We have six volunteers who are managing the Fish & Wildlife Service permit that allows us to control the Canada Goose population on Truesdale Lake.
The permits allow us to addle and oil the eggs to prevent the eggs from developing and greatly reduces the number of Canada Geese on Lake truesdale not only the current year but also in subsequent years as it changes the migratory behavior of the targeted geese.
The mated geese end up spending their valuable incubation time on the nest with intact but non-developing eggs. Then after a failed nesting the geese pair continues their migration to the Canadian Tundra which is their natural summer feeding grounds. (See PDF information for more detail)
