Trisyngyne aequilateralis

The major threats to the species are mining and fire. It is also impacted by climate change.

The region is experiencing rapid economic growth, rising population and constant mining for nickel which is causing many species to become fragmented and extinct in parts of the island. Many of the species habituate to lower montane forests (600–800 m) which suggests that these species are unlikely to be able to shift in response to a changing climate due to poor wind dispersal and the need for specialised soil conditions.

With temperatures beginning to rise and more sporadic rain has shown fires to become more common in parts of New Caledonia. Fires have burnt in to the boundaries of Nothofagus forests in many localities and are directly responsible for the sharp boundaries often formed between rainforest and woodland or maquis. Therefore, once forest cover is lost at low altitudes following intense and or frequent fires, regeneration is less likely. Few recent Nothofagus invasions into adjacent woodland or maquis has been found that could indicate successful recovery of this species (Veblen et al. 1996). There is some regeneration in some sites where canopy cover is lost and other growth conditions ideal. It is unknown how these pressures are affecting the species to date.

According to the BGCI Plant Search (2017), there are currently no ex situ collections of this species; collections of this species should be made. This species is found in five protected areas: Rivière Bleue, Pic du Pin, Montagne des Sources, Yaté Barrage and Thy.
