Present a report to the class or make a bulletin board describing each type and ways that people and animals use them. While this area may not look like home to many animals and few or no plants grow here, there are lots of creatures living down in the substrate. Low-lying grassy areas may fill with rain and stay wet for several weeks. These areas often seem alive with the high-pitched calls of frogs looking for mates. In the heat of the summer, these areas usually dry up for a while.
Plants here are valuable food sources for ducks, geese and swans.
Tall grasses and other kinds of plants grow up out of the water. Even though the water has little or no salt, the tides push the rivers up far enough to change the water level here, so the ground is sometimes flooded and sometimes dry. The plants provide food and places to hide for many kinds of animals, including fish, snails, muskrats and lots of birds. Where trees grow in low-lying areas, the ground may hold water for part of the year. In the spring, many beautiful wild flowers grow here, and frogs and salamanders find wet places to lay their eggs.
