Aboveground biomass 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.

该数据集的测定对象为地上生物量（aboveground biomass），测定地点设置于美国马萨诸塞州普拉姆岛生态系统（Plum Island Ecosystem, PIE）长期生态研究（Long Term Ecological Research, LTER）站点内的罗利河沿岸互花米草（Spartina alterniflora）优势盐沼，测定方式为对该区域内永久性高潮位对照（未施肥）样地开展无损测定。
