Aboveground biomass at control and fertilized plots in a Spartina patens-dominated salt marsh, Rowley River, Plum Island Ecosystem LTER, MA (2000-2024).

Aboveground biomass is determined destructively at control and fertilized sites approximately monthly during the growing season at a Spartina patens salt marsh on the Rowley River within the Plum Island Ecosystems (PIE) LTER site.研究人员于普卢默岛生态系统（PIE）长期生态研究（LTER）站点范围内罗利河沿岸的帚状米草（Spartina patens）盐沼中，在生长季内以约每月一次的频率，对对照组与施肥样地开展破坏性采样以测定地上生物量。
