marshland
Wet, squishy land covered with water and tall grasses.
A marshland is a type of wetland where the ground stays waterlogged and soft, covered with grasses, reeds, and low plants rather than trees. If you've ever walked where the ground squishes under your feet and water seeps up around your shoes, you might have been at the edge of a marsh.
Marshlands form in low-lying areas where water collects but doesn't flow away quickly. Unlike swamps, which have trees, marshes are mostly open, with tall grasses and cattails growing up through shallow water. The water level can change with the seasons: deeper in spring, shallower in summer.
These soggy places might look empty or useless, but they're remarkably important. Marshlands filter pollution from water before it reaches rivers and oceans, and they absorb floodwaters like a giant sponge, protecting nearby towns. They're also home to an incredible variety of life: ducks and herons nest there, fish spawn in the shallow waters, and frogs fill the air with their evening chorus.
Many famous marshlands exist around the world, like the Everglades in Florida or the marshes along the Nile River. Before people understood their value, marshlands were often drained to create farmland, but today scientists work to protect these vital ecosystems.
