Ecological relationships of smooth brome and intermediate wheatgrass with native species were investigated through comparison of seeded and nonseeded sites in aspen-mountain brush communities, on the Great Basin Research Area, Manti-La Sal National Forest. These sites were adjacent to each other, and vegetatively comparable prior to seeding. Within a 40-year period, the two sod-forming seeded grasses gained dominance and reduced native herbs and shrubs. Both introduced grasses are commonly planted to stabilize wildlands, but they are proving to be noncompatible with most native species and ultimately dominate seeded sites.
