Viewing of managed wetlands.
In the fall and winter this area is seasonally filled with water to support migratory and resident birds and waterfowl, as well as roosting habitat for Sandhill cranes.
In the springtime, this area transforms into a vibrant display of wildflowers, most notably the purple Downingia—commonly known as “calicoflower.” These delicate blossoms thrive in seasonal wetlands and add a striking splash of color to the landscape.
In managed wetlands, resilience can be seen in how the landscape responds to changing water availability and temperature throughout the year. Key indicators to track include:
Water Level Variability – Timing, depth, and duration of seasonal flooding and how wetlands respond during drought years or heavier-than-average rainfall.
Vegetation Response – Germination and bloom timing of native wetland species (such as Downingia), plant diversity, and the presence of invasive species.
Wildlife Use – Seasonal abundance and diversity of migratory birds, waterfowl, and roosting Sandhill crane.
Soil & Habitat Condition – Signs of soil stability, erosion, or changes in wetland extent.
Phenology Shifts – Changes over time in flowering periods, migration timing, and wetland drying patterns.
Tracking these indicators helps assess how well the wetland adapts to drought, extreme rainfall, and long-term climate variability while continuing to support habitat and biodiversity.
The Cosumnes River Preserve consists of over 50,000 acres of wildlife habitat and agricultural lands owned by seven land-owning Partners. The Partners include The Nature Conservancy, Bureau of Land Management, California Department of Fish & Wildlife, Sacramento County Regional Parks, Department of Water Resources, Ducks Unlimited, and the California State Lands Commission. The Preserve is centered along the Cosumnes River, its floodplains and riparian habitat. This habitat is buffered by a variety of agricultural operations. The Preserve provides numerous social, economic, and recreational benefits to local communities and to people residing in the larger Sacramento and San Joaquin areas. The habitat supports wildlife, including birds that migrate throughout the Pacific Flyway.
