Trisyngyne pseudoresinosa

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. It is said that some species of Nothofagus can re-sprout 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 areas where 4.4% of forest loss 1972-2002 has occurred (Ash et al. 2009). It is clear that this species distribution has reduced dramatically over a period of 20 years. One of the herbarium specimens collected in New Britain in the 1970’s, stated that it was found at 1,500 m, which suggests that those additional subpopulations may have been cleared due to their lower elevational ranges. This additionally supports Ash et al. (2009) statement regarding loss of upper montane forests since 1972.
