GCE-LTER Data Set Summary

Accession: PLT-GCEM-1309 Research Theme: Plant Ecology (Monitoring)
Contributors: Steven C. Pennings, Sasha Greenspan, Caroline Reddy
Title: Annual monitoring of high marsh plots dominated by Juncus and Borrichia at the GCE LTER from 2013 - 2025
Abstract: Annual monitoring of high marsh plots dominated by Juncus and Borrichia. Plots were established at GCE sites 6 and 10 in 2013, and are monitored annually. The goal is to determine how annual variation in climate and other abiotic factors affects the vegetation composition.
