| description | Alien invasive woody species (AIWE) in mountain systems usually have high hydric demand and their rates of propagule production are generally elevated. The suppression of AIWE individuals through girdling should reduce propagule input, lowering their expansion rates and improving the conditions for native flora competition. The objective of this work was to evaluate the girdling efficiency and the optimal cutting depth over Morus alba L. and Melia azedarach L. mortality. With chainsaw, one or two girdles were made over the main stem in mature individuals of the mentioned species, and after two years, the survival and vigor of the treated individuals were evaluated. For both species the optimal cutting radio was defined through a percentage of the stem diameter: cutting critical threshold varied between 11 and 13 % of the stem diameter. These values assure for M. alba and M. azederach a treatment efficiency higher than 40 %. The single girdling is the most convenient treatment because of its efficiency and because it is cheaper than double girdling. |

Las especies leñosas exóticas invasoras (ELEI) en sistemas montanos suelen tener alta demanda hídrica y sus tasas de producción de propágulos suelen ser elevadas. La supresión de individuos de ELEI mediante anillado provocaría una reducción en el input de propágulos, disminuyendo su tasa de expansión, y permitiendo mejorar las condiciones de competencia de la flora nativa. El objetivo del presente trabajo fue evaluar la eficiencia del anillado y la profundidad de corte óptima sobre la mortandad de Morus alba L. y Melia azederach L. Con motosierra se realizaron uno o dos anillos sobre el fuste principal de individuos maduros de las especies mencionadas, y al cabo de dos años, se evaluó la sobrevida y el vigor de los individuos tratados. Para ambas especies el radio de corte óptimo se definió a través de un porcentaje del diámetro de fuste: los umbrales críticos variaron entre 11 y 13 % del diámetro. Estos valores aseguran para M. alba y M. azederach una eficiencia de tratamiento superior al 40 %. El anillado simple es el tratamiento más conveniente por su eficacia y por ser más económico con respecto al doble anillado.
