| Abstract | Changes In Soil Physical and Hydrological Properties Due to Bromus Tectorum (cheatgrass) Invasion by Joshua J. Boxell Dr. Patrick Drohan, Examination Committee Chair Pine Lake Institute for Environmental and Sustainability Studies Hartwick College, Oneonta, New York Introduction of Bromus tectorum (cheatgrass) into western rangelands has had a profound effect on the diversity and health of native ecosystems. Introduced in the late 19th century, B. tectorum has rapidly out-competed native species and colonized large areas of the Great Basin region (Mack, 1981). The objective of this research is to assess changes in soil physical and hydrologie properties on former tridentata sites now invaded by B. tectorum and to quantify the scope of the alterations through time. Study site selection was based upon a range o f A. tridentata stand replacing fire histories spanning approximately 20 years and subsequent colonization of each fire site by B. tectorum. Fire sites sam pled w ere invaded by B. tectorum fo llow in g a single fire event; the earliest plot was burned in 1985 with subsequent sites having fires in 1987, 1998, and 2002. Sites characterized by^L tridentata, and not burned, were sampled as controls. To assess soil physical and hydrological properties measures o f aggregate stability; hydrophobicity; |
