Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Sea Purslane faces severe threats from coastal development, sea level rise, and habitat degradation of its specialized salt marsh environments. The species is particularly vulnerable to climate change impacts that alter salinity levels and flood patterns in its narrow coastal habitat range, while urban expansion and infrastructure development continue to fragment and destroy remaining populations.
Key Facts
Habitat & Distribution
Salt marshes, mudflats, and brackish coastal wetlands in the upper and middle intertidal zones. Typically found in areas with moderate to high salinity levels along estuaries, coastal lagoons, and sheltered shorelines.
