Description complète des menacesTexte détaillé évaluation IUCNExpert
Although the Bolivian Yungas ecoregion has a good coverage of national parks, and this species does occur within the Entre Ríos protected area, habitat loss and general degradation due to human activities persist outside protected areas (Mee 1998, WDPA 2020). 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 within the Bolivian montane dry forests, which are among one of the most threatened ecosystems in the world (Portillo-Quintero and Sánchez-Azofeifa 2009). It 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). The species grows in the department of Tarija, where the human population size increased by 25% between 2012 and 2022 (Instituto Nacional de Estadistica 2022, Google Earth 2023).
