AbstractThe effects of aspen overstory basal area on herbaceous understory production on the Bears Ears District of the Routt National Forest in northwest Colorado were investigated. Using regression, a coefficient of determination of .61 was found between herbage production and overstory basal area. For overstory basal areas less than 10.0 meter2}/hectare, herbaceous understory production varied considerably and was often double that found at higher densities of overstory basal area. Herbage production at higher densities (10.0 to 18.9 $m2/ha) showed less variation with an average production of 1100 kilograms/hectare. The best opportunities for herbaceous understory production in unmanaged, pure aspen stands occur at overstory basal areas less than 10.0 m2/ha.
