Traditional techniques for gathering environmental data, such as periodic field studies or satellite imaging, do not produce adequately detailed or persistent information. Self-organizing wireless networking provides an ideal way to quickly deploy and gather data from sensor networks in the field. The design of a practical, low-cost, and self organizing wireless sensor network, TephraNet, is examined. This thesis also explores an implementation and deployment of TephraNet in Hawaii Volcanoes National Park to learn about the endangered ground plant Silene hawaiiensis.</dim:field>
