North Dakota State University (NDSU) Extension’s recent study on grazing intensity across 51 locations in 12 counties revealed that pastures with light to moderate grazing experienced the highest growth, while severe grazing drastically reduced forage production by up to 57% in 2022 and 54% in 2023. Researchers Miranda Meehan and Kevin Sedivec underscored the need for effective grazing management, stressing that maintaining a grazing plan and monitoring usage are crucial to mitigating long-term damage to grassland resources.
To promote healthy regrowth, producers should avoid grazing grasses below a height of three to four inches, particularly in the fall when cool-season grasses are storing carbohydrates and regenerating roots. Experts from South Dakota State University and Penn State Extension also emphasize that proper stubble height prevents overgrazing, which can impair future growth. NDSU advocates for proper stocking rates and using tools like grazing sticks to manage pasture use effectively. Additionally, University of Minnesota Extension’s Craig Shaeffer notes the importance of controlling weed growth, which can increase when drought weakens cool-season grasses.
