Aboveground biomass from control sites in a Spartina alterniflora-dominated salt marsh at Stackyard Rd, Nelson Island, Parker River NWR, Plum Island Ecosystem LTER, Rowley, MA (2019-2023).

Aboveground biomass is determined non-destructively at permanent, control (non-fertilized) plots in a Spartina alterniflora-dominated salt marsh on Nelson Island near Stackyard Rd in the Parker River NWR within the Plum Island Ecosystems (PIE) LTER site, MA.本数据集的地上生物量采用非破坏性方法测定，测定样地位于美国马萨诸塞州的普拉姆岛生态系统长期生态研究（PIE LTER）站点内，具体地处帕克河国家野生动物保护区（Parker River NWR）斯塔克亚德路附近的纳尔逊岛，设置在以互花米草（Spartina alterniflora）为主的盐沼中，均为永久对照（不施肥）样地。
