Koeleria macrantha is a species of grass known by the common name prairie Junegrass in North America and crested hair-grass in the UK. It is widespread across much of Eurasia and North America. It occurs in many habitat types.

Contents

Description

Koeleria macrantha is a short, tuft-forming perennial bunchgrass, reaching heights from 20–70 centimetres (8–27+12 inches). The leaves are basal and up to about 20 cm (8 in) long [1] with a blue-green color. [2] The inflorescence is nearly cylindrical and may taper somewhat toward the tip. It holds shiny tan spikelets which are sometimes tinted with purple, each about half a centimetre long. [3] Its fruit is a grain that breaks once it has fully ripened. [2]

Distribution and habitat

Koeleria macrantha is widespread across much of Eurasia and North America. [4] [5]

It is a plant that prefers cooler seasons such as early spring or fall. It grows mostly in rocky or sandy, well-drained areas within forests or plains. It prefers more direct sunlight over partially shaded areas. [6] It has the ability to grow at elevations of 121–2,480 metres (397–8,136 feet) above sea level. [7] It often surfaces in prairie habitats.

Ecology

Koeleria macrantha is a good forage for many types of grazing animals. It is one of many dietary staples for all classes of livestock and several species of various prairie wildlife depending on the stage of its seasonal development. It provides a stable source of nourishment for livestock in early spring and has been utilized by several species of deer, elk, and sheep as a food source due to its ability to grow in remote areas where the environment is not suited for other plant life. Due to the fact that it grows in scattered areas, it has not become a large dietary staple for much wildlife but still provides moderate nourishment to prairie wildlife. It has been found to be palatable to all livestock and wildlife in its post-curing stage in spring and fall but the palatability drops for most species when seed production begins before curing. [3]

Koeleria marcrantha spreads slowly via seed distribution. It will spread into bordering plant communities over time as an invasive species. [8] A number of insects feed on K. macrantha, including the striped flea beetle (Phyllotreta striolata) which feeds on the roots and foliage. [8]

Toxicity

It is classified as a severe allergen in humans with grass allergy. [9]

Uses

The seed can be ground into a powder, which can then be boiled in water like a porridge or made into flour or bread. [10]

The leaves of the plant can be woven together to make brooms or brushes. Long stalks of the plant can be strung together with other plant fiber or string to be used for cleaning pots and pans. It has also been used as a building material when mixed with adobe for its adhesive qualities and strength. [10]

Gardens

Koeleria macrantha is used as an exceptionally low-maintenance lawn and turf grass. It is not suitable for high-traffic use due to its slow growth rate. It is often used for golf course roughs. [1]

Wildfire protection

Koeleria macrantha has been implemented in several areas of frequent wildfires due to its fire-resistant qualities. Due to its small size and the coarse leaves, they burn faster and transfer a very small amount of heat to the soil below. It also usually grows in small groups, which limits the amount of damage it can do once it burns. Although this species varies in its impact on fighting wildfires depending on the environment it grows in and the state of the plant, it provides a much needed damper for controlling the fire once it has begun. [3]

<span class="mw-page-title-main">Grassland</span> Area with vegetation dominated by grasses

A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.

<span class="mw-page-title-main">Rangeland</span> Biomes which can be grazed by animals or livestock (grasslands, woodlands, prairies, etc)

Rangelands are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers.

<span class="mw-page-title-main">Fire ecology</span> Study of fire in ecosystems

Fire ecology is a scientific discipline concerned with the effects of fire on natural ecosystems. Many ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as an essential contributor to habitat vitality and renewal. Many plant species in fire-affected environments use fire to germinate, establish, or to reproduce. Wildfire suppression not only endangers these species, but also the animals that depend upon them.
