We are interested in the differences between these two ecosystem states and how the postulated transition is controlled. The experimental design involves 3 blocks, each containing 3 plots of marsh. Each plot is 3 X 4 m positioned such that approximately 3 X 2 m is in a J. roemerianus stand and 3 X 2 m is in a mixed stand of D. spicata and S. patens . Pumping began in spring and was stopped in fall with occasional interuption from system's failure. The following presentations by James Taylor and Patty Tolley provide an initial summary of results from our work during 1994.
Further analysis is underway.
Both students will use their data for their master's theses at East Carolina University.
