Plant heights at control and fertilized plots in a Spartina alterniflora-dominated marsh, Law's Point, Rowley River, Plum Island Ecosystem LTER, MA (1999-2024).

Plant heights are measured during the growing season in permanent plots at a Spartina alterniflora-dominated salt marsh on the Rowley River within the Plum Island Ecosystems (PIE) LTER site. Plant heights are converted to plant weight using an algorithm to generate a non-destructive estimate of aboveground plant biomass.

本数据集的相关测定工作在普拉姆岛生态系统（PIE）长期生态研究（LTER）站点内的罗利河沿岸、以互花米草（Spartina alterniflora）为优势种的盐沼永久样地中开展，于植物生长季测定植株株高。通过算法将测得的株高转换为植株重量，以此实现地上植物生物量的无损估算。
