End of Year Biomass for the 1st UPC Inundation Experiment in Upper Phillips Creek marsh 1999-2014

The objective of this study was to determine the individual and compound effects of inundation and wrack deposition on high marsh community structure. Inundation pattern and wrack presence were manipulated individually and in combination, in two neighboring communities (a Juncus roemerianus-dominated and an adjacent Spartina patens and Distichlis spicata-dominated) in 1994 and 1995. Aboveground biomass was used to assess marsh response to the stressors of increased inundation and wrack presence (Tolley and Christian 1999) and continues to be collected from these experimental plots on an annual basis. Details of initial manipulation may be found in: Tolley, P.M. and R.R. Christian. 1999. Effects of increased inundation and wrack deposition on a high salt marsh plant community. Estuaries 22:944-954.
