Population justification: The population size has not been estimated directly. Even in its preferred habitat the species appears to be patchily distributed, not common and hard to find. While Renjifo et al. (2016) suspect a population size of below 10,000 mature individuals, other studies suspect an even lower size of fewer than 1,000 mature individuals (Collar and Salaman 2013). Precautionarily, the population is placed here in the band 250-999 mature individuals, though this requires confirmation. It is moreover suspected that all individuals belong to the same subpopulation.
Trend justification: No population trend data are available for the species. Habitat loss within the range is difficult to quantify, as the loss of páramo habitat may be exacerbated by degradation (Renjifo et al. 2016). It is estimated that 50.4% of the original páramo habitat within the range have been lost; between 2000 and 2011, the rate of loss amounted to 25.5% (Renjifo et al. 2016). Assuming that this is continuing at the same pace into the future and accounting for additional impacts of habitat degradation, habitat may be lost at a rate of 30-49% over ten years.
