Posidonia is still losing ground, despite growing awareness of the importance of its conservation, private and public actions in its defense, and specific regulations that have been in place for the past seven years. The data confirm that the rate of its destruction has slowed considerably, but, unfortunately, they also show that "we still cannot speak of surface area recovery in absolute terms," laments Núria Marbà, research professor at Imedea (CSIC-UIB) and a specialist in this plant that is essential to the ecosystem.
