K. Wasson, A. Woolfolk, N. D'Amore and S. Fork are carrying out an experiment manipulating nutrient levels in two ESNERR marshes. By comparing pickleweed growth in fertilized and unfertilized plots, they will be able to determine whether the marsh is nutrient limited, and if not, how it responds to enhanced nutrient levels. These plots will also be used by D. Siciliano (UCSC) to compare hyperspectral signatures of high vs. low nutrient pickleweed and by ESNERR researchers studying the host-parasite relationship between marsh dodder and pickleweed.
