Habitat and Ecology
This is a montane forest inhabitant that is now found in Puna grassland as a result of deforestation. It can be found in gardens, potato fields, and other similar habitats. It is presumed to breed by direct development.
It is an uncommon species.
The major threat to this species in the past was loss of forest habitat, but the species seems to have adapted relatively well in the face of such habitat degradation. There are no immediate threats at present, although agrochemical pollution might pose a threat in the future.
It does not exist in any protected areas. There is a need for close population monitoring of this species given its very restricted range.
