Population justification: The species is rare and local, being absent from large areas of apparently suitable habitat. In 2003, 28 individuals were counted at six known sites (G. Engblom in litt. 2003); given the number of suitable bogs within its range it was suggested that the global population may potentially number as many as 200-1,000 individuals (G. Engblom in litt. 2003), but is probably closer to the lower figure (J. Barrio in litt. 2009; R. E. Gibbons in litt. 2009). During the surveys from 2008 to 2011, 104 bogs were searched yielding 113 individuals at 18 of these (J. Barrio in litt. 2012). Given the number of suitable bogs within its range it is estimated that the global population may number less than 300 individuals, which would include fewer than 250 mature individuals (J. Barrio in litt. 2012; see also SERFOR 2018). The population is thus here placed in the band 50-249 mature individuals.
The subpopulation structure has not been formally investigated. Nevertheless, given its very small range and occasional records of stray individuals far away from suitable habitat (eBird 2021; J. Barrio in litt. 2021), it is tentatively assumed that the species is able to disperse between sites, so that all individuals would belong to the same subpopulation.

Trend justification: The species is precautionarily inferred to be in decline as suitable bogs within the range have been destroyed by mining activities and are being degraded by overgrazing, through the dumping of deposits, and water and peat extraction. Formerly occupied sites have suffered from mining activities, leading to their partial or complete destruction and the local extinction of the species. At undisturbed sites, the species was found to be stable (F. Angulo in litt. 2021). The rate of population decline has not been quantified.
