Managed by the U.S. Fish and Wildlife Service, the San Diego Bay National Wildlife Refuge is where we host our coastal education field trips. We also host birding events at this site as it provides a great trail to walk and a platform to enjoy the views and spot birds! After visiting Crestridge Ecological Reserve, students get a second field trip at the San Diego Bay National Wildlife Refuge Sweetwater Marsh. During this field trip, students build on the foundations they learned at Crestridge by exploring a new habitat—the salt marsh! For many students, this is their first time seeing the coast and the wildlife that live in the salt marsh habitat. Our activities here include water quality testing, science illustration, bird adaptation puzzle games, and birding with binoculars. At this location, students work together to restore coastal sage scrub habitat by planting a variety of species. Between Crestridge Ecological Reserve and the San Diego Bay National Wildlife, students become acquainted with inland and coastal habitats, and the interconnection between these ecosystems.
