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

The MVSD Wetlands Education Program started in 1996 by providing field trip experiences to Martinez elementary schools. The program has grown over the years and now includes a field trip experience and a classroom program. MVSD partners with the Lindsay Wildlife Experience (LWE) on presenting a curriculum aligned with California Science Standards for both programs. Now, 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 these complimentary experiences.

Students watching birds during the wetlands hike in Moorhen Marsh.

The Wetlands Field Trip Program is a 4-hour experience where 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. The Wetlands Field Trip Program is expected to return January -May 2023.

The Wetlands Classroom Program is a 1-hour experience offered in winter, where LWE instructors visit Contra County elementary school classrooms. Teachers select from three available programs:  Craft a Wetland Critter, Water Quality for Life, and Wetlands Wonder. The classroom programs have been extended into September 2022-January 2023. Programs are available Tuesdays, Wednesdays and Thursdays.

We believe that these programs benefit 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.
