The research we have been working on is part of Andy Bunn's research thesis. He is currently a PhD student at Montana State University. His research revolves around forest simulation modeling and addresses the dynamics of treeline over the last millennium in response to climate variation. Field crews are sent to the Sierra Nevada Mountains to collect data, survey selected plots and extract cores form trees, this information is used to evaluate climatic mechanisms controlling forest composition, structure and dynamics. His results will be published in scientific journals and presented at conferences.Yuma Proving Grounds are using Quik Stakes...but how is classified.
