Systems: Terrestrial

Threats [top]

Major Threat(s): The habitat shows a high rate of deforestation by forestry and agricultural activities. This species is listed as Vulnerable in the Red List but is considered a pest in some commercial forests (Rodriguez, 1993). The reliance of this species on disappearing dense woodlands is implied by its extinctions from several localities in central Chile since pre-Colombian times (Simonetti and Saavedra, 1998).

Conservation Actions [top]

Conservation Actions: It occurs within Noel Kampf and very few protected areas throughout its range. It is listed as Vulnerable for Argentina (Barquez et al. 2006) even though it is considered a pest in some commercial forests (Rodriguez, 1993).
