Draba hispanica Boiss. subsp. lebrunii P. Monts. is an Iberian endemism exclusive from the Sierra de la Peña (Natural Park Fuentes Carrionas y Fuente CobreMontaña Palentina). Because of its reduced distribution, it was cataloged Vulnerable from Spain but, after the revision for the Red List 2008, resulted Endangered. In Castilla y León region, where it lives is protected (annex II of the Act of Protected Flora 63/2007). It was selected under AFA4, for the project scheme “Detailed cartography of threatened vascular fl ora populations”. A meticulous survey was made all over its distribution area, and we took a census in every known population. Furthermore, we prospected similar habitats resulting in the location of four new populations: Alto de los Llanos, Pico Rabanal, Peña Blanca, and two more in Cueto de la Horca. The total amount of specimens was calculated by means of direct census in every population, which served as a reference to make a global estimation. The threaten category was revised in the bases of all the collected data. It was confi rmed as Endangered, and the criteria were completed. Finally, with all sampled data we made a detailed mapping of every population following the methodology proposed in this stage of AFA. The occupation area and extension of presence were calculated. Some determining factors were evaluated for modeling the potential occupation area. All locations with similar features outside Sierra de Peña were dismissed, after our visit in order to complete its extension of presence.
