Description complète des menacesTexte détaillé évaluation IUCNExpert
Overall the species has very little literature so no specific threats can be identified. Considering it has one locality and it is found at low altitude alongside a widespread species that is currently logged, it is more than likely logging has been the cause of reduction for this species. Ash et al. (2009) states that since 1972, 13% of upper montane forests have been lost; Beehler and Marshall (2012) adds that the trend for Nothofagus forest is to be reduced in area through conversion to other land uses. It is also possible that this species has been affected by seasonal fires which are becoming more prevalent and beginning to occur in logged areas, especially in upland slopes where 4.4% of forest loss 1972-2002 has occurred (Ash et al. 2009). Fire and logging are the most likely prominent threats causing the loss of habitat for this species. Its restricted occurrence and narrow genetic base places the species in a precarious state.
