03. Salt Flat
In the salt marsh, there are often, but not always, open sandy places where nothing grows. These areas are called salt flats. They are the saltiest places in the salt marsh, too salty for most plants. They are salty because they are flooded at highest tide, and then the sun and air cause the water to evaporate but leave behind the salt. Around the edges of the salt flats some specialized, salt-loving plants can grow, such as glasswort and salt grass.
