摘要：Charcoal analysis results from two megalithic monuments, situated in
north-eastern Portugal, arepresented. The abundance of heathers, light demanding
plants, is particularly striking. This contrastswith local present-day
vegetation, and testifies to the existence of open areas, devoid of an
importantarboreal cover. The identification of Pinus tipo sylvestris and Taxus
baccata, nearly extinct in Portugal,is also noted.
