The Hawaiian tropical low shrublands are a tropical savanna ecoregion in the Hawaiian Islands. These shrublands cover an area of 1,500 km2 (580 sq mi) in the leeward lowlands of the main islands and most of the smaller islands, including the Northwestern Hawaiian Islands. The ecoregion includes both grasslands and mixed shrublands. Kāwelu (Eragrostis variabilis), mauʻu ʻakiʻaki (Fimbristylis cymosa), ʻakiʻaki (Sporobolus virginicus), and Lepturus repens are common grassland plants. Shrublands are dominated by ʻilima (Sida fallax), ʻaʻaliʻi (Dodonaea viscosa), naupaka (Scaevola spp.), hinahina kū kahakai (Heliotropium anomalum var. argenteum), kīpūkai (Heliotropium curassavicum), maʻo (Gossypium tomentosum), ʻakoko (Euphorbia spp.), ʻāheahea (Chenopodium oahuense), naio (Myoporum sandwicense), kolokolo kahakai (Vitex rotundifolia), and pūkiawe (Styphelia tameiameiae).[2] More than 90% of the plant species found in this ecoregion are endemic, including ʻōhai (Sesbania tomentosa),[4] ʻāwiwi (Schenkia sebaeoides), and wahine noho kula (Isodendrion pyrifolium).[5]
