game and song birds and devour the eggs or young found therein. 

 These depredations must be controlled if fish and game resources are 

 to be fully developed. 



MANAGEMENT OF THE GAME AND FISH RESOURCES 



Certain definite requirements must be met in. order to provide for 

 the greatest production and use of these resources. Very briefly these 

 requirements are as follows : 



SUITABLE ENVIRONMENT 



Without suitable cover, shelter, and food, game and fish can not 

 thrive. The settling up of the open areas made the preservation of 

 the buffalo as a game animal impossible and has greatly restricted 

 the antelope. The utilization of forage by livestock on essential 

 winter range may destroy game. When the winter feeding grounds

are occupied by settlers, some substitute may be provided, such as 

 protecting winter feed areas from use by domestic stock and supple- 

 menting natural feed as necessary. The planting of shrubs producing 

 fruits available in winter may benefit game birds. The pollution of 

 streams or the diversion of a large proportion of the water destroys 

 the fish. Conditions causing erratic stream flow and more frequent 

 floods make difficult the existence of fish life. 



CONTROL OF NATURAL ENEMIES 



Predatory animals or birds may utilize all the game produced and 

 make protective laws unavailing. It is sometimes claimed that where 

 predatory animals are at all numerous they kill more game than do 

 hunters. 



PROVISION FOR INCREASE 



An adequate brood stock, or in the case of fish, a stock to supply 

 spawn must be maintained. Protection during the breeding, rearing,
