État de la populationTexte officiel évaluation IUCNExpert
The population of this species is currently understood to be small as it is only known from type locality. It is known to grow alongside Nothofagus carrii and N. flaviramea which are both widespread species (Veblen et al. 1996).

Description complète des menacesTexte détaillé évaluation IUCNExpert
Considering its one location, and it grows alongside more widespread timber species, this could suggest the reason for its fractured locality. Shearman et al. (2009) states that since 1972, 13% of upper montane forests have been lost. Beehler and Marshall (2012) add 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 on upland slopes where 4.4% of forest loss 1972-2002 has occurred (Shearman et al. 2009). Fire, logging and conversion of land use are the most likely threats that have caused this species to diminish to one single locality.
