The vegetational zonation of the East Pen Island salt marshes, Hudson Bay
The extensive salt marshes at East Pen Island in Hudson Bay are described in quantitative terms and the well-marked sequence of species is characterized. The lower marsh is dominated by Puccinellia phryganodes and Carex subspathacea, with Hippurus vulgaris and Senecio congestus abundant in the salt...
