Short-tailed Antthrush has a very wide geographic range, is fairly common within its habitat, and although the population trend is not quantified, the population is believed to be stable. Consequently the IUCN Red List conservation status of Short-tailed Antthrush is assessed as Least Concern (BirdLife International 2013).
Effects of human activity on populations
Short-tailed Antthrush occupies forest, usually humid montane forest, throughout its range, and so as is true of all species that are restricted to forest, it is vulnerable to habitat degradation or loss. In the short term, however, no threats to this species are identified by BirdLife International (2013).
