| Population: | This species has not be trapped since Hutterer (1994) despite several attempts (Saavedra et al., 2003). It is thought that the population is now extremely small. |
| Population Trend: |
Decreasing
|
| Habitat and Ecology: | The island supports dense vegetation that is biogeographically related to mainland Valadivian forest. It occupies only a few square kilometers of forest habitat. |
| Systems: | Terrestrial |
| Major Threat(s): | The islanders rely heavily on the vegetation for their subsistence which has led to significant degradation of the natural habitats. Human activity has resulted in the almost total deforestation of lowlands which are now dominated by grasslands. The Valdivian forest is now restricted to the highest elevations and subject to logging. |
| Conservation Actions: | Further trapping efforts should directed to mountain tops. |
