Why may salt-tolerant plants use coastal habitats as migration corridors?

Salt-tolerant plants, or halophytes, utilize coastal habitats as migration corridors because the saline soil conditions found in these areas are similar to those present in deserts.

Because these plants are physiologically adapted to survive in salty environments, they can thrive in both desert and coastal ecosystems. This environmental overlap allows coastal regions to serve as effective pathways for plant migration between discrete desert regions. Furthermore, the dispersal process is sometimes facilitated by ocean currents, which can transport buoyant seeds between different coasts, enabling these plants to colonize new areas before eventually spreading into inland desert environments.1
