Vascular ‘halophytes,’ upper intertidal

“Halophytes” are salt tolerant plants (Not salt-loving plants, halophiles, as the ecologist John Thilenius memorably insisted!) The community of vascular halophytes (as opposed to algae) in the upper intertidal is known as the salt marsh. It’s helpful to further subdivide the salt marsh into the high marsh, populated mostly by slightly tolerant grasses, and low marsh, dominated by more tolerant Lyngbye sedge.
