Population justification: The population is estimated to number 210-268 individuals, roughly equating to 140-180 mature individuals.

Trend justification: This species is suspected to have suffered ongoing declines at a rate of 10-19% over ten years, owing to widespread and continuing habitat loss within its range. On the northwest flanks of Volcán Pichincha, deforestation rates for high-Andean montane forest accelerated in recent years (Santander et al. 2004). In the period 1996-2006, an estimated 7.5% of the forest cover was lost, extrapolated from the period 1996-2001 (Santander et al. 2004, O. Jahn in litt. 2007). In Esmeraldas, 4% of the remnant high-Andean montane forest were cut in the last decade (Cárdenas 2007). Deforestation was probably much more severe on the slopes above the Intag valley, which are outside the Cotacachi-Cayapas Ecological Reserve and geopolitically belong to Imbabura (O. Jahn in litt. 2007). In the future climate change may play a role in further stressing the species and rendering remaining habitat unsuitable (Jahn and Santander 2008).
