Natural History of Fort Tejon

The plant and animal life to be found here is unique due to the park’s geographical location at the confluence of several ecological regions, including the Mojave Desert, the Central Valley, the Sierra Nevada, and southern California. The park’s natural vegetation is dominated by oak woodlands, which provide forage and shelter for a variety of wildlife, including the California condor. Look for scrub jays, as well as red-shafted flickers and other woodpeckers, who feed on the acorns. The presence of a year-round creek in an otherwise arid climate also serves to attract many animals to the park, and the riparian woodland and freshwater marsh along Grapevine Creek are home to myriad birds and reptiles. Almost all of the mammals found in the area, which include blacktailed deer, blacktailed hare, Beechey ground squirrels, bobcats, badgers, and opossum, frequent these wetlands during the summer for water. The park’s meadows and grasslands are home to insects, seed-eating birds, and small mammals. As a result, they are also fertile hunting grounds for raptors, coyotes, and gray foxes.

The land the park sits on is highly active geologically. This area experienced one of the greatest earthquakes ever recorded in the U.S. In 1857 an earthquake of approximately 7.9 to 8.2 magnitude struck here along the San Andreas Fault, leaving an amazing surface rupture scar over 220 miles long.
