Annual primary productivity of Spartina alterniflora in control and fertilized plots at Law's Point, Rowley River, Plum Island Ecosystem LTER, MA.

Annual productivity is determined from aboveground biomass data in a Spartina alterniflora-dominated salt marsh plots on the Rowley River within the Plum Island Ecosystems (PIE) LTER site. Aboveground biomass is determined non-destructively.

本数据集的年生产力数据源自普拉姆岛生态系统（Plum Island Ecosystems, PIE）长期生态研究（LTER）站点罗利河河段内以互花米草（Spartina alterniflora）为优势种的盐沼样地的地上生物量观测数据，且地上生物量采用非破坏性方法完成测定。
