Coastal wetlands are unique systems which often display zonation of the species which inhabit it. While often thought to be caused by abiotic conditions, I hypothesized that plant interactions may play a key role. I examined the plant interactions in situ between Schoenoplectus americanus (sedge) and Spartina patens (grass) across an elevation gradient using aboveground removal treatments. Six blocks composed of 4 plots each (0.5 by 0.5 m) were subjected to one of four treatments; no removal (control), all removal, sedge removal, or grass removal. Results showed that competition was a driving force behind the community structure of the marsh. I then examined the role of N in this relationship in a greenhouse study. The results suggest competition is impacted by high N levels, at which grass show a greater competition effect from the sedge. My research suggests both species interaction and abiotic factors impact marsh community structure.
