État de la populationTexte officiel évaluation IUCNExpert
According to Beehler and Marshall (2012), it is stated that the species was plentiful at 2,300 m alongside N. brassii and N. starkenborghii. There is continuing decline in mature individuals due to logging and deforestation.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Since 1972, 13% of upper montane forests have been lost (Ash et al. 2009). The present trend for Nothofagus forest is to be reduced in area, through conversion to other land uses (Beehler and Marshall 2012). Being a large tree, it is likely that this could be used as a timber species, yet there is no literature to support this statement. It is said that some species of Nothofagus can resprout in secondary forest, but where impacts are too destructive it is unable to. In addition, seasonal fires are becoming more prevalent and beginning to occur in logged areas, especially in upland slopes where 4.4% of forest loss between 1972-2002 has occurred (Ash et al. 2009). Considering this species is a large tree and found at low elevation, there is a strong possibility it is under threat from logging as well as fires.
