Asian invasive algae causes unprecedented impact on Spanish coasts

The invasive Asian algae, Rugulopteryx okamurae, is causing unprecedented environmental and socioeconomic impacts along the Spanish coast, according to biologist María Altamirano from the University of Málaga.

Since its first detection in 2016 near the Strait of Gibraltar, the species has adapted successfully to its new habitat. Altamirano notes that while there is currently insufficient money or knowledge to completely eradicate the algae, its spread can be slowed through prevention, education, and the preservation of reference ecosystems.

The algae is a benthic species that displaces local populations, specifically threatening Posidonia meadows. In areas such as the coast of Granada, the invasion has drastically reduced native biodiversity and altered entire ecosystems.
