Sand Dropseed Plant Description
Scientific Name: Sporobolus cryptandrus

Sand dropseed is a long-lived perennial warm season bunchgrass, native throughout North America. This species produces a dense, sand binding network of roots which can spread up to 2 feet laterally and over 8 feet deep. Sand dropseed is a prolific seed producer. In one study, a single panicle yielded approximately 10,000 seeds (Brown, 1943). Seeds are very small; there are approximately 5.6 million seeds/lb.

Sand dropseed is widely used in disturbed area plantings in the Southwest, Intermountain West and short-grass prairies of the Great Plains. The fibrous root system effectively stabilizes sand dunes and hills. Its abundant seed production makes it a pioneer plant in disturbed areas and an invader of sandy soils.

Sand dropseed is native throughout North America but is most important as a rangeland species in the Southwest and certain parts of the Snake, Salmon, and Clearwater River drainages in Idaho and Oregon.

In the Intermountain West it sand dropseed is commonly associated with Indian ricegrass, bluebunch wheatgrass and Galletta grass in sagebrush, desert shrub and pinyon- juniper plant communities. In its southern range it is often found growing with side-oats grama and muhly species. In other regions it is common in the short-grass prairies and chaparral communities.

Sand Dropseed Adaptation

Sand dropseed is extremely drought tolerant and is adapted to sites receiving 7 to 16 inches annual precipitation (Ogle et al., 2009; USDA 2009). Its fine root system allows sand dropseed to extract water at depths. During periods of summer drought the leaves roll up to reduce surface area and evapotranspiration. It is considered to be one of the most drought resistant species in short-grass prairie.

Sand dropseed is most common at lower elevations in sandy soils but can also be found on coarse soils at upper elevations to 8,000 ft (Jensen et al., 2001; Ogle et al., 2009). It is adapted to slightly acidic to slightly basic soils and has a salt tolerance of less than 4 mmhos/cm (Dickerson, 1998).

Establishment

This species spreads naturally from seed once established and increases on depleted rangelands and wastelands. Sand dropseed plants are able to withstand heavy use due to their protected root crown, late maturity and because they are less preferred than other species.

The scientific name, Sporobolus, comes from the Greek sporos (seed) and bolos (a throw), and the common name, dropseed, both refer to the seeds which fall or may be ejected from the inflorescence when the mucilaginous fruit wall dries (Peterson, et al., 2003).
