A rich variety of life on Earth is crucial to sustain the planet’s healthy ecosystems. Learn about the importance of biodiversity, explore the interwoven relationships between plants and animals, and investigate the roles of pollinators.

Birds are great indicators of ecosystem health. Learn about some of Oakland’s birds, how to use binoculars to find them in your local environment, and what you can do to support their native habitat.

Oakland's coast redwoods are remarkable ecological giants that are the keystone of the Fern Ravine ecosystem. Learn about the dramatic history and resilient rebound of this forest, the unique intersection of environs (wetland, riparian, redwood forest) at the headwaters of the Sausal Creek, and their ecological and climate-regulating services for plant, animal, and human communities in Oakland.

Sausal Creek’s wild rainbow trout population is a vital natural and cultural resource of Oakland. Protecting and preserving their habitat conserves biodiversity in our urban environment and ensures the long-term health of the creek ecosystem. Learn about the life cycle of a rainbow trout, discover their importance in the food chain, and see a real rainbow trout specimen.

Our landscapes and communities are all connected by water. See a watershed in action, learn about the unique plant and animal residents of Sausal Creek, and get hands-on experience with habitat restoration.

* This field trip is typically hosted at Dimond Park but can also be hosted at Josie De La Cruz Park for schools that are within walking distance and would otherwise not be able to attend a field trip due to transportation challenges.

Our urban waterways face many challenges caused by human impact. Explore how our actions affect water quality, investigate how Sausal Creek’s biodiversity depends on clean water, and gain hands-on experience using water quality monitoring tools and collecting data.
