What is meant by "tidelands" in the context of critical areas?

The term "tidelands" refers to areas that are periodically flooded by tidal waters. This includes coastal regions that are affected by the ebb and flow of ocean tides, resulting in regular inundation and exposure of the land. The importance of understanding tidelands lies in their environmental role, as they support unique ecosystems and serve vital functions such as water filtration, flood protection, and providing habitat for wildlife.

Recognizing this specific definition helps in grasping the significance of critical areas, especially concerning land use and environmental protection policies. Other options, like land that is always submerged or close to the coast, fail to accurately capture the dynamic nature of tidelands, which specifically experience regular alternation between being underwater and being exposed.
