Conservation

The IUCN Red List conservation status of Castelnau's Antshrike is assessed as Least Concern (BirdLife International 2012). This species has a wide distribution, although the population trend, while not quantified, is believed to be one of decline (BirdLife International 2012).

The relative abundance of Castelnau's Antshrike is assessed as "uncommon to locally fairly common" in Peru (Schulenberg et al. 2007).

Effects of human activity on populations

Human activity has little short-term direct effect on Castelnau's Antshrike, other than the local effects of habitat destruction; this species occupies successional habitats, however, and is tolerant of a low level of human disturbance (Armacost 2004). In the longer term, Castelnau's Antshrike potentially is vulnerable to widespread habitat loss, as might occur through perturbations of the Amazonian hydrological regime stemming from widespread deforestation, dam construction, or global climate change (Armacost 2004).
