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

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.

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.

Drought leaves stock ponds dry

With only 2 inches of rain so far this year, cattle stock ponds are dry or nearly dry.

Science Education

The Vernal Pools and Grassland Reserve is convenient and accessible to undergraduates. A number of professors now hold field trips there.

At UC Merced we're trying to help kestrels by erecting nesting boxes along fence rows in the Reserve. Kestrels are small relatives of the lightening fast Peregrine. But unlike all other North American falcons, the kestrel is a cavity nester. They take over an old woodpecker nest in a tree. However, suitable nest...
