This remarkable succulent is endemic to the island of Abd al-Kuri where ca. 250 mature individuals are found at a single location covering less than 10 km². The latex of Euphorbia abdelkuri is toxic and the plant therefore is not eaten by livestock, so it is under no immediately perceivable threat except perhaps from collection by succulent enthusiasts. It is not found in similar habitats at other locations on the island perhaps suggesting that there has been a decline in its extent of occurrence. That it was once more abundant is confirmed by Forbes (1903) who comments This Euphorbia grows all up the side of Gebal Saleh [where it still grows] from about the upper two-thirds (500–1500 ft.), sending up its leafless stems like a forest of green candles . It was classed as Endangered in the Red Data Book (1977). The population of E. abdelkuri on Abd al Kuri lie within an area designated as a Nature Sanctuary within the zoning plan for the Soqotra Archipelago.
