Aboveground biomass data from control sites in a Spartina alterniflora-dominated salt marsh at Law's Point, Rowley River, Plum Island Ecosystem LTER, MA.

Aboveground biomass is determined non-destructively at permanent, high marsh control (non-fertilized) plots in a Spartina alterniflora-dominated salt marsh on the Rowley River within the Plum Island Ecosystem (PIE) LTER site, MA.

本数据集在美国马萨诸塞州普卢默岛生态系统（PIE）长期生态研究（LTER）站点内罗利河沿岸以互花米草（Spartina alterniflora）为优势种的盐沼中，于永久高潮滩未施肥对照样地开展了地上生物量的无损测定。
