. Bulletin (Pennsylvania Game Commision), no. 11. Game protection; Birds. Photograph by John B. Sedam Game management students, Pennsylvania State College, examining food development work on State Game Lands. Protectors and Refuge Keepers, constantly endeavor to supplement the natural supply of food with grains placed in shelters. Sportsmen, too, throughout the State are becoming more and more interested in this vital phase of game conservation work. The natural food supply can be augmented by two principal methods: first, the planting of various kinds of shrubs, trees, vines, grains and grasses which will eventually produce nuts, berries, and seeds desirable as food for game; and second, the distribution of grains, nuts and dried plants, usually in winter when deep snows make emergency winter feeding necessary. TREES AND SHRUBS WHICH PRODUCE GAME FOOD AND COVER Assisting nature in producing suitable foods for game and birds by planting trees, shrubs, and so forth, is desirable where practicable. Many varieties of shrubs and trees produce berries, fruits and nuts which persist well into and often through the winter, and furnish excellent food. Such species of shrubs and trees may be planted on favorable locations, but it is a waste of time and money to plant unless the planted stock will receive sunlight necessary for it to become established and to grow. Most of these species will not grow satisfactorily in dense shade; in fact, they almost invariably demand an abundance of sunlight, which means they can be expected to grow only on open areas within the woods, or on abandoned agricultural lands.. riiotOKiaph l»y Dr. C.
