Elymus wawawaiensis is a species of grass known by the common name Snake River wheatgrass. It is native to western North America, where it occurs in the Pacific Northwest. It is native to eastern Washington and Oregon and parts of Idaho. [1]

Contents

The Elymus wawawaiensis grass is long-lived and drought-tolerant. There are cultivars available, including 'Secar', which is especially tolerant of drought. [2] Other cultivars include 'Discovery'. [3]

Uses

Elymus wawawaiensis is good for binding soil to prevent erosion. It can be added to a mix of native seed and sown on dikes and ditches. It is tolerant of cold conditions and of fire. [1] It is also popular for use in rangeland and habitat restoration throughout the American West. [1]

This grass is a good graze forage for livestock and wild ungulates. It can have up to 20% protein in the spring. [1]

Snake River Plain (ecoregion)

The Snake River Plain ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Idaho and Oregon. It follows the Snake River across Idaho, stretching roughly 400 miles (640 km) from the Wyoming border to Eastern Oregon in the xeric intermontane west. Characterized by plains and low hills, it is considerably lower and less rugged than surrounding ecoregions. Many of the alluvial valleys bordering the Snake River are used for agriculture. Where irrigation water and soil depth are sufficient, sugar beets, potatoes, alfalfa, small grains, and vegetables are grown. Elsewhere, livestock grazing is widespread. Cattle feedlots and dairy operations are found locally.

<i>Thinopyrum intermedium</i>

Thinopyrum intermedium, known commonly as intermediate wheatgrass, is a sod-forming perennial grass in the Triticeae tribe of Pooideae native to Europe and Western Asia. It is part of a group of plants commonly called wheatgrasses because of the similarity of their seed heads or ears to common wheat. However, wheatgrasses generally are perennial, while wheat is an annual. It has gained the Royal Horticultural Society's Award of Garden Merit.

<i>Elymus trachycaulus</i> Species of flowering plant

Elymus trachycaulus is a species of wild rye known by the common name slender wheatgrass. It is native to much of North America. It grows in widely varied habitats from northern Canada to Mexico, but is absent from most of the southeastern United States.

<i>Leymus cinereus</i>

Leymus cinereus is a species of wild rye known by the common names basin wild rye, Great Basin wild rye, and Great Basin lyme grass.

<i>Elymus lanceolatus</i> Species of grass

Elymus lanceolatus is a species of grass known by the common names thickspike wheatgrass and streamside wheatgrass. It is native to North America, where it is widespread and abundant in much of Canada and the western and central United States. There are two subspecies, ssp. lanceolatus occurring throughout the species' range and ssp. psammophilus occurring in the Great Lakes region. Elymus lanceolatus is a perennial, low growing, rhizomatous grass that actively grows in summer and spring. This plant is native to semiarid regions of the United States.Elymus lanceolatus is polymorphic, capable of growing in high altitude regions of the Rocky Mountains or at sea level near the Great Lakes in the United States. The bloom period for E. lanceolatus is mid-spring, and it is available commercially. Elymus lanceolatus is characterized by its yellow flowers, green or grey leaves, and brown seeds. According to the United States Department of Agriculture (USDA), it has a moderate harvest regrowth rate. Wheatgrass is unique in that in can adapt to fine, medium, and coarsely textured soils in the environment. However, it is shade intolerant, has a medium fertility requirement, and has a medium salinity tolerance. Studies suggest that amounts of soil needed for wheatgrass harvest can be approximated by understanding the plant’s water depletion rate and rainfall amount in the region, which consequently helps reduce drainage.

Eragrostis curvula is a species of grass known by the common name weeping lovegrass. Other common names include Boer lovegrass, curved lovegrass, Catalina lovegrass, and African lovegrass.

<i>Psathyrostachys juncea</i> Species of grass

Psathyrostachys juncea is a species of grass known by the common name Russian wildrye. It was formerly classified as Elymus junceus. It is native to Russia and China, and has been introduced to other parts of the world, such as Canada and the United States. Psathyrostachys juncea is a great source of food for grazing animals, as it has high nutrition value in its dense basal leaves, even in the late summer and autumn seasons. This species can grow and prosper in many harsh environments, making it an ideal candidate for improvement as it can grow in areas were farming is difficult. This species is a drought-resistant forage plant and can survive during the cool seasons. It is also a cross-pollinator and is self-sterile. This means that P. juncea cannot self-fertilize; it must find another plant of the same species with which to exchange gametes. Self-sterilization increases the genetic diversity of a species.

<i>Dichanthelium clandestinum</i> Species of grass

Dichanthelium clandestinum is a species of grass known by the common name deertongue. It is native to eastern North America, including eastern Canada and the eastern United States.

<i>Elymus hoffmannii</i> Species of grass

Elymus hoffmannii is a species of grass known by the common name RS wheatgrass. It was described as a new species in 1996. It became known to science when some grasses were collected in Turkey in 1979 and one type was successfully bred out, proving to be a natural hybrid. E. hoffmannii is derived from this hybrid between Elymus repens and the bluebunch wheatgrasses of Turkey, such as Pseudoroegneria spicata.
