Justification of Red List category
This species is restricted to an Area of Occupancy of 72 km2. Its range is severely fragmented, with continuing decline in area and quality of habitat (MMA 2014). It is therefore listed as Endangered.
Population justification
The global population size has not been quantified, but this species is described as 'rare' (Stotz et al. 1996).
Trend justification
Despite a lack of data on population trends, slow declines are suspected to be occurring, owing to habitat loss and degradation.
Scytalopus novacapitalis occurs in swampy gallery forest and dense streamside vegetation in Goiás, Distrito Federal and west Minas Gerais, central Brazil. It is mostly rare, occurring at low densities, but can be locally common (Silveira 1998). It is known from six protected areas (Wege and Long 1995, Machado et al. 1998), and suitable habitat has been less affected by clearance for agriculture than adjacent campo cerrado habitats. Nevertheless, the annual burning of adjacent grasslands must limit the availability and extent of suitable habitat (Machado et al. 1998). Wetland drainage and the sequestration of water for irrigation schemes is further reducing habitat (Machado et al. 1998).
This species occurs in swampy gallery forest and dense streamside vegetation at 860-1100 m. It is strongly associated with permanently flooded areas dominated by Blechnum ferns and Euterpe palms (del Hoyo et al. 2003).
The population trend is suspected to be declining moderately rapidly owing to habitat loss and degradation. Due to the low agricultural potential of this species's favoured habitat, it has not been greatly affected by clearance for agriculture. Nevertheless, the annual burning of adjacent grasslands must limit the availability and extent of suitable habitat (Machado et al. 1998). Wetland drainage and the sequestration of water for irrigation schemes is further reducing habitat (Machado et al. 1998). The species’s range is severely fragmented, with continuing decline in area and quality of habitat owing to pollution, water extraction, trampling by livestock and mining.
