The conservation status of Scaled Ground-Cuckoo is very poorly known. The species generally is considered to be rare and of high sensitivity. Parker et al. (1996) rated its conservation priority as medium.
Previously, Scaled Ground-Cuckoo had an IUCN Red List conservation status of Near-Threatened (Collar et al. 1992), a status that lasted at least until 2011 (BirdLife International, as cited in Erritzøe et al. 2012). Scaled Ground-Cuckoo no longer is recognized as a species by BirdLife International (del Hoyo and Collar 2014), but instead is classified as a subspecies of Rufous-vented Ground-Cuckoo (Neomorphus geoffroyi), and so does not have an independent IUCN Red List consevation assessment. On the other hand, although Rufous-vented Ground-Cuckoo is widely distributed, its conservation status is assessed as Vulnerable (BirdLife International 2018). Furthermore, it has been predicted that within three generations (13 years) 23.0-25.7% of suitable habitat will be lost to deforestation (Soares-Filho et al. 2006) resulting in an estimated population decline of 30-49% within that time (BirdLife International 2018a).
The conservation status of Scaled Ground-Cuckoo is listed as Vulnerable in Brazil by the Ministério de Estado do Meio Ambiente (MMA 2014).
Alho et al. (2015) suggested that Scaled Ground-Cuckoo could be a good indicator species of habitat quality in freshwater and associated ecosystems in the Amazon basin.
