Halophytes are plants that thrive in saline environments, such as salt marshes, coastal areas, and salt flats. They have specialized adaptations, like salt-excreting glands or succulent tissues, that allow them to manage high salinity levels. These plants play a crucial role in their ecosystems by stabilizing soil, providing habitat for wildlife, and contributing to carbon sequestration. Examples of halophytes include saltbush, mangroves, and certain types of seagrasses.
