Identification and assessment of the crop wild relatives of Spain that require most urgent conservation actions
Crop Wild Relatives (CWR) are receiving significant attention over the last decades. Numerous conservation plans and guidelines to better manage these resources have been developed lately at both national and international levels. In this sense, Spain is following a similar path to that followed by other countries and has included CWR in the National Strategy for Plant Conservation of Spain and invested in scientific projects dealing with their conservation.In this work, we present a preliminary assessment of the conservation status (both in situ and ex situ) of the Spanish CWR that are in a most urgent need of conservation. Crossability to crops, endemicity, threat status according to IUCN standards and high-quality georeferenced occurrence data were the criteria applied to select the target species, generating a list of 47 CWR species. Eleven of them, classified as Critically Endangered or Endangered by IUCN criteria are not, and should be, included included in the National Catalogue of Threatened Species of Spain; however 35 of them are included in at least one autonomous catalogue. Seventy-five per cent of the species are represented in protected areas, but if a minimum of five populations inside protected areas is sought the representation decreases to a 37%. The preliminary assessment of ex situ conservation shows that a high percentage of the species (81%) has at least one accession in national or international germplasm banks. However, additional studies are needed to determine if the accessions included in germplasm banks provide an adequate representation of the genetic variability of the species.
En los últimos años se están desarrollando numerosos planes y guías de conservación para Parientes Silvestres de Cultivos (PSC), debido al interés que estas especies están despertando. En este sentido, España se ha sumado a las últimas tendencias en conservación de PSC, por ejemplo, incluyéndolos en la Estrategia Nacional de Conservación Vegetal o invirtiendo en proyectos de investigación que buscan su conservación.En este trabajo se presenta una evaluación preliminar sobre el estado de conservación (tanto in situ como ex situ) de los PSC en España que se encuentran en una necesidad más urgente de conservación. Como criterios para seleccionar especies se ha tenido en cuenta su potencial de cruzamiento con cultivos, endemicidad, grado de amenaza de acuerdo a los criterios de la UICN y la disponibilidad datos corológicos de alta calidad de georreferenciación, generándose una lista de 47 especies. Se comprobó la presencia de estas especies en el Catálogo Nacional de Especies Amenazadas de España y en todos los catálogos autonómicos, encontrando que 11 de ellas clasificadas como en Peligro Crítico y en Peligro de acuerdo a los criterios de la UICN no están recogidas en el catálogo nacional; además, 35 de ellas están incluidas en al menos un catálogo autonómico. El 75% de las especies se encuentran representadas en áreas protegidas, sin embargo, si se establece un mínimo de cinco poblaciones este porcentaje baja hasta el 37%. La evaluación ex situ preliminar muestra un alto porcentaje de especies representadas en bancos de germoplasma nacionales o internacionales (81%). No obstante, aún es necesario profundizar en la evaluación del estado de conservación ex situ de estas especies y determinar si su diversidad genética está representada de manera adecuada en los bancos de germoplasma.
