New information about the vegetational history of the Balearic Islands during part of the Holocene derives from the results of a pollen study of a 20-metre-deep core from Cala Galdana on the SW coast of Minorca. The lower part of the pollen diagram at the beginning of the Atlantic Period records significant quantities of pollen of Corylus and also local taxa indicating swamp vegetation. In the middle part, Corylus is greatly reduced, AP percentages decrease appreciably and Olea and Ericaceae reach important values, while Plantago, Poaceae and Cerealia increase significantly. In the upper part, a rise in Chenopodiaceae occurs, during which a slight increase of the arboreal taxa takes place with greater dryness. Most recently, vegetation changes reflect human activity. © 1994, Taylor & Francis Group, LLC. All rights reserved.
