This publication is meant to reflect birdsfoot trefoil establishment and maintenance costs on a small-scale cattle grazing area (5 to 10 acres). Birdsfoot trefoil is a perennial legume, and under proper irrigation and management, stands in northern Utah can persist for up to 8 years after seeding. Establishment costs are amortized annually based on a 6 year stand life.
