Sedges & Reeds

Sedges and Reeds are superficially similar, but actually quite different. But unless you are a biologist - who cares? ( Reeds are grasses, sedges are sedges. )

Sedges

Sedges tolerate a wide range of salinity, from freshwater to seawater, although they seem to grow best in brackish water. So, like above, if you are exploring a bay or inlet, that stuff all around you is most likely sedge.

Channels like the one above are not natural, they are cut primarily for mosquito control. Mosquito larvae need still water, and the tidal flow helps flush them out, while also allowing access for fish to feed on them. That's the idea, but it is not 100% effective, so bring your bug spray.

Reeds

One well-known reed is the Cattail. This member of the grass family tolerates brackish water, but is found most often in fresh.

Here is a map you can use to see just water features. The level of detail increases as you zoom in. The boundary lines have been deleted, as they often follow and obscure water features. It is interesting to trace the rivers to their headwaters.

In the north, the state's two largest river systems are the Passaic and the Raritan, which intertwine. In the south, the Mullica forms a sizable river system. Only one river originates in New Jersey and leaves the state - the Walkill in the north. All others are captured by either the Delaware or the Hudson, or the extensive southern bays. The orange line is approximately the dividing line between east (Hudson/Atlantic) and west (Delaware River) drainages. The red line is the "fall line" - the boundary between the Piedmont uplands and Atlantic coastal plain. And that's your lesson in hydrology.
