Conservation status and protection measures for Draba hispanica Boiss. subsp. lebrunii P. Monts., endemic to the Altocarrionés subsector (Castile and Leon, Spain)

Abstract Draba hispanica a subsp. lebrunii is an endemic plant restricted to a small area of the south—western part of the Nature Park and SCI called “Fuentes Carrionas and Fuente Cobre-Montaña Palentina” in the Castile and Leon Region of Spain, included in several regional and national protection catalogues. This paper provides a demographic study of the currently known populations, with the aim of reviewing the conservation status of the taxon in accordance with IUCN criteria, as well as detecting risk factors and providing appropriate management measures to guarantee survival of the taxon. Furthermore, the creation of a Micro—Reserve for Flora is proposed, as a specially protected area in the zone where the most abundant and best preserved population is located. Precise locations for all the previously known sites and others are provided through labelling by means of GPS technology. The current situation of the populations and changes in them are also analysed.
