Letter from Frederic Leopold to A.S. Hawkins regarding hunting and the effect on duck populations, January 13, 1988. The letter voices reasons why Leopold disagrees with the theory of unsuitable habitats as a cause for the declining duck population. F. Leopold references his brother, Aldo Leopold, and his book "Game Management" as well as the philosophy of limiting factors. F. Leopold expresses his belief that spending more money on habitat improvement will not produce more ducks and the best solution would be to have less hunting of ducks.
