Prairie Sandreed (Calamovilfa longifolia)

Calamovilfa longifolia, commonly known as prairie sandreed or sand reedgrass, is a native grass species of North America.

This plant has been referred to as having a stiff culm and long, tapering leaves.
This species is rhizomatous and may spread.

Scientific Name: Calamovilfa longifolia (Hook.) Scribn.
Common Names: Prairie sandreed, sand reedgrass, big sandgrass, sand reed
Family: Poaceae (Grass family)
Synonyms: The provided text mentions Calamovilfa longifolia (Hook.) Scribn. It may imply other related taxonomic ranks.

Prairie sandreed is native to North America, specifically the Great Plains and adjacent areas.
It is commonly found on sandy rangelands, particularly in central and eastern Colorado.
It thrives on well-drained sites, especially deep sands, and at elevations ranging from 2,000 to 6,000 feet.
The plant is also found in the northern Great Plains states.

Prairie sandreed is a sod-forming, perennial grass.
It typically grows to a height of 2 to 6 feet (20-60 inches).
The culms (stems) are erect, usually solitary, stout, and glabrous (smooth). They can be solid or hollow near the base.
The leaves are long and tapering, with flat blades near the base that roll inward towards the tip, creating a thread-like appearance.
The seed head is 4-16 inches long.
It exhibits a warm-season growth pattern and is a long-lived species with strong creeping rhizomes.
Pale green leaves.

Prairie sandreed is a valuable soil-binder, used for the stabilization of sandy areas prone to wind erosion.
It contributes to plant community diversity.

Prairie sandreed has some value as forage for livestock, though it is described as moderately palatable.
It can be used for grazing, rangeland, and hayland purposes.
It's used in reclamation projects for soil stabilization and diversification.

The text mentions studies on the effects of grazing (defoliation) on prairie sandreed.
Atrazine (a herbicide) can influence the presence of other plant species (sand bluestem) but may not affect prairie sandreed directly.

'Goshen' and 'Bowman' are mentioned as cultivars of prairie sandreed, developed in Nebraska.
