A previously unreported population of Salicornia europaea has been found on the edges of a small tidal inlet in the emirate of Umm al-Qaiwain. It appears to be different from two ecotypes of the species found in other parts of the United Arab Emirates (UAE). The location has large numbers of an introduced halophytic plant species, Sesuvium portulacastrum, which serve to inhibit the growing of local species. The number of plants of the local S. europaea ecotype is low and the species may disappear. The eradication of the alien species of S. portulacastrum from the area is necessary to protect the S. europaea ecotype and other local flora in the area.
