This emergent aquatic, with its leaves and flowers above water and portions of the stem under water, is found typically in shallow, quiet water. The seeds can be eaten like nuts and the young leaf-stalks cooked as greens. Deer also feed on these plants. The common name suggests that this plant, as well as the fish known as pickerel, occupy the same habitat.

The oldest type of net used by the Chesapeake Bay watermen is called a pound net. Wooden stakes are pushed into the bottom of the Bay, spaced apart in a line that runs across the tide. Nets are strung between the stakes and along the bottom of the river, making a fish trap. In late February the pound netter starts to put in the stakes. By the middle of March he will set his nets and start fishing. Each day the waterman goes out to the pound net and scoops the fish out with a hand net. He will not remove the pound net, except for many repairs, until November.

These traditional boats tended to the oyster fleets working the beds in the Bay, buying harvested oysters from the oystermen in the afternoon, and running those oysters to faraway markets and rail centers in Norfolk, Crisfield, Baltimore, and Washington DC, and to local shucking houses and canneries around the Bay.

This nematode worm is a parasite, originally from Southeast Asia. With the American eel population already declining, the introduction of this nematode may have a large negative impact on the survival of this species.

Pickleweed is an invasive or introduced plant in Hawaii. It has succulent, brilliant green leaves and is common in salt marshes and tidal shorelines. It grows slowly in soils with high salt concentrations and areas with seawater overwash where it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves.
Batis maritima (Pickleweed)
In the section of the river above the dam builds up with sediment, making the dam shallower. High water flow causes scouring and the transport of sediment and associated nutrients over the dam. On this other side of the dam phosphorus mobilizes in reaction with salt water. Further down the river seagrass beds grow on the Susquehanna flats.

Badlands National Park sits upon highly erodible sedimentary rocks that form distinctive pinnacles, gullies and spires. Threats to the park include illegal fossiling and the invasion of weeds and non-native grasses.

Some of the most common threats to the national parks ecosystems include those to quality of air, quality and quantity of available water, and the parks native species. Prescribed fire is used to prevent uncontrolled forest fires and to reduce the growth of nonnative species.
