IMPROVEMENT OF HABITAT ON AGRICULTURAL LANDS 



Interest is currently expressed in the possibilities of improving 

 wildlife habitat on agricultural lands. Table 4 indicates the per- 

 centage of agricultural land on which farm managers and conserva-

Table 4 indicates that 58 percent of the land in farms. 90 percent of 

 the agricultural land not in farms, and 70 percent of the nonagricul-
