The Motane One Reserve is a nature reserve containing the whole of the islands of Moho Tani and Terihi, as well as the surrounding rocks, in the southern Marquesas Islands. It was declared in 1992, as the first step toward protecting the ecosystem, much of which, on Moho Tani, has been destroyed by over-grazing by feral sheep, pigs and goats. Terihi and the smaller rocks are home to large seabird rookeries.
