Woodbridge Ecological Reserve (AKA Isenberg Crane Reserve)

flocks of birds at Woodbridge ER


Description

One of CDFW's objectives is to maintain ecological reserves and marine protected areas intended to conserve unique, fragile habitats, which can function to protect and restore rare and threatened native species. The greater sandhill crane population has diminished in California to a point where they were listed as a threatened species in 1983. The Stockton delta wetlands (inclusive of the 353-acre Woodbridge Ecological Reserve) provide the largest area of freshwater marsh wintering habitat in the state, not only for sandhill cranes but for other waterfowl as well.

Sandhill cranes, Canada geese, snow geese, tundra swans, and many other birds use the reserve as their fall and winter home. Local residential birds include the red-wing blackbirds, black-shouldered kite and American kestrel, ring-necked pheasant, meadowlarks and other small songbirds.

For more information, call the reserve at (209) 234-3435 or the Bay Delta Region Napa office at (707) 944-5500.

Area History

The south site of the reserve was purchased by CDFW in October of 1985 from the El Dorado Duck Club. The 145-acre Duck club was one of the only destination points along Woodbridge Road following the early Delta reclamation efforts. In 1986, the property was designated as an ecological reserve by the Fish and Game Commission.

During the spring and summer months the area is drained and allowed to dry out. During the days of the El Dorado Duck Club, cattle were brought in to use the land for grazing. Today, the Department of Fish & Wildlife allows the land to lay fallow and rest during this period. Large mowers pulled behind tractors are brought in during early summer to keep the height of the vegetation at a manageable level, creating an ideal upland grassland habitat.
