5th Graders from Merced Public Schools

In spring, Reserve staff and "Splash" educators from Sacramento teach K-12 students about vernal pool ecology

Sightings on Reserve

Our motion sensor camera photographed this Great Blue Heron and three White-faced Ibis foraging on the Le Grand Canal leakage wetland on an August afternoon.

Stock Ponds

Stock ponds provide drinking water for the 1,600 cattle that graze on the Reserve. Some ponds are breeding sites for the federally threatened California Tiger Salamander.

Burrowing Owls Dwell in Reserve

Burrowing Owls roost and nest in the burrows of California Ground Squirrels. They feed on beetles, grasshoppers and small rodents.

Reserve Hike

UC Merced staff, faculty, and students set out with Reserve staff to explore Black Rascal Creek. Check out the Events section for our next hike.

The Wild Side

The Reserve supports many native plants and animals that depend on this diverse, healthy ecosystem. This Least Sandpiper is foraging in a playa vernal pool.

Vernal Pool Research

Vernal pools are fascinating, but rare ecosystems. Scientists have much to learn about the geological and hydrological processes that create and maintain them.

Predation In Action

One of our automatic, motion cameras snapped a photo of a Bobcat carrying off a California Ground Squirrel, reflecting predator-prey relationships.

Horned Lark Nest

Horned Larks are abundant nesting birds on the Reserve. Their nest is placed on the ground, often near a grass clump or cobble. Photo by Jenna Heckel.

Lizard Sighting

On August 6, 2015 we spotted the first common side-blotched lizard recorded on the Grasslands Reserve
