Tree harvesting in pinyon-juniper w/oodlands increases grass yield and quality. 

 Yield per unit area was greater on tree-associated soil microsites than in the 

 interspace between cut stems. All grass species had higher nitrogen and phos- 

 phorus levels following tree removal. Tree harvesting reduced the area required 

 per animal unit month from 27 to 7 acres (11 to 3 ha) (north aspect) and 42 to 5 

 acres (17 to 2 ha) (west aspect), but had no effect on the south aspect (40 

 acres, or 16 ha). Tree harvesting is a viable method to increase forage produc- 

 tion for livestock and wildlife.
