A. Burd (UGA) and Y. Jung (UGA graduate student) have been developing a computer model to predict growth and competition between three plant species (S. alterniflora, J. roemarianus and B. frutescens). This model will help improve our understanding of the processes leading to plant zonation in the marsh. They are starting by updating and extending an earlier model created by Wiegert and Wetzel for a Spartina salt marsh. This model will form a context for the final plant model.

Area 3: Responses to Salinity and Inundation (more information) Question 4: What are the underlying mechanisms by which proximity of marshes to upland habitat drives ecosystem change along lateral gradients in the intertidal zone? (more information)
