This bulletin describes birdsfoot trefoil in the Mountain West, and why it should be considered for planting. It includes cultivar selection and seeding rate, establishment considerations, and interseeding methods. Its high nutritive value and ruminant-friendly tannins will support livestock production without risk of bloat, while it fixes nitrogen to increase production in the entire pasture.
