Hawaiian Tropical High Shrublands
The Hawaiian tropical high shrublands are a tropical savanna ecoregion in the Hawaiian Islands. Geography The high shrublands ecoregion covers an area of on the upper slopes of the volcanoes Mauna Kea, Mauna Loa, Hualālai, and Haleakalā. Flora The plant communities include open shrublands, grasslands, and deserts. Shrubland species include āheahea (''Chenopodium oahuense''), ōhelo ai ('' Vaccinium reticulatum''), naenae ('' Dubautia menziesii''), and 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 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 uau (''Pterodroma sandwichensi ...

Haleakalā
Haleakalā (; Hawaiian: ), or the East Maui Volcano, is a massive shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui Mountains. The tallest peak of Haleakalā ("house of the sun"), at , is Puu Ulaula (Red Hill). From the summit one looks down into a massive depression some 11.25 km (7 mi) across, 3.2 km (2 mi) wide, and nearly 800 m (2,600 ft) deep. The surrounding walls are steep and the interior mostly barren-looking with a scattering of volcanic cones. History Early Hawaiians applied the name ''Haleakalā'' ("house of the sun") to the general mountain. Haleakalā is also the name of a peak on the southwestern edge of Kaupō Gap. In Hawaiian folklore, the depression (crater) at the summit of Haleakalā was home to the grandmother of the demigod Māui. According to the legend, Māui's grandmother helped him captu ...

Chenopodium
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascen ...

Panicum Tenuifolium
''Panicum'' (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known ''Panicum'' species include ''Panicum miliaceum'' (proso millet) and ''Panicum virgatum'' (switchgrass).

Eragrostis Atropioides
''Eragrostis'' is a large and widespread genus of plants in the grass family, found in many countries on all inhabited continents and many islands. ''Eragrostis'' is commonly known as lovegrass or canegrass. The name of the genus is derived from the Greek words ἔρως (''eros''), meaning "love", and ἄγρωστις (''agrostis''), meaning "grass". Lovegrass is commonly used as livestock fodder. The seeds appear to be of high nutritional value for some animals, but they are also very tiny and collecting them for human food is cumbersome and hence uncommon. A notable exception is teff ('' E. tef''), which is used to make traditional breads on the Horn of Africa, such as Ethiopian ''injera'' and Somalian ''laxoox''. It is a crop of commercial importance. '' E. clelandii'' and '' E. tremula'' are recorded as famine foods in Australia and Chad, respectively. Other species, such as '' E. amabilis'', are used as ornamental plants.

Tussock Grass
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat w ...

Dubautia Menziesii
''Dubautia'' is a genus of flowering plant in the family Asteraceae. The genus was named after Joseph Eugène DuBaut (1796-1832), an officer in the French Navy who participated in Freycinet's expedition. The entire genus is endemic to Hawaii. It contains more species than the other two genera in the silversword alliance, including cushion plants, shrubs, trees, and liana A liana is a long- stemmed, woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight.
