• Reduce lawn area and the amount of young shoots within lawns.
• Replace mowed, fertilized grass with other plantings or materials.
• Allow grass to "naturalize." Grass at least 6 inches high has fewer young, tender shoots, and the shoots are more difficult for geese to find.
• End or reduce fertilizer use and supplemental watering to reduce young shoots.
• Reduce sight lines and access to open water. Geese like open sight lines and begin to feel insecure when they cannot see everything within at least 30 feet.
• Add plantings such as long grasses, shrubs or other dense tall plants along shorelines.
• Use fences, hedges and a continuous band of emergent aquatic plants like cattails and bulrushes in the water at the shoreline, alone or in combination with other elements.
• Mix boulders — 2 feet or larger in diameter and more than 12 inches high — with plants.
