Uses and Management:

Small burnet grows well in arid environments, and is often chosen as part of seeding mixtures on western rangelands. It establishes well from commercial seed, and can be established in 1-2 years. Areas with Small burnet should be rested every 3 or 4 years to allow for seed to set. 

Small burnet is often used for reseeding after fires for erosion control and to help deter invasive and noxious weed establishment. It is also used in seeding greenstrips for fire control.  Small burnet has been planted, along with other forbs, to control cheatgrass, red brome, and medusahead. It competes fairly well once it has established.

Small burnet provides good forage for many types of wildlife, including big game, rabbits, and birds including Greater sage-grouse. It provides high-value forage for livestock and is especially valuable as sheep forage. It generally stays green and palatable throughout the growing season and into winter. It is high in protein and carotene. 

Leaves are high in Vitamin C and used fresh off the plant in salads, soups, herbal butters, vinegars, or cold drinks. They are said to taste like cucumber.
