Portulaca samhaensis is restricted to the summit plateau of Samha where it has a total estimated area of occupancy of less than 10 km². It is predicted that there will be a decrease in the quality of the habitat on the plateau due to the recent change in livestock management on the island. Until very recently goats and sheep were actively herded and moved down from the limestone plateau during periods of drought. However, both the sheep (now largely feral) and the goats (actively managed only when in milk) are now left to roam freely for most of the year. Both animals are known to spend much of their time grazing on the limestone plateau and this could quickly lead to over-grazing and the eradication of plants on all but the most inaccessible ledges.

|Current Population Trend:||Unknown|
|Habitat and Ecology:||Open woody-herb community and dwarf shrubland on rolling limestone plateau. Altitude of 650–700 m.
Clearly closely related to P. quadrifida and P. kuriensis but differing in the smaller stature and the ground-hugging stems which trail across the ground giving a necklace-like appearance.
