Population justification: The global population size has not been quantified, but the Heinrichia superspecies is described as generally uncommon, being more numerous at the upper end of the altitudinal range (Eaton et al. 2021). Rasmussen (2016) recorded six individuals of H. simplex above 1,600 m in a 10-hour day, and noted that the species was more common above 1,700 m.

Trend justification: In the absence of evidence for significant threats or population declines, the population is suspected to be stable. There is no evidence of forest loss within this species' remote range (Hansen et al. 2013, Global Forest Watch 2023).
