The Barrytown Flats are a 17 km (11 mi) coastal plain north of Greymouth on the West Coast of New Zealand's South Island. A series of postglacial shorelines and dunes backed by a former sea cliff,[1] they was originally covered with wetland and lowland forest, including numerous nīkau palms (the southern limit of this species on the West Coast).[2] The sands were extensively sluiced and dredged for gold from the 1860s, centred on the small settlement of Barrytown.[3] The drier areas of the flats have been converted into pasture, but significant areas of forest remain, including Nikau Scenic Reserve.[4] The flats are bordered by Paparoa National Park and the only breeding site of the Westland petrel (Procellaria westlandica).[5] There are significant deposits of ilmenite (titanium dioxide) in the Barrytown sands, and there have been several mining proposals, but the possible environmental consequences have been contentious.[citation needed]
