Abstract

Portuguese crowberry (Corema album (L.) D. Don) is a shrub considered endemic to the Atlantic coastal dunes of the Iberian Peninsula. For many reasons, among which the most prominent are habitat loss and competition from invasive species, but possibly also due to overexploitation, the survival of several of its populations is now compromised. By promoting the identification of its archaeobotanical remains and gathering information about its past uses, the current need for conservation is emphasized. The plant has been exploited for its berries since at least the Early Neolithic and the species features in a number of historical written sources. Archaeological sites located within its current natural distribution area have yielded relatively abundant archaeobotanical finds. This evidence suggests that its distribution area was much larger in the past and has decreased rapidly in recent decades. Its archaeological importance may be misrepresented due to issues with identification, particularly outside its current distribution area. It is hoped that this paper will contribute to a higher identification rate of archaeobotanical remains of this plant, eventually leading to a more thorough recognition of its past importance and contributing to its present conservation.
