Background and aims: Acacia melanoxylon (Australian blackwood) is an invasive alien species that expands on remnants of native communities of the Paititi Private Nature Reserve (Tandilia System, Argentina). The objective of this work was to design an adaptive management plan to contain the spread of this species.
M&M: We quantified the area invaded between 2003 and 2020 and described the population structure of A. melanoxylon in sampling plots with two different invasion timeframes: recent and old invaded sites. We identified negative, positive, and neutral impacts of the invasion and proposed impact management strategies.
Results: We detected a spread of 23.3 ha over native environments in 17 years. Although the basal area of individuals was similar between recent and old invaded sites (18.3 m2 ha-1), the density was higher in recent invaded sites as compared to old invaded sites (3205 and 965 individuals ha-1, respectively). We identified 26 impacts, 73% ecological and negative, and formulated a seven-step management proposal.
Conclusions: Our results allow us to begin understanding the impacts and dynamics of the invasion of A. melanoxylon and plan on its management. Although we use the reserve as a case study, the management plan can have a projection to other invaded areas of Tandilia. To achieve an efficient and effective invasion management, conservation and recovery of native environments, it will be necessary to conduct collaborative strategies among the different stakeholders involved in the management process. |

Introducción y objetivos: Acacia melanoxylon (acacia australiana) es una especie exótica invasora que se encuentra en expansión sobre relictos de comunidades nativas de la Reserva Natural Privada Paititi (Sistema de Tandilia, Argentina). El objetivo de este trabajo fue diseñar un plan de manejo adaptativo para contener el avance de esta especie. M&M: Se cuantificó el área invadida entre 2003 y 2020 y se describió la estructura de poblaciones de A. melanoxylon en parcelas con dos diferentes tiempos de invasión: reciente y antigua. Se identificaron impactos negativos, positivos y neutros de la invasión y se propusieron estrategias para la gestión de impactos. Resultados: Se detectó una invasión de 23,3 ha sobre los ambientes nativos en 17 años. El área basal de los individuos fue similar entre los sitios invadidos con diferente tiempo transcurrido (18,3 m2 ha-1). Sin embargo, la densidad fue mayor en sitios recientemente invadidos que en sitios con invasión antigua (3205 y 965 individuos ha-1, respectivamente). Se identificaron 26 impactos, siendo el 73% ecológicos y negativos, y se formuló una propuesta de gestión de siete pasos. Conclusiones: Estos resultados permiten comenzar a comprender la dinámica de la invasión para planificar el manejo de A. melanoxylon. Aunque se utilizó la reserva como caso de estudio, el plan de manejo puede proyectarse a otras áreas invadidas de Tandilia. El logro eficaz y efectivo del manejo de la invasión, conservación y recuperación de los ambientes nativos requerirá de ejecutar estrategias colaborativas entre los actores sociales implicados en el proceso de manejo.
