Sonneratia hainanensis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Sonneratia hainanensis faces severe population decline due to extensive coastal development and mangrove habitat destruction along China's southern coastlines. The species is particularly vulnerable to aquaculture expansion and port construction, which directly eliminate the intertidal mudflats and mangrove edges where it naturally occurs. Rising sea levels and increased storm intensity from climate change further threaten the remaining fragmented populations by altering the delicate salinity and tidal regimes essential for its survival.

Threat summary

Habitat

Sonneratia hainanensis inhabits the intertidal zones of mangrove forests and estuarine mudflats along tropical coastlines, particularly thriving in areas with regular tidal flooding and brackish water conditions. The species requires specific salinity gradients and soft sediment substrates found at the interface between terrestrial and marine environments.
