Which term refers to the ecosystems located in the southern Barrier islands inward from the Atlantic Ocean?

The term "Barrier Islands" accurately describes the ecosystems located along the coast, specifically in the southern region inward from the Atlantic Ocean. Barrier islands are elongated landforms that run parallel to the coastline and are typically formed from sediment deposited by waves and currents. They play a crucial role in protecting the mainland from storm surges and coastal erosion, which is an essential function in Florida due to its extensive coastline.

These islands can host a variety of ecosystems, including beaches, dunes, and wetlands, making them biodiverse and ecologically significant areas. While sand dunes are a component of barrier islands, they do not encompass the other ecosystems present there. Coastal wetlands may exist in relation to barrier islands, but they specifically refer to the wetland areas, rather than the islands themselves. Lastly, the Queen Sago is a type of plant and does not pertain to the geographical or ecological characteristics of the southern barrier islands. Therefore, identifying "Barrier Islands" as the relevant term encompasses the entire ecological context of these coastal regions.
