The response of Olney bulrush and marshhay cordgrass to irrigation with water of differing salinities during drought and to burning was studied at Rockefeller Refuge and in a greenhouse. Twenty ppm salinity decreased culm density. Water levels above the soil surface increased bulrush culm height and density; water levels below the surface had the opposite effect; marshhay cordgrass was not affected by different water levels. Burning in fall, winter, and spring, and during increasing and decreasing moon phases had no effect on culm density of either species. [From author's abstract]
