Artenschutz: Metriaclima flavicauda wurde nicht durch die Internationalen Union für die Erhaltung der Natur (IUCN) in der Roten Liste bedrohter Arten bewertet. Although M. flavicauda is rather common at Zimbawe Rock and at the rocky pinnacle near Mumbo Island, these two localities are the only areas of known distribution of this species. The fact that these two places are rather small the species should be listed as vulnerable to extinction.
