A clipping study was designed to simulate herded goat grazing and measure the effects on a leafy spurge (Euphorbia esula) infested rangeland on the Sheyenne National Grasslands in North Dakota. Seven defoliation treatments (no grazing, vegetative stage, flowering stage, mature stage, regrowth stage, once at vegetative and regrowth stages) were applied to all leafy spurge plants within 3 x 6 m plots annual for four years. Each clipping removed the top 5 cm of leafy spurge plants. Cover, density and herbaceous yield were estimated on four, 0.1 m² Daubinmire plots within each treatment. Total herbaceous production was clipped, dried and separated into categories for analysis.
