Mechanisms for species success following juniper mastication

Researchers:	Kurt Young, Ph.D. Candidate, Brigham Young University, youngke1@msn.com Bruce Roundy
Study Design and Objectives:	This study will look at a variety of responses to juniper mastication: Evaluate the effects of juniper mastication on Bromus tectorum and Pseudoroegneria spicata seedling success as affected by mastication-altered soil characteristics. Evaluate the effect of location characteristics on juniper decomposition. Develop and use wet-thermal time root growth models to explain initial seedling survival as the upper level of plant available soil water recedes to greater depths in the spring.
