Chestnut Antpitta Grallaria blakei

Justification
This species has a small range, and numbers are likely to be declining as a result of continuing habitat loss. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Distribution and population
Grallaria blakei is very patchily distributed in the Andes of north and central Peru where it is generally uncommon (Ridgely and Tudor 1994). Disjunct populations occur in San Martín, Amazonas, Huánuco and Pasco (Ridgely and Tudor 1994, Hornbuckle 1999b).

Population justification
The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).

Trend justification
A moderate and on-going population decline is suspected to be occurring, as habitats within this species's range continue to be destroyed and degraded at a rapid rate.

Ecology
It inhabits montane forest and secondary woodland, generally on or near the ground, preferring areas with a dense bamboo understorey (Ridgely and Tudor 1994). Although largely recorded in a very narrow altitudinal band, 2,150-2,475 m (Ridgely and Tudor 1994), it occurs at 1,850 m in the Cordillera de Colán (Davies et al. 1997) and was recently recorded at 2,400-2,900 m at Abra Patricia, San Martín (D. Lane in litt. 2002).

Threats
It is primarily threatened by habitat destruction. In the Cordillera de Colán, deforestation is proceeding at an alarming rate, with most forest in this area already cleared, and what remains rapidly being converted to cash crops, particularly marijuana and coffee (Davies et al. 1997).

Conservation Actions Underway
Conservation Actions Proposed
Conduct surveys of suitable habitats within and surrounding the known range to determine its true distribution and abundance. Ensure that remaining tracts of suitable habitat receive adequate protection.
