The Natural Park of the Llevant Peninsula organizes a free outing on August 29 to learn how to detect species such as Halophila stipulacea.
Next Saturday, August 29, the Natural Park of the Llevant Peninsula has scheduled a free activity in Cala Rajada to address a growing problem: the spread of invasive marine algae in the Mediterranean. The event, from 10:00 to 13:00, will start from the Cap Vermell Centre in Cala Rajada and will be led by botanist Lluís Salom Vicens, associated with the BOTLAND group at the University of the Balearic Islands (UIB).
During the day, attendees will discover how these species affect the ecosystems of the Balearics and why it is so difficult to manage them. Real examples will be presented, such as Asparagopsis taxiformis and the recent arrival of Halophila stipulacea, a tropical plant that has already been detected in the waters of the archipelago and is particularly concerning to scientists.
The activity includes a practical part: participants will learn to identify these algae and collaborate with the citizen science project Biodibal, which allows anyone to record sightings. The day will conclude with a trip to the coast to locate possible areas with the presence of these invasive species.
Participation is free, but prior registration is required through the form provided by the natural park. The activity is recommended for the general public aged 10 and over, and it is advised to bring water, snacks, a hat, and comfortable shoes for walking. The organizers remind that the entry of domestic animals is not allowed.
This initiative is part of the August activity agenda of the protected area, which aims to involve residents and visitors in the conservation of the coastline of the Llevant region. Interested parties can obtain more information and download the complete program on the Capdepera Town Hall website.
