By comparison, migratory Canada geese across the continent only increased from 1.8 to three million birds during that same period. It is easy to see why the resident birds have flourished. From a goose's point of view, lakeshore lawns, parks, and golf courses offer short, succulent grass, open water and few predators - in other words, ideal habitat for feeding and loafing. But there are problems. If geese are not welcome on your property, you can work to discourage their visits.
Prevention is the key.
Make your property less attractive to geese. Don't feed geese. Plant dense hedges or erect fencing near lakeshore areas to reduce access. Check your property frequently for nest building activity during the spring, and remove any nesting materials found. Harass geese that frequent your property.
