto de la herbivoría y de las condiciones ambientales hostiles sobre el establecimiento de plantines de árboles. Nos propusimos evaluar la efectividad de una protección física usando tubos de policloruro de vinilo (PVC) en la plantación de dos especies arbóreas nativas de las Sierras de Córdoba (Argentina) en un área con presencia de hormigas cortadoras. M&M: Las especies de estudio fueron escallonia (Escallonia cordobensis) y maitén (Maytenus boaria). El área de plantación estuvo a 1840 m snm. Usamos 230 plantines por especie, 100 de ellos con y 130 sin protección de PVC. Fueron plantadas durante la estación húmeda en sitios con vegetación baja. Medimos semestralmente y por dos años la altura, la supervivencia y los daños por herbivoría. Resultados: Para escallonia y maitén, respectivamente, la protección aumentó la supervivencia a los dos años en 24 y 26%, aumentó la altura en 7,3 y 12,6 cm, y redujo la herbivoría por hormigas cortadoras en 30 y 51% en comparación con los plantines sin protección. Conclusiones: El efecto favorable de las protecciones en la supervivencia y crecimiento podría deberse conjuntamente a la disminución de la herbivoría por hormigas cortadoras y al resguardo contra las condiciones abióticas desfavorables. Recomendamos estudios de más años, y tendientes a entender los mecanismos que subyacen a la mejora en el establecimiento de los plantines.
