Threats [top]

Major Threat(s): Large areas of suitable habitat are remaining. There is some localized habitat loss to general human activities such as collection of wood, logging, and agriculture (crops, livestock etc.). Over harvesting of bromeliads might lead to some localized declines.

Conservation Actions [top]

Conservation Actions: In Peru it is present in several protected areas (Pacaya-Samiria Reserve, Alpahuayo Mishana Reserve). In Colombia it is present in Parque Nacional Natural Amacayacu.
