 Arizona. Res. Pap. INT-391. Ogden, UT: U.S. Department of Agriculture, Forest 

 Service, Intermountain Research Station. 11 p. 



Volume prediction equations have been developed for Arizona's juniper, pinyon, oak, 

 and mesquite woodland tree species. The equations require measurements of total tree 

 height and tree diameter near the root collar. Results are presented in equation and 

 tabular formats. Volume equation construction, volume equation reliability, and compari- 

 son of the results with other studies are discussed.
