Students participate in the dip-netting activity during the wetlands field trip program.

Developed and performed as a partnership between MVSD and the Lindsay Wildlife Experience (LWE), the Wetlands Field Trip Program started providing field trips for students in Martinez Elementary schools in 1996. Today, thanks to various grant programs, private donations, and revenues from MVSD’s cell tower and billboard leases, students from schools throughout Contra Costa County can participate in the complimentary field trip experience.

Students watching birds during the wetlands hike in Moorhen Marsh.

During the 4-hour program, students explore Moorhen Marsh, dip net for aquatic animals, tour MVSD’s treatment plant, and learn about water pollution prevention and aquatic animal adaptations. While participating in the wetlands hike, students look for mammal signs like tracks and scat from species including river otter, black-tailed deer, grey fox, and even mink! Students also get the opportunity to learn how to find and observe birds like great blue heron, Canada goose, pied-billed grebe, and red-shouldered hawk. Dip-netting activities allow for close up inspection of a variety of fish and invertebrate species including three-spined stickleback, mosquito fish, dragonfly nymph, amphipods, and crayfish. The treatment plant tour gives students a first-hand look at how wastewater is treated so it can safely be returned to the environment and how everyone can participate in keeping our creeks and waterways clean by learning what is safe to pour down the drain.

We believe that this vital partnership between MVSD and LWE benefits both our community’s school students as well as the county’s fish and wildlife by increasing awareness, appreciation, and understanding of the functions and values of wetland habitats and the wildlife they support.
