Marbella Battles Invasive Algae Invasion

Marbella is facing significant challenges with invasive seaweed washing ashore, with local authorities removing 374 tons in a single day. This escalating issue threatens the upcoming tourist season and has led to criticism of the Spanish government for not providing adequate assistance.

The invasive Asian algae, Rugulopteryx okamurae, is identified as the cause of these recurring accumulations. Local councillor Diego Lopez expressed frustration, stating that while the council is committed to cleaning the shore, the machinery cannot access the sea for effective removal due to high biomass concentrations.

While municipalities are incurring costs for frequent cleanups, some environmentalists and scientific entities advocate for leaving the seaweed. They propose that these marine plant accumulations act as a natural shield for beaches, preventing sand erosion and should not be considered waste.
