Spain has a very rich and dynamic traditional ecological knowledge system that has suffered severe erosion over the last decades. This knowledge has been deeply influenced by a rich and diverse historical heritage that includes many centuries old documents from ancient cultures, some over 2000 years old. Spanish acute useful flora comprises around 3,000 species, most of them autochthonous. A team of more than 70 scientists from more than 30 universities and other research centres are developing the Spanish Inventory of Traditional Knowledge. The inventory includes a database with information from over180 papers. The review of such papers showed that more than 2,300 plant species are used in human and animal food and medicine: 1,681 in human medicine, 1,295 in animal food, 953 in human food and 709 in veterinary medicine. Nearly 14% of the species (313) are shared in the four categories and a very important amount of species are used both for humans and animals: 35% of the species (800) are employed in animal food and medicine, 31% (710) in human food and medicine, 28% (650) in human and veterinary medicine and 27% (624) in animal and human food. This high percentage of overlap between human and animal uses may indicate that the observation of animal behaviour , specially feeding and selfmedication behaviours, might have given clues to humans on how to use food and medicinal plants[Lo1]. It also reinforces the idea that food and medicine represent a continuum not only for humans, but also for animals.
