The purpose of the study is to understand the differences in the snowpack between these two areas. . Dylan Brown. Winter Ecology Spring 2014. Mountain Research Station, University of Colorado Boulder. Introduction. Mountain pine beetles are increasing the number of dead trees in our forests. Dead trees with no remaining needles intercept less snow and solar radiation than live trees (Pugh and Small, 2011). Presentation: Liz Westby. Assistant: Esther Duggan. October 30, 2012. Description.
