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 (2019-2024).

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 (Aboveground biomass) 均通过无损方式测定，采样样地位于美国马萨诸塞州普拉姆岛生态系统（缩写PIE）长期生态研究（LTER）站点范围内的帕克河国家野生动物保护区（Parker River NWR），具体为斯塔克亚德路附近纳尔逊岛的一片以互花米草 (Spartina alterniflora) 为优势种的盐沼中的永久对照（未施肥）样方。
