Padilla Bay is a relatively shallow, sheltered embayment located in northern Puget Sound, along the mainland coast of Washington.

A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric ds play a number of functions, including water purification, water storage, processing Introduced plant species are far more numerous than the native species.
