Prairie sandreed
Prairie sandreed (Calamovilfa longifolia) sends long, tough rhizomes through loose sand, making it the single most effective native grass for stabilizing blowouts and sandy CRP acres in the northern and central Plains.
Why landowners plant prairie sandreed
- Rhizomes spread aggressively through pure sand, halting wind erosion.
- Tall coarse stems provide winter cover and snow catch for pheasants and deer.
- Extremely drought-tolerant with a deep, fibrous root system.
- Standard sand-site component in Dakotas, Nebraska, and Montana CRP plans.
Site fit
Deep sands, sandy loams, and dune sites. Not appropriate for productive loam or clay ground, where it is both unnecessary and outcompeted. Excellent in sandhill CP2 and CP25 plantings.
Establishment
Seed is chaffy and needs a native drill. Plant 1/4 to 1/2 inch deep. Establishment is moderately slow, but rhizome spread from year two on fills gaps quickly.
Management
Forage quality drops as stems mature, so graze early if grazing is authorized. Burns well on a 4–6 year rotation. Does not require fertility inputs.
CRP practice fit
Core stabilizing grass on sandy native grass plantings.
Sandhills mix component for cover and erosion control.

Frequently asked questions
Prairie sandreed, usually paired with sand bluestem and sand lovegrass. Its rhizomes travel through loose sand and knit the surface together faster than bunchgrasses can.
It is useful early in the season but coarsens quickly. Graze early or use it primarily for cover and erosion control.
