| Reason: This species is endemic to NM with a range extending along the Rio Grande Valley from the Sevilleta to Taos. It can be fairly common at certain locations and uncommon at other locations. It has few threats beyond some localized development. Several of the EOs are old, and there is uncertainty about their continued presence. However, many new EOs have been recorded on iNaturalist. |
