Trisyngyne grandis

Where logging occurs and disturbance is not too destructive, occasionally Nothofagus spp. can be found in secondary or logged forests. However, where impacts are too destructive, grasslands and secondary forest may develop. 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 little literature supports this other than one location found within a logging area (Clunie 1975). According to Ash et al. (2009), between 1972 and 2002, a net 15% of Papua New Guinea’s tropical forests were cleared and 8.8% were degraded through logging. In addition, since 1972, 13% of upper montane forests have also been lost. Furthermore, 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 (Ash et al. 2009). Given the abundance of the species across Papua New Guinea and the size of the tree, it is likely it is used as a timber species which could threatened the species if not managed sustainably. Considering its altitudinal range, it also likely to suffer from fire damage.

The species is found in one ex situ collection worldwide (BGCI Plant Search 2017). The species presence within protected areas should be investigated and confirmed.
