Working Together to Save a Crucial Wildlife Habitat in Los Angeles-San Fernando Valley

MISSION STATEMENT

We are pledged to preserve the largest remaining natural area in the northwestern San Fernando Valley region of the City of Los Angeles, with an Ecology Pond, seasonal wetlands and vernal pools, grasslands, oak woodlands and savanna, and riparian areas. We are working together to preserve all wildlife, and cultural and archaeological assets.

PURPOSE

The CNP Coalition has formed to protect this precious open space as a nature preserve for wildlife and to prevent any development or modifications that will negatively impact the habitat. The long-term vision is to incorporate the CNP within a larger network of wildlife corridors and protected open space.

BACKGROUND

The Chatsworth Nature Preserve (CNP) is a major City of Los Angeles open space preserve teeming with wildlife. More than 200 species of Birds are on site including, Residents: Greater Roadrunner, California Quail, woodpeckers, herons and egrets; Migrants: Canada Goose, Western Meadowlark, Tricolored Blackbird, and sapsuckers as well as a variety of ducks and shorebirds; Raptors: Ferruginous Hawk, Red-tailed Hawk, Prairie Falcon, Long-eared Owl, and many others. There are notable Amphibians and Reptiles: western spadefoot toad, slender salamander, western skink, ring-necked snake, red racer and much more. The fauna includes large and small Mammals: desert cottontail rabbit, gray fox, coyote, raccoon, and occasional visits of bobcat, cougar and mule deer. Habitats include oak woodlands and savanna, riparian areas, chaparral, grassland, and an Ecology Pond. The seasonal wetlands, and vernal pools, as well as portions of the grasslands and riparian areas are now under threat by a poorly conceived modification project.

Film and TV
Like other picturesque parts of Chatsworth, the Chatsworth Nature Preserve --formerly Chatsworth Lake-- was a popular filming location for movies and TV. The rugged beauty of the regions' rock outcroppings, boulders, canyons, majestic oak trees, grasslands and lake became the cinema backdrop for "B" Westerns or "oaters". Movies filmed on CNP land included The Ten Commandments, Donovan's Brain, The Palomino, Susanna Pass, Sioux City Sue, Man from Rainbow Valley, Out California Way, Home on the Range, Hell's Angels, Tess of the Storm Country, and Three Word Brand. Television filming included The Adventures of Rin Tin Tin and Rin Tin Tin II, as well as the Dukes of Hazard.
