Game Survey of the North Central States 



A new gully eat- 

 ing the heart out of 

 a field. The vegeta- 

 tion starting in the 

 bottom of this gully 

 may heal it and also 

 make game cover if 

 left ungrazed. 



A neglected gully 

 which has cut deep 

 and become so steep 

 that stock cannot 

 graze its walls. Ac- 

 cordingly a little 

 protective vegetation 

 has started, but the 

 field will be ruined 

 by its lateral exten- 

 sions. 



A healed gully 

 with game cover 

 partially restored 

 and protected from 

 grazing.
