Beyond Lihué Calel National Park: New records for the rarity Gaillardia Cabrerae covas (Asteraceae)
Until now, Gaillardia cabrerae Covas has been considered an exclusive endemic species of Lihué Calel, a mountain range system in the center-south of La Pampa and the only National Park in the province. In this work, two new presence sites are recorded outside the limits of the protected area. Through an active search in sites with similar geological characteristics to the known distribution site, a population was identified in the Sierras Chicas and another one in the Choique Mahuida Hills, the latter about 95 km southern Lihué Calel National Park. The condition of rarity and the criteria to be taken into account for the categorization of the species are discussed even when its spatial distribution is now resized. The sites in which G. cabrerae develops represent refuges in which many rare species find particularities of the microsite in order to survive. The vulnerability of the species deserves studies that account for its habitat requirements, emphasizing unprotected populations.

Gaillardia cabrerae Covas ha sido considerada hasta el momento especie endémica exclusiva de Lihué Calel, sistema serrano del centro sur de La Pampa y el único Parque Nacional de la provincia. En este trabajo se registran dos nuevos sitios que dan cuenta de la presencia de esta especie por fuera de los límites del área protegida. Mediante búsqueda activa en sitios con características geológicas similares al sitio de distribución conocido, se identificó una población en las Sierras Chicas y otra en las Sierras de Choique Mahuida, esta última alejada a unos 95 km al sur del Parque Nacional Lihué Calel. Se discute sobre la condición de rareza y los criterios a tener en cuenta para la categorización de la especie aun cuando su distribución espacial se encuentra ahora redimensionada. Los sitios en los que G. cabrerae se desarrolla representan refugios en los cuales muchas especies raras encuentran particularidades del micrositio para poder subsistir. La vulnerabilidad de la especie merece la realización de estudios que den cuenta de sus requerimientos de hábitat, poniendo énfasis en las poblaciones no protegidas.
