PIE LTER plant biomass associated with marsh sites used in space for time sea level rise study, Rowley, MA.

This dataset contains the mass of dried grasses collected from clip plots in the PIE LTER Space for Time Sea Level Rise  study. The space for time  study uses an intensive and comprehensive approach to compare low elevation, Spartina alterniflora marsh areas to higher elevation Spartina patens marsh areas. Grasses are sampled in plots from 4 transects per site with five plots per site, arranged from the tidal creek's edge to no more than 150 meters back from the creek.

本数据集包含采自PIE LTER "空间替代时间海平面上升"研究中刈割样方的干燥草本植物样品。该空间替代时间研究采用精细化且全面的研究方法，对比低海拔互花米草（Spartina alterniflora）盐沼区域与高海拔海滨米草（Spartina patens）盐沼区域的特征。草本样品采自各研究样地的样方：每个样地设置4条样带，每条样带布设5个样方，采样范围从潮汐沟边缘延伸至距沟岸不超过150米的区域。
