Macaronesia Faces Unprecedented Plant Extinctions Due to Tourism Boom

A comprehensive study reveals alarming plant extinction rates in Macaronesia (Canary Islands, Azores, Madeira, and Cape Verde), exceeding natural rates tenfold. Led by IPNA-CSIC, the research identifies coastal areas as recent extinction hotspots, linked to the tourism boom since the 1960s. The study documented 168 disappearance events, including 13 global extinctions. Factors increasing extinction risk include invasive herbivores, human population growth, and island age. Endemic, woody plants pollinated or dispersed by animals are particularly vulnerable. Researchers urge for stronger protection of vulnerable species, improved monitoring, updated red lists, and sustainable tourism practices. Reintroduction of extinct species and potentially de-extinction efforts are also proposed for ecosystem restoration.
