Montipora grisea has a vast range, found within the reefs of forty-five countries and territories throughout the Indian and Pacific oceans.[1] It exists at depths of 3 to 20 meters, with a preference for "shallow, tropical reef environments on upper reef slopes." [1]

Despite being considered a common species with a presently large population, Montipora grisea faces an array of threats.[1] It is moderately susceptible to bleaching, though notably less so than Acropora corals.[1] Other threats include predation from the crown-of-thorns starfish, harvesting for the aquarium trade, climate change and ocean acidification.[1]
