Abstract

Current knowledge of the biology of Picris willkommii and his grade of threat, seem not to be sufficient to ensure longterm persistence of this plant species endemic to the South-Western Iberian Peninsula. In Spain, main populations of the species are narrowly restricted to therophytic grasslands around the town of Ayamonte, by the Guadiana river drainage. Results of the present study indicate that P. willkommii behaves as a very versatile, colonizing species in most of the habitats of their natural range, where it appears to be well suited to the cyclic disturbance dynamics imposed by local, traditional land uses, i.e. extensive rain-fed agriculture. Moreover, it is easy to grow under controlled conditions. Results could be helpful for conservation and population recovery purposes, as recent changes in land use, shifting from agricultural traditional systems to urban expansion or alternative agricultural systems, pose at risk P. willkommii populations due to habitat loss.
