The park preserves one of few intact examples of native grasslands on the floor of the Central Valley. The park is part of the larger Grasslands Ecological Area (GEA) of federal, state and private lands all managed for wildlife values. The GEA represents the largest remaining contiguous block of wetlands in California. Several rare and endangered plant and animal species inhabit the park, including alkali sacaton, a native bunch grass, and the Delta button celery (Eryngium racemosum) a state listed endangered species found in the flood plain of the San Joaquin River. Biologists have also reported the California Tiger Salamander and endangered vernal pool fairy shrimp and tadpole shrimp. Springtime wildflower displays, fishing and wildlife watching attract visitors to this undeveloped park, which also encompasses the former Fremont Ford State Recreation Area.
