The Madrona Marsh Preserve is a mix of several micro-habitats including back dune, coastal prairie, alkali margin, vernal pool and vernal marsh area and is situated within the greater El Segundo Sand Dune System. The fine sand particles of this ancient dune system have been carried from the coastal dunes by winds for thousands of years. Each of the Preserve's habitats houses its own specifically adapted native plant species.

The Preserve provides a valuable habitat for birds, insects, spiders, frogs, reptiles and small mammals. It is one of the last vestiges of the extensive marshland that once covered the Southern California Coastal Plain.
