Trisyngyne perryi

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, which if not managed sustainably, could be a direct threat. 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). Given the abundance of the species in Papua New Guinea, the large size of the tree and the fact it is an excellent hardwood, all suggests that this species is forested regularly. In a herbarium specimen, the collector notes that one individual had a diameter of 4 m and 18 m in height, suggesting it was a remnant tree from the original forest (Paijmans 1971).

According to BGCI Plant Search (2017), this species is not found in any ex situ collections; effort must be made to preserve it. Its presence within protected areas requires confirmation.
