This species has a moderately small global population which is suspected to be declining moderately rapidly owing to habitat loss and within which all subpopulations are small. It is consequently classified as Near Threatened.
|Previously published Red List assessments:||
|Range Description:||Oreotrochilus adela has a restricted range in the high Andes of La Paz, Cochabamba, Potosí and Chuquisaca, south-west Bolivia (Armonía 1995). There are also reports of breeding birds from Argentina.|

|Population:||The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to 6,700 mature individuals. This requires confirmation.
Trend Justification: The population is suspected to be in decline owing to habitat degradation and destruction.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits arid montane scrub, Polylepis forest and disturbed habitats at 2,550-4,000 m (Fjeldså and Krabbe 1990, Armonía 1995, Parker et al. 1996).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||4.2|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The main threats are heavy grazing by livestock and the uncontrolled use of fire, which combine to prevent Polylepis regeneration, especially where cutting for timber, firewood and charcoal occurs (Fjeldså and Kessler 1996). The change from camelid to sheep and cattle farming, erosion and soil degradation caused by agricultural intensification and afforestation, especially where exotic tree species (e.g. Eucalyptus) are planted (Fjeldså and Kessler 1996), are contributory factors.|
Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Establish adequate protected areas to protect the species's core range. Monitor population at strongholds and search for the species in potentially suitable habitat at new sites. Study its ecology and its ability to persist in degraded and fragmented habitats. Attempt to obtain an accurate estimate of its population size and trends. Quantify extent of habitat losses.
