Impounded marsh at Jacob's Point. This photo was taken from the footpath tidal restriction. Invasive Phragmites can be seen in the background encroaching upon the native high marsh.







Unimpounded, healthy side of Jacob's Point near it's outlet into the Warren River. This is a photo of low marsh dominated by Spartina alterniflora, saltmarsh cordgrass.







Native Phragmites stand on left, invasive Phragmites on right. This is the only documented stand of native Phragmites in mainland Rhode Island. Block Island has several more stands.
