| Résumé : |
On the basis of extensive field studies throughout Greece and of about 19 500 field and literature records extracted from the Flora Hellenica Database, we provide the first survey of wild plant species of traditional agriculture in Greece (hereafter TA species). For each of the 138 taxa, life form, rareness (on national scale), local abundance (habitat occupancy) and regional restrictedness are given. We infer population trends from the record chronology of the taxa in the Flora Hellenica Database, and we assess the Red List status of the arable plants using IUCN criteria. According to current knowledge, two TA species are presumed Extinct in Greece and seven Critically Endangered. Almost half of the species are threatened, including 46 Vulnerable and 15 Endangered taxa. There is a high proportion of locally distributed taxa among Greek TA species. Distribution patterns show a pronounced south–north gradient, and the unique character of the East Aegean arable flora is revealed. Most arable species are annuals (83%). Perennial herbs, mostly bulbous or tuberous plants (geophytes), account for 17%, and a major proportion of the latter must be considered as threatened at different levels. The chronology of decline of certain TA species is reflected by processes of agricultural intensification and regional urbanization. We suggest conservation measures for the unique arable flora of Greece. To reflect the geographical and ecoregional variation, in situ measures should focus on areas with species-rich arable fields in all phytogeographical regions of Greece. |
