ASTRAGALUS ENDOPTERUS (FABACEAE), A SPECIES PURPORTED AS EXTINCT, FOUND IN NORTHERN ARIZONA, U.S.A
2024
Overview
Astragalus endopterus (Barneby) Barneby, listed as an extinct species in a recent Conservation Biology paper (Knapp et al. 2021) was found in abundance after three hours of targeted searching. Continued searches revealed thousands of plants. Our work has doubled the known range of the species. Astragalus endopterus seems to mostly occur on sheetwash deposits composed of particles derived mostly from windblown sands along with a component of clay probably derived from the Chinle Formation. We have no indications that the species may have been in decline or was ever on the verge of extinction.
Astragalus endopterus, catalogado como especie extinta en un artículo reciente de Conservation Biology (Knapp et al. 2021), se encontró en abundancia después de tres horas de búsqueda especifica. Las búsquedas continuas revelaron miles de plantas. Nuestro trabajo ha duplicado el rango conocido de la especie. Astragalus endopterus parece ocurrir principalmente en depósitos de láminas compuestos de partículas derivadas principalmente de arenas arrastradas por el viento junto con un componente de arcilla probablemente derivado de la Formación Chinle. No tenemos evidencia que indique que pudo haber estado en declive o al borde de la extinción.
