Mean (±SE) above-ground biomass (g dry plant material m-2).
Above-ground biomass A) at Kitty Hawk Woods and Currituck Banks Reserves, B) between Phragmites Density treatments within Kitty Hawk Woods Reserve, and C) between Phragmites Density treatments within Currituck Banks Reserve. Note that the Medium Phragmites Density treatment was present only in Kitty Hawk Woods Reserve. Letters indicate significant differences between levels of a factor.
