Geography
Flora
The plant communities include open shrublands, grasslands, and deserts. Shrubland species include {{okina}}āheahea (Chenopodium oahuense), {{okina}}ōhelo {{okina}}ai (Vaccinium reticulatum), na{{okina}}ena{{okina}}e (Dubautia menziesii), and {{okina}}iliahi (Santalum haleakalae). Alpine grasslands are dominated by tussock grasses, such as Deschampsia nubigena, Eragrostis atropioides, Panicum tenuifolium, and pili uka (Trisetum glomeratum). Deserts occur on the coldest and driest peaks, where only extremely hardy plants such as {{okina}}āhinahina (Argyroxiphium sandwicense) and Dubautia species are able to grow.
Fauna
The nēnē (Branta sandvicensis) is one of the few birds found in alpine shrublands, while {{okina}}ua{{okina}}u (Pterodroma sandwichensis) nest in this ecoregion.
