Description complète des menacesTexte détaillé évaluation IUCNExpert
This species occurs in the Bolivian Yungas and the Southern Yungas ecoregions. Although the ecoregion has a good coverage of national parks, habitat loss and general degradation due to human activities persist (Mee 1998). Habitat is burned for growing cash crops, and this has increased, along with logging, due to intensified road-building (Collar et al. 1992). The species also occurs in the Bolivian montane dry forests ecoregion, which are among one of the most threatened ecosystems in the world (Portillo-Quintero and Sánchez-Azofeifa 2009). The ecoregion contains large areas of degraded land, and the region is heavily impacted by urban expansion and the associated conversion to agriculture (Fjeldså and Mayer 1996).

This species has been recorded within the protected areas of Rio Grande Valles Crucenos and the Jardín de Cactáceas de Bolivia (WDPA 2020). However, the species remains threatened here (M. Martinez pers. comm. 2024). The seeds of this species are not currently held by any seed bank (Genesys 2023). However, there are 33 records of ex situ collections worldwide (BGCI 2023).
