The flora of Atiu can be divided into five ecological zones. The "pa tai" (coast) and "Rautuitui" (upland "makatea"), are dominated by coconuts and "Pandanus tectorius", with patches of "Barringtonia asiatica", "Elaeocarpus tonganus", and "Hernandia moerenhoutiana". The "Puna" (swampy lowlands) are cultivated for taro, with grasses and forests in the drier parts. The "Rautuanue" (slopes) and "maunga" (mountain) are dominated by "Platycerium", "Casuarina", and crops of pineapple and yams.
