In recent years, the expansion of invasive alien species has posed a considerable challenge to the protected areas of the Spanish coast. Marbella is particularly faced with the advance of acacia trees, trees that, despite their ornamental appearance, cause serious imbalances in the dune ecosystem. The City Council, together with various organizations, is carrying out an intensive campaign to contain and eradicate these specimens, thus reinforcing its commitment to the local natural heritage.
The acacia trees are among the invasive plant species that have the greatest impact on the native flora in the dune systems of the Costa del Sol. Their rapid proliferation endangers both native plants and the entire protected landscape. Therefore, the management and elimination of regrowth has become a priority within conservation plans.
Removal of acacia trees in the Marbella Dunes Reserve
Over the past few months, there have been cleaning and restoration work at different key points in the Marbella Dunes Ecological Reserve. This operation, carried out with specialized machinery and teams of trained workers, has allowed the removal of more than 13.000 kilos of acacias and other non-native species in enclaves such as El Barronal de la Morena, areas close to pedestrian walkways and dune transition areas.
The use of tracked backhoes, dump trucks, and trucks has made it possible to access difficult terrain and transport plant debris without damaging the environment. In particularly sensitive areas, workers have proceeded manually or with chainsaws, ensuring the minimal disturbance of natural habitats.
The elimination of acacias has been complemented by the removal of reeds and broom in areas such as the Calahonda dune, La Adelfa, and El Alicate. This joint effort, driven by collaboration with environmental associations such as Produnas, seeks to limit the regeneration capacity of invasive species and restore ecological balance.
Importance of controlling invasive species
The presence of acacias in the dunes It not only affects plant biodiversity, but also negatively impacts the fauna, soil, and natural dynamics of the coastal environment. Controlling its regrowth is key to halting its spread and preserving the environment. the environmental value of the ReserveFurthermore, the removal of these species allows native vegetation to regain its space, promotes dune stabilization, and minimizes the risk of forest fires by reducing the load of flammable plant matter.
These efforts are part of a comprehensive conservation plan that encompasses not only the removal of invasive species, but also habitat restoration, environmental education, and the promotion of local volunteerism. The goal is to ensure the long-term sustainability of these natural enclaves, which are essential as a refuge for biodiversity along the coastal strip.
Expansion of citizen protection and collaboration
Given the persistence of the problem and the vulnerability of other neighbouring dune systems, the Marbella Town Hall has recently requested the expansion of the protected area of the Ecological Reserve. The aim is to include enclaves such as Calahonda, El Pinillo and Torre Real, which are also suffering the effects of the acacia invasion and other exotic species.
Collaboration between public administration, environmental experts, and voluntary associations has proven essential in tackling a task of such magnitude. social mobilization and citizen engagement reinforce the effectiveness of on-the-ground interventions and contribute to raising awareness about the importance of protecting natural values.
Acacia removal and control efforts will continue throughout July, with particular emphasis on areas with the greatest number of regrowth. Ecological restoration of the dunes is a meticulous process that requires consistency and coordination to ensure its success.
Progress in the management of invasive acacias represents a step forward in the conservation of Marbella's dune areas, a natural heritage that requires everyone's involvement to ensure its preservation against future threats.
