In the outline of Portugal’s scenery there is a long-lost past and an uncertain future. Captured forever in the black-and-white memory of old photographs, we can find many healthy-looking specimens of palm trees, which used to be a rich element in the botanical heritage of the capital. Many of these have since fallen victim to town planning, while others, of course, will have met a natural end.
The real disaster, however, began in 2007 with the detection of an infestation of palm weevils, which had already decimated numerous Canary Island date palms (Phoenix canariensis), some of them centuries old. The weevil is insatiable and has already been detected in date palms (Phoenix dactylifera) and fan palms (Washingtonia filifera and Washingtonia robusta), among others.
What does the future hold for these species?
