Threats In Australia; the known population of Haines’s Orange Mangrove is threatened by habitat loss and climate change (see Table 1).
Climate change Rising sea Potential With a rising sea level; the habitat of the species will be levels current disrupted; and the species will suffer mortality at present locations.
Threats to the species include habitat loss from urban and associated infrastructure development and sea level rise associated with climate change.
Flood mitigation works could alter the hydrology and cause tree numbers to be reduced (DoEE 2016).
