Rareza, estatus de conservación y sus determinantes ecológicos. Revisión de su aplicación a escala regional

Abstract

En este trabajo se efectúa una revisión crítica sobre la rareza ecológica, las categorías de amenaza de las especies y la definición de su estatus de conservación. En la aplicación de los criterios cuantitativos para establecer categorías de amenaza existen numerosos problemas lógicos asociados con la conservación de la biodiversidad, biológicos relacionados con la historia natural de las especies y metodológicos vinculados a aspectos de diseño científico y fiabilidad de los datos. No sería recomendable crear categorías que definan el estatus de amenaza a escalas nacional o regional cuando los datos utilizados sean pura especulación. Esto es especialmente preocupante cuando la rareza a escala regional venga motivada por aspectos puramente biogeográficos (e.g., poblaciones en bordes de distribución). Se proponen alternativas para la aplicación de criterios definitorios de estatus de conservación a escala regional (p.e., nacional o comunidades autónomas).
