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.
