PIE LTER study of marsh vegetation percent cover at Greenwood Creek, Ipswich, MA effluent enrichment and Clubhead Creek, Rowley, MA reference sites

Vegetation percent cover data along transects through a nutrient enriched marsh receiving wastewater effluent and a reference (unenriched) marsh. Nutrient enrichment comes from the Ipswich Wastewater Treatment Facility on Greenwood Creek in Ipswich.  The marsh around Clubhead Creek, Rowley, MA was used as a reference.

本数据集包含沿样带（transects）采集的植被盖度（vegetation percent cover）数据，所涉样带分别穿过两类沼泽：一类为接纳污水尾水（wastewater effluent）的富营养化沼泽（nutrient-enriched marsh），另一类为未受营养富集的对照沼泽（reference marsh）。本次研究中的营养富集源自位于美国伊普斯维奇市格林伍德溪的伊普斯维奇污水处理厂（Ipswich Wastewater Treatment Facility）；美国马萨诸塞州罗利镇克拉布海德溪周边的沼泽则被用作对照沼泽。
