Conservation

The IUCN Red List conservation status of the Leaden Antwren is assessed as Least Concern. This species has a wide distribution, and the population trend, although not quantified, is believed to be stable (BirdLife International 2011).

The relative abundance of the Leaden Antwren is assessed as "fairly common" across the range of the species (Ridgely and Tudor 2009), and as "uncommon" in Peru (Schulenberg et al. 2007).

Effects of human activity on populations

Human activity has little short-term direct effect on the Leaden Antwren, other than the local effects of habitat destruction. Given that this species occupies disturbed habitats, it may even benefit, locally, from human activities, such as a low level of clearing for subsistence agriculture. In the longer term, the Leaden Antwren 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.
