A recent study has identified a total of 231 invasive marine species in the waters of Portugal. This figure represents an increase of 98 species compared to what was recorded ten years ago, which amounts to a growth of 75%.

The rate of new introductions of invasive species in Portuguese waters has been classified as 'very high'. This data highlights concerns regarding marine biodiversity and the potential impacts on local ecosystems.

The study's data provide crucial insights into the dynamics of invasive species, which can negatively affect native species and marine habitats. Continuous identification and monitoring of these species will be essential for the preservation of ecosystems.

Authorities and conservation organizations should consider this information a priority in developing policies and conservation strategies, given the significant increase in the rate of invasive species over recent decades.
