Chapter 6 Chapter 6 – Game and Other High-Interest Species The childhood training of hunters is not so much practical training as the opening of spiritual doors.... Hunting had put a premium on physical good health, on sensitivity to environment and to the nuances and clues in a delicate and beautiful world, on independence, confidence, persistence, generosity, and had given them a powerful sense of the non-human creation. — Paul Shepard (1973) There is a value in any experience that exercises those ethical restraints collectively called ‘sportsmanship.’ Our tools for the pursuit of wildlife improve faster than we do, and sportsmanship is a voluntary limitation in the use of those armaments... a peculiar virtue of wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct. Whatever his acts, they are dictated by his own conscience rather than by a mob of onlookers. It is difficult to exaggerate the importance of this fact. — Aldo Leopold (1966) Key Questions nia head for the lakes, where a variety of popu- • What is the current status of major lar sport fish are planted.
