Preliminary Dissertation Subject: Exploring the influence of aspen chemistry and the nutritional context on ungulate aspen herbivory

My current project deals with identifying the nutritional and secondary chemical thresholds that drive preference for or against aspen (Populus tremuloides) using sheep in pen trials.  Using information on preference gained from the pen trials coupled with primary and secondary chemistry of aspen leaves, nutrition of surrounding understory, and animal use via pellet counts I will be creating spatio-temporal herbivory risk-maps for aspen on a small-scale area near Kamas, UT in Wolf Creek Ranch.
