During March 2001-December 2003, we measured use of forage and height of stubble in pastures at low, middle, and high elevations. In years with higher precipitation, use of forage by cattle (Bos taurus) and elk (Cervus elaphus) was less in the middle elevation compared to low and high elevations. In the worst drought year on record (2002), use of forage increased with elevation. Overall, use of forage was greater in 2002 than in 2001 and 2003. Shorter stubble corresponded to lower production and higher use of forage. Total use of forage did not exceed 50%.
