Mapping Monarch Butterfly Clusters
Authors: David Yun
Pismo Beach Monarch Butterfly Grove located south of the Pismo Beach, California is a well-known monarch butterfly overwintering site. Monarch Alert, a citizen based research project, monitors monarch butterfly population. The data contained population count information but did not have specific cluster location information. A new method of data collecting designed and managed by GIS enabled the data to be viewed in 3D space for better understanding of cluster movement in all direction.
