History
The South Fork Kern River is home to California's largest lowland riparian forest. It is one of four "Flagship Projects" of the California Riparian Habitat Joint Venture. A shared effort between Audubon-California and The Nature Conservancy (TNC) saved 1,136 acres of this forest. In May, 1999, 156 acres of land forming the new Kelso Creek Sanctuary of the Kern River Preserve was purchased by Audubon. On March 31, 2005, Audubon acquired 1,640 acres ofSprague Ranch. Because of this purchase Audubon’s Kern River Preserve now includes another 5 miles of frontage on the South Fork Kern River. Then in early 2006, another 105 acres was acquired from the Alexander family. In 2009, two parcels were purchased from heirs of the Alexander family for a total of 106 acres. At last count the total acreage of the contiguous preserve to 2,987 acres.
The Kern River Preserve, and environs, was one of the first ten sites in the U.S. to receive "Globally Important Bird Area" recognition. 339 bird species have been recorded here. Most significantly, two hundred species nest here including major breeding populations of Yellow-billed Cuckoo, Summer Tanager, and Willow Flycatcher. Audubon-California is engaged in a habitat enhancement program to benefit the Preserve's nesting wetland species including Wood Duck, Mallard, and Cinnamon Teal.
History of the Kern River Preserve
Prior to becoming a preserve, the land was locally known as the A. Brown Ranch. The land had been operated as a cattle ranch since the mid-1800s.
Natural Resources in the Kern River Valley
Audubon Kern River Preserve protects part of the South Fork Kern River, a tributary of the Kern River. During high water years part of the preserve now rests under Isabella Reservoir, an artificial lake dedicated in 1953 for the purpose of irrigation and flood control for the southern San Joaquin Valley.
