COVER: 'I'lus exclosure on the Beaver District of the Fishlake 

 National Forest is typical of the many two-part exclosures 

 found chi'oughout Utah. In this exclosure, cattle were ex- 

 cluded, while deer were permitted behind the fence in the 

 area on the right. Both cattle and deer were excluded in 

 the area on the left. Note lack of aspen reproduction 

 where deer were permitted and abundant reproduction 

 where they were excluded.
